The school board and principal may recommend that students take certain courses in addition to the compulsory credits. However, they may not identify additional courses as compulsory for the OSSD.

See also section 6.2 on substitutions for compulsory credit requirements and section 7.3.1 on locally developed courses.

6.1.2 Optional credits

In addition to compulsory credits, students must earn optional credits by successfully completing courses from the Ontario Curriculum.

Students who entered Grade 9 in 2023 or earlier are required to earn 18 compulsory credits and 12 optional credits.

Students entering Grade 9 in 2024-25 onwards are required to earn 17 compulsory credits and 13 optional credits.

6.1.3 Secondary school literacy graduation requirement

All secondary school students must meet the literacy graduation requirement to earn an Ontario Secondary School Diploma (OSSD). The requirement is based on the expectations for reading and writing throughout the Ontario Curriculum up to and including Grade 9. Its purpose is to ensure students have the reading and writing skills they will need to succeed in school, at work and in daily life.

To meet this requirement, students are expected to take and successfully complete the Ontario Secondary School Literacy Test (OSSLT)in Grade 10 in accordance with policies outlined in section 6.1.3.1. Once students have successfully completed the OSSLT, they may not retake it.

Students who do not successfully complete the OSSLT will have additional opportunities to meet the literacy graduation requirement in accordance with the policies related to the OSSLT (see section 6.1.3.1), the Ontario Secondary School Literacy Course (OSSLC) (see section 6.1.3.2) and the adjudication process (see section 6.1.3.3).

Mature studentsfootnote 2 may enrol directly in the OSSLC without first attempting the OSSLT. They may choose to meet the literacy graduation requirement by successfully completing the OSSLT.

Students whose Individual Education Plan indicates that they are not working toward an OSSD may, with parental consent and principal approval, be exempted from writing the OSSLT or taking the OSSLC.

Students who are working toward an OSSD under the revised edition of “Ontario Schools, Intermediate and Senior Divisions (Grades 7-12 OACs): Program and Diploma Requirement (1989)” or are working toward an earlier diploma, such as the Secondary School Graduation Diploma are not required to meet the literacy graduation requirement.

6.1.3.1 Ontario Secondary School Literacy Test

The Ontario Secondary School Literacy Test (OSSLT) is the usual means by which students meet the provincial secondary school literacy requirement for graduation. The test identifies students who have demonstrated the required skills in literacy as well as those who will need to do further work. Feedback provided on the Individual Student Report highlights areas of focus, as needed.

The administration period is determined by the Education Quality and Accountability Office (EQAO). Schools administer the test as per guidelines stated in the EQAO User Guide for the Administration of the OSSLT. The OSSLT is offered in the fall and spring. Students can attempt the OSSLT during the fall or spring session (or both, if desired, if they are not yet successful on their previous attempt).

Students usually take the OSSLT in the school year following Grade 9, unless granted a deferral by the principal. Deferrals may be granted by the principal in accordance with the policies described in section 6.3.1.4.

Students who do not successfully complete the OSSLT will have opportunities to retake the test, during the next administration period scheduled by the EQAO. Once students have successfully completed the OSSLT, they may not retake it.

English language learners may be entitled to special provisions listed in section 6.1.3.4. For students with special education needs, accommodations specified in their Individual Education Plan must be available on the day(s) of the test (see section 6.1.3.4). For students for whom required accommodations were not available on the day(s) of the OSSLT, see section 6.1.3.3.

Students take the OSSLT in the language of instruction of the school where they are enrolled at the time of the test. School boards should ensure students and parent(s)/guardian(s) are aware of this policy, particularly in those cases of students who may be transferring between the English-language system and the French-language system and who have not fulfilled the literacy graduation requirement. These students will be considered to have met the literacy requirement if they successfully completed the OSSLT in either English or French at their previous board. They will not have to retake the test in the other language after transferring to the receiving board.

School boards must provide remedial assistance for students who do not complete the OSSLT successfully. This remedial assistance could be designed to help students improve their skills so that they are better prepared to retake the literacy test. For example, a board could offer a credit course on learning strategies (see the guidance and career education curriculum) or a course on literacy skills (see the English curriculum) for these students.

For students who entered Grade 9 in the 1999–2000 school year, successful completion of the test was not required. However, for those students who took the field test of the OSSLT in 2000–2001, failed the test and chose to retake the OSSLT in October 2001, successful completion of the provincial literacy graduation requirement became a diploma requirement.

6.1.3.2 Ontario Secondary School Literacy Course

Policy requirements for taking the Ontario Secondary School Literacy Course (OSSLC) are contained in the curriculum policy document The Ontario Curriculum: English-The Ontario Secondary School Literacy Course (OSSLC) Grade 12. Students who pass the OSSLC are considered to have met the literacy graduation requirement.

Once a student has had two opportunities to take the OSSLT and has a result of “not yet successful”, at least once, the student is eligible to enrol in the OSSLC. Principals have the discretion to allow students to enrol in the OSSLC before they have had a second opportunity to take the OSSLT, if the principal determines that it is in the best educational interest of the student. Mature students may enrol directly in the OSSLC, as specified in section 6.1.3. They may also choose to meet the literacy graduation requirement by successfully completing the OSSLT.

The credit earned for successfully completing the OSSLC may also be used to meet the Grade 11 or the Grade 12 compulsory credit requirement in English or to meet the Group 1 compulsory credit requirement for the Ontario Secondary School Diploma. A student cannot be granted credit for the OSSLC through the challenge process from the prior learning assessment and recognition policy (see section 7.2.4).

For students with special education needs, accommodations specified in their Individual Education Plan (IEP) must be available throughout the course. However, because achievement of the expectations in this course represents fulfilment of the literacy requirement for graduation, no modifications of the expectations are permitted.

Students who are receiving special education programs and/or services and have an IEP documenting accommodation required during the taking of the OSSLT may be eligible to enroll directly in the OSSLC if the required accommodations are not available when the OSSLT is administered. The accommodations must be in accordance with those outlined in section 6.1.3.4. In such cases, the student must have been present to take the test but the required accommodations or a reasonable alternative to them, were unavailable during part or all of the test. Students in these circumstances in their graduating year may be eligible for the adjudication process established by their school board (see section 6.1.3.3).

Read more:

6.1.3.3 Adjudication

School boards may establish adjudication panels at the end of the school year to provide students with an additional opportunity to meet the literacy graduation requirement. The process is designed for students who, through no fault of their own, have not been able to take advantage of the normal opportunities to take the Ontario Secondary School Literacy Test (OSSLT) and/or students who have not been able to enrol in or complete the Ontario Secondary School Literacy Course (OSSLC) because of unforeseen circumstances. The ministry will provide boards with the procedures and timelines for the adjudication process.

Students who are otherwise eligible to graduate in a given school year are eligible for adjudication to obtain their graduation literacy requirement if they meet one or more of the following criteria:

  • The student was never able to write the test because of illness, injury or other circumstances.
  • The student was eligible to enrol in the OSSLC but the school did not offer the OSSLC or make arrangements for the student to take it in another school.
  • The student was enrolled in the OSSLC but, because of illness, injury or other extenuating circumstances, was not able to complete the OSSLC.
  • The student was receiving special education programs and/or services and had an Individual Education Plan documenting required accommodations when taking the OSSLT. (The accommodations must be in accordance with those outlined in section 6.1.3.4, under the Permitted Accommodations heading). In that school year or in the previous school year, the student was present to take the test, but, because of unforeseen circumstances, the required accommodations, or a reasonable alternative to them, were not available to the student on the day of the OSSLT was administered during the whole test or part of the test.

Please note that private schools and First Nation/federally operated schools are not able to offer adjudication.

6.1.3.4 The Secondary School Literacy Graduation Requirement: Accommodations, Special Provisions, Deferrals and Exemptions

This section includes information about accommodations for students with special education needs; special provisions for English language learners; rules that apply to deferrals of the OSSLT; and rules that apply to exemptions from the literacy graduation requirement.

1. Accommodations for Students with Special Education Needs Pertaining to the OSSLT and the OSSLC

School boards must provide accommodationsfootnote 3 that allow students with an Individual Education Plan (IEP) to receive a fair and equal opportunity to complete the OSSLT or OSSLC. Accommodations can change only the way the OSSLT is administered or the OSSLC is taught, or the way a student responds to the components of the test or course. They do not alter the content of the test or the expectations of the course, nor do they affect the validity or reliability of the test or the evaluation of student learning in the course.

To qualify for accommodations during the test or course, a student must have an IEP that outlines the accommodations to be provided. A student may have an IEP whether or not they have been formally identified as exceptional by an Identification, Placement and Review Committee (IPRC).

Accommodations may be necessary for some students with disabilities and/or special education needs to ensure their equitable participation in the course or test. Accommodation needs must be considered in advance, and principals must plan carefully to ensure they are provided.

(1a) Procedures for making accommodations

Certain basic procedures must be followed in planning and making accommodations to ensure maximum benefit to the student. Decisions about accommodations must:

  • be made on an individual student basis
  • be made by the principal in consultation with the student, their parent(s)/guardian(s) (if the student is under the age of 18) and appropriate staff (including special education and professional support services staff)
  • be made before the student takes the OSSLT or enrols in the OSSLC
  • take into consideration all accommodations included in the student’s IEP that are also permitted by this policy and by the EQAO (see Permitted accommodations subsection) and be consistent with regular classroom practice, including assessments
  • be clearly communicated in writing to the parent(s)/guardian(s) or directly to the adult student before the student takes the OSSLT or enrols in the OSSLC
  • be recorded, with all pertinent relevant details, in the e-assessment system for students writing the OSSLT
(1b) Permitted accommodations

Required accommodations for the OSSLT and OSSLC may take several forms. In each case, the accommodation must be specified in the student’s IEP.

Accommodations permitted for students with an IEP by the EQAO for the OSSLT include:

  • adjustments to the format of the test (for example, alternative versions of the test)
  • adjustments to the format of responses

Clarification of instructions for both the reading and the writing components of the OSSLT is permitted for every student before the test begins. Such clarification is not considered an accommodation.

If an accommodation described in a student’s IEP is permitted by the EQAO, the principal must ensure the accommodation is available to the student during the OSSLT.

If an accommodation that might be necessary is not included in the student’s IEP or if the student doesn’t have an IEP but might need an accommodation, they may submit a request for special consideration to the supervisory officer. Upon request, the EQAO will also consider other accommodations.

(1c) Requests for special consideration of accommodations

Permitted Accommodations listed in the EQAO Guide

When a parent, adult student or principal identifies the need for an accommodation that is listed in the EQAO User Guide for Administration of the Ontario Secondary School Literacy Test, one of the following procedures applies:

  • If the accommodation is not described in the student’s IEP, the parent, adult student or principal may submit a request for consideration to the appropriate supervisory officer. The decision of the supervisory officer is final.
  • If the student does not have an IEP because they recently transferred into the school from another jurisdiction, the parent, adult student or principal may make a request for accommodation to the appropriate supervisory officer. The decision of the supervisory officer is final.
  • If a student who would not normally require accommodations requires one or more in order to take the test or course because of temporary circumstances, the principal may grant permission for use of any appropriate accommodations as permitted in the EQAO Guide. If the principal determines it is not possible to provide an accommodation, a deferral should be considered. If the parent or adult student disagrees with the principal’s decision, they may make an appeal to the appropriate supervisory officer. The decision of the supervisory officer is final.

For students in provincial and demonstration schools, requests for accommodation must be made to the appropriate superintendent. The decision of the superintendent is final.

For students in approved education programs in care or treatment, custody and correctional facilities, requests for accommodation must be made to the appropriate supervisory officer. The decision of the supervisory officer is final.

For students in ministry-inspected private schools and inspected First Nation/federally operated schools, requests for accommodation must be made to info@eqao.com.

Accommodations That Are NOT Listed in the EQAO Guide

A parent, adult student or principal can submit a request for consideration to EQAO when they identify a need for an accommodation that meets certain criteria. The decision of EQAO is final. To be considered, an accommodation must meet all of the following criteria:

(1d) Human resources required for the implementation of accommodations during the OSSLT

Any person who is engaged to support the accommodations of one or more students and is not a teacher must work under the direct supervision of a teacher. Only adult persons who are not relatives of students writing the OSSLT may assist during the test. These individuals should be given training and guidelines outlined in the EQAO User Guide for the Administration of the Ontario Secondary School Literacy Test (OSSLT).

  • The role of individuals who support accommodations for students with special education needs is to ensure those students are properly supervised during the administration of the test and the accommodations are appropriately implemented.
  • These individuals shall not provide students with any assistance that would compromise the validity of the test. That is, they shall not provide assistance that helps students understand the questions or formulate their answers, or give any instructions or suggestions (for example, about pacing their work) not given to every student writing the test.
  • These individuals can provide prompts for students who are off task. A prompt can be a tap on the desk or a verbal signal (e.g., a word or phrase) to draw the student’s attention back to the test. Prompts do not include clarification, explanation or translation or any part of the test and may not be used to draw the student’s attention to a specific part of the OSSLT.
  • Students are permitted to work with a scribe if they have this accommodation listed in their IEP or have an approved special consideration. School administrators are responsible for reviewing the guidelines with individuals who will be acting as scribes and follow the Guidelines for scribes as outlined in the EQAO User Guide.

2. Special Provisions for English-language Learners pertaining to the Ontario Secondary School Literacy Test

Special provisions are adjustments to the setting and/or timing of the writing of OSSLT for English language learners. (For a definition of English language learners, see section 3.1). These provisions do not affect the validity or reliability of the test.

Special provisions for English language learners may be provided for the test if the principal believes them to be in the best educational interest of the student. Decisions about special provisions must:

  • be made on an individual student basis
  • be made by the principal in consultation with the student, their parent(s)/guardian(s) (if the student is under the age of 18) and appropriate staff
  • be made before the student takes the OSSLT
  • conform to the permitted special provisions outlined by EQAO in the User Guide for the Administration of the Ontario Secondary School Literacy Test (OSSLT)
  • be clearly communicated in writing to the parent(s)/guardian(s) or directly to the adult student before the student writes the test
  • be recorded, with all relevant details, in the EQAO e-assessment system
3. Deferrals of the OSSLT

Deferrals are intended for students who are working toward an OSSD may be eligible for deferrals of the OSSLT under certain circumstances. Eligible students may include those who:

  • have an IEP and would not be able to take the test even if all accommodations were provided
  • are English language learners and have not yet acquired a high enough level of proficiency in English to take the test
  • have not successfully acquired the reading and writing skills appropriate to Grade 9
  • are unable to write the test at the scheduled time(s) because of illnessfootnote 4, injury or other extenuating circumstances
  • are new to the school and cannot be provided with the appropriate accommodations in time

In all cases, documentation must be submitted to the principal of the school.

Deferrals to postpone the writing of the OSSLT until the following school year for students who are working toward an Ontario Secondary School Diploma (OSSD), are granted before the test, on an individual basis. Generally, deferrals are requested in writing by a parent (or adult student) or the school, in consultation with both parties. In some cases, a principal may also raise the possibility of a deferral with the parent or adult student.

The principal will make the decision in consultation with the parent or adult student and appropriate school staff. In cases of disagreement, the parent or adult student may ask the appropriate supervisory officer to review the matter. The decision of the supervisory officer is final.

Students who are granted a deferral will write the test at a scheduled sitting in the next school year, as prescribed by the EQAO. If an additional deferral is required, the principal must review the request again with the parent or adult student and appropriate school staff. While there is no limit on the number of deferrals that may be granted, the parent or adult student must be advised that each deferral reduces the number of opportunities to take the test. They must also be reminded that successful completion of the test, the OSSLC or an adjudication process is an OSSD requirement. A deferral is not considered an opportunity to write.

Students should be encouraged to write the test to enable the school to better understand their strengths and needs and develop an appropriate program or other forms of support to prepare them for their next attempt.

The decision to defer must be entered, with all pertinent details, in the EQAO e-assessment system. All documentation related to a decision must be kept in the student’s Ontario Student Record.

4. Exemptions from the literacy graduation requirement

To be eligible for an exemption from the literacy graduation requirement, a student must have an IEP. The IEP must include documentation to support an exemption and a clear indication that the student is not working toward an OSSD. Both parental consent and the approval of the principal are required for an exemption.

Exemptions are provided on an individual basis, as part of the IEP process. The principal decides on the basis of the student’s learning expectations and in consultation with the parent or adult student, whether the student is working toward the OSSD. If it is decided that the student is not working toward the OSSD, the principal decides, again in consultation with the parent or adult student, whether to grant the student an exemption from writing the OSSLT or taking the OSSLC. The final decision must be communicated in writing to the parent or adult student as part of the IEP development process.

In cases of disagreement:

  • If the principal decides the student should be exempted from writing the test or taking the course, but the parent or adult student disagrees with this decision, the student must be allowed to write the test or take the course.
  • If the principal decides the student should write the test or take the course, but the parent or adult student disagrees with this decision, the matter will be referred to the appropriate supervisory officer. The supervisory officer’s decision is final.

Where it is determined that an exemption does not apply and that a student who has an IEP and is receiving a special education program and/or services is to take the test or course, the principal must ensure the student has a fair and equal opportunity to successfully complete the test or course. Necessary accommodations are to be provided in accordance with the policies outlined in this section, section 6.1.3.1, and section 6.1.3.2. If the learning expectations in a student’s IEP are revised at any point and the student begins to work toward the OSSD, the student must successfully complete the OSSLT, the OSSLC or the adjudication process to be eligible for the OSSD.

All documentation related to the decision to grant an exemption from taking the test or course must be kept in the student’s Ontario Student Record.

Principals may substitute up to three compulsory credits with courses from other subject areas specified in the list of compulsory credit requirements (outlined in section 6.1.1) in order to provide the flexibility to tailor an individual student’s program to the student’s needs and to support their progress through secondary school. Substitutions should be made to promote and enhance student learning or to respond to special needs or interests.

Two half-credit courses may be substituted for one compulsory credit requirement, or one full-credit course may be substituted for the two compulsory half-credit requirements of civics and citizenship and career studies. Each of these substitutions is considered a single substitution.

Substitutions may be requested by parent(s)/guardian(s), an adult student or initiated by the principal. In consultation with parent(s)/guardian(s) or an adult student and appropriate staff, the principal will determine whether a substitution should be made. If a parent or adult student disagrees with the decision, they may ask the appropriate supervisory officer to review the matter.

The following limitations apply to substitutions for compulsory credits:

  • English as a second language and English literacy development courses may not be used to substitute for compulsory credits. They may be used, however, to meet the compulsory credit requirements for three English credits (see section 6.1.1).
  • No more than one learning strategies course from the guidance and career education curriculum may be substituted for a compulsory credit requirement.
  • Credits earned for cooperative education courses may not be substituted for compulsory credit requirements.
  • College-delivered dual credit courses may not be substituted for compulsory credit requirements.
  • A locally developed compulsory credit course may not be substituted for a compulsory credit. These courses may be used only to meet the compulsory credit requirements they were designed to meet (see section 7.3.1).
  • Senior English and math are compulsory for mature students per PPM 132: Prior Learning Assessment and Recognition for Mature Students – Revised Mandatory Requirements ” (see section 7.2.4.2)

All substitutions will be noted on the student’s Ontario Student Transcript.

6.3 Ontario Secondary School Certificate

The Ontario Secondary School Certificate (OSSC) will be granted, on request, to students who are leaving secondary school upon reaching the age of 18 without having met the requirements for the Ontario Secondary School Diploma. To be granted an OSSC, a student must have earned a minimum of 14 credits, distributed as follows:

  • 7 compulsory credits
    • 2 credits in English
    • 1 credit in mathematics
    • 1 credit in science
    • 1 credit in Canadian history or Canadian geography
    • 1 credit in health and physical education
    • 1 credit in the arts, computer studies or technological education
  • 7 optional credits, selected by the student from available courses

The provisions for making substitutions for compulsory credits described in section 6.2 also apply to the OSSC.

6.4 Certificate of Accomplishment

Students who are leaving secondary school upon reaching the age of 18 without having met the requirements for the Ontario Secondary School Diploma or the Ontario Secondary School Certificate may be granted a Certificate of Accomplishment. This certificate may be a useful way to recognize achievement for students who plan to take certain kinds of further training or find employment directly after leaving school. The Certificate of Accomplishment is to be accompanied by the student’s Ontario Student Transcript. For students who have an Individual Education Plan, a copy of the plan may also be included.

Students who return to school to complete additional credit and non-credit courses (including courses with modified or alternative expectations in special education programs) will have their transcript updated accordingly. However, they will not be issued a new Certificate of Accomplishment. An Ontario Secondary School Diploma or Ontario Secondary School Certificate will be granted when the student has fulfilled the appropriate requirements.

6.5 Granting of diplomas and certificates

On the recommendation of the principal, the Minister of Education grants diplomas and certificates at any time during the year to students who have successfully completed the necessary requirements.

If a student completes the requirements through private study, night school, summer school or online learning, the diploma or certificate will be issued by the principal of the school that holds the student’s Ontario Student Record when the final credit is earned. If the final credit is earned through the Independent Learning Centre (see section 10.4), the student may choose to have the diploma or certificate issued by the director of the Independent Learning Centre or the principal of the school last attended. The person issuing the diploma or certificate will submit the necessary report to the Ministry of Education.

6.6 Ontario Scholar Program

PPM 53: Ontario Scholar program

provides direction to school boards and schools concerning the designation of a student as an Ontario Scholar.

  • earned an Ontario Secondary School Diploma in the current or previous school year
