Mature Student

Get the credits you’ve always wanted.

We are authorized to grant credits by the Ontario Ministry of Education BSID #667186

To proceed with admission into OES as a mature student please read the scenario that fits your circumstance and follow those steps accordingly:

Purchase the PLAR here to begin the process for your Mature Student Assessment.

You qualify as a mature student in Ontario if you are:

  • at least 18 years old on or before December 31 of the school year;
  • previously enrolled in a secondary school credit program for the purpose of obtaining an OSSD (or a credit);
  • have been out of school for a period of at least one year before returning as an adult.

You may be eligible to earn credits through PLAR if any one of the following applies:

  • You started Grade 9 in Ontario in 1999 or later, but you did not earn the Ontario Secondary School Diploma (OSSD).
  • You have earned senior credits (grades 11 and 12) in English and Math but are missing junior credits (grades 9 and 10) in compulsory subject areas.
  • You completed some or all of your high school education outside Ontario or Canada and you have academic documents to indicate what educational level you completed.
  • You attended high school outside Ontario or Canada but you do not have any documents to show what educational level you have completed.

Through PLAR, it may be possible for an adult student to earn credits towards an OSSD faster than you think! Read more below. 

Completed some or all of high school outside of Ontario, or Have completed some or all College or University education outside of Ontario.

Please read about the Equivalency Process (assessment of documents) and Challenge Process (completion of assessments) and then proceed below:

  1. Purchase the PLAR (Prior Learning and Recognition) service you are interested in. The fee for the PLAR Equivalency is $100.00 + tax while the PLAR Challenge is $250.00 + tax.
  2. Complete the registration form that you will receive in your email after your purchase.
  3. Complete either the Equivalency Form or Challenge Form based on the PLAR you would like OES to complete.
  4. Email a scanned copy of Government Issued ID to
  5. Required documents as per the forms above: As it applies, please email a scanned copy of all your academic records, transcripts, diplomas, certificates and resume along with any other experience you have gained to — this will help us determine how many equivalency credits you may be granted and/or whether you are eligible for the challenge process.
  6. If you are applying outside the Province of Ontario, you will need to arrange for a proctor (see our FAQ for more information) to oversee our mandatory English Proficiency Assessment.

During this process an Ontario Education Number (OEN) will be assigned to you and an Ontario Student Record (OSR) will be created and maintained in our office. The results of the PLAR will outline the number of credits you have been granted (out of 30) and the stream you have been placed in outlining the types of courses you will be eligible to complete going forward.

Earned some high school credits in Ontario or completed all of them (ie. 30 credits) and would like to enroll into a University-level course but do not have the prerequisite course or would simply like to complete your high school diploma.

If you are a mature student and know the course you would like to register for and are confident that you have the prerequisite, you are welcome to go ahead to the courses page and enroll in the course you desire. Proof of prerequisite in the form of a transcript, report card or credit summary will be required.

If you would like to earn the credit for a course ie. Challenge the credit based on reasonable evidence from past experience and/or prior knowledge between now and the time you last left high school, you will be entered into the Challenge Process

Before entering this process you will first need to answer self-guided questions on the Challenge Process page under the ‘Eligibility’ section. Once you are sure you are eligible please purchase the PLAR (Prior Learning and Recognition) for a cost of $250.00 + tax and please go ahead and complete the Challenge Form and submit it to after your PLAR purchase.

Based on the results of the assessment and the documentation provided to supplement your circumstance, the Principal may be able to place you into the credit course or grant you the credit with a percentage grade showing on your transcript — this is strictly on a case by case basis. For more information please email or read more about the Challenge Process.

Depending on your circumstance and completion of some high school credits, the Principal would be able to grant you up to 16 Grade 9 and 10 credits. We would be able to do this through you providing us with:

a) previous academic records, or

b) transcripts and completion of individual assessments, or

(c) completion of individual assessments.

If mature students have completed training programs or military service programs they may qualify for equivalency credits or have the ability to challenge a course for credit. Up to 16 Grade 9 and 10 credits may be granted to a mature student at the discretion of the principal following individual assessment.

For Grade 11 and 12 credits:

Mature students may earn 10 of the 14 remaining Grade 11 and 12 credits needed to meet diploma requirements in three ways:

(1) they may demonstrate achievement of the required secondary school curriculum expectations and receive credit through the challenge process i.e. Completing an assessment for that grade level;

The challenge process is the process whereby students’ prior learning is assessed for the purpose of granting credit for a course developed from a provincial curriculum policy document.

(2) they may present education and/or training credentials for assessment through the equivalency process;

The equivalency process involves the assessment of credentials from other jurisdictions for courses already complete.


(3) they may take the courses.

It should be noted that Levels 2 and 3 in both classical languages and international languages are equivalent to Grades 11 and 12, respectively, and that Levels 4 and 5 in Native languages are equivalent to Grades 11 and 12, respectively.

Mature students must earn a minimum of 4 Grade 11 and 12 credits by taking the course at a secondary school such as OES. Mature students who have previously accumulated 26 or more credits towards the diploma must successfully complete the required number of courses to bring their total number of credits up to 30 before they will be eligible to receive the OSSD.
