Who is a Mature Student?
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 and also from this Ministry Memoranda which we use as a guide.
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 then proceed below:
- Purchase the PLAR (Prior Learning and Recognition) service you are interested in. The fee for the PLAR Equivalency is $250.00.
- Complete the registration form that you will receive in your email after your purchase.
- Complete the Equivalency Form
- Review the Ministry Memoranda so you understand what is expected from you and what may apply to you
- Email a scanned copy of Government Issued ID to email@example.com
- 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 firstname.lastname@example.org — this will help us determine how many equivalency credits you may be granted and/or whether you are eligible for the challenge process.
- 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 or College 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 learn more on our “How Does it Work?” 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 have any questions or would like to know more about course enrolment such as waiving prerequisites please email email@example.com
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 two ways:
(1) 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.
(2) 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.

I was given a yearly time period to complete a course and finished within 3-4 months. Your assigned teacher isn't obligated to delegate you, but just like any field of learning. There're expectations and deadlines.Raymond Chan4/04/2021
My son recently completed Challenge and Change, a grade 12 social science course from overseas. His experience from registration, through to course work, exam competition and facilitating his grade to his transcript was exceptional, responsive, and professional. His teacher Mara was more engaged than many of his previous in-person teachers. Thank you!!!Jody Young3/05/2021

OES is a highly professional online post secondary school which enables anyone to be able to earn high school credits or even upgrade high school marks. The administration, staff and teachers are all extremely helpful and supportive. I would absolutely recommend them to anyone!!!
Thank you OES!!! 😄Linda Sirota1/09/2021
Amazing school experience where the teachers are there to help facilitate learning and excellence, not to put their students down, like many teachers do. I re-took grade 11 university functions and received a much better education and final grade than my experience in public schooling in Southern Ontario. I would highly recommend this if you are organized and can meet your own deadlines.Derek Ford12/07/2020
One of the best school and experience I had.
Easy and comfortable timeline, professional teachers and principal, they did help me a lot to pass everything and explaining everything nice and easy to me regarding my deadline. They do have a 24 hour tutors that can help you to explain at any time I like it I don’t know what to say more but it’s one of the best school.
Thank youAL obaidi12/02/2020
Ontario eSecondary School is by far the best online learning academy in Ontario. My teacher was very great as he was easily accessible, had very fast response times, and was extremely friendly. He even had the chance to do our live meeting on Thanksgiving Monday! The course content for the class I took was great, and will be very beneficial for post-secondary learning. It was amazing that they provided free online tutoring for students, that feature really stood out to me when selecting OES for this course. You will not regret taking a course here!Julia Mesburis11/08/2020

I took a high school course with his institution in order to qualify for the college program I wanted to take.
The administrative staff and instructors were all very congenial and swift in their responses. Access to tutoring is phenomenal and I have nothing but praise for my experience with this educational provider.

I completed a Grade 11 University Physics class with OES which was required for a college program that I was looking to pursue.
My experience was fantastic; the opportunity that OES gives you to learn at your own pace is really great! The tools material provided to assist you in learning are more than adequate. They provide a free online tutoring service which is extremely helpful in a pinch!
Everyone, including my teacher and the administration, was so helpful especially Mara (Program Admin)! She was always available to assist me with any questions/requests I had. Thank you OES!R_19968/24/2020
