Maturity Prior Learning Assessment (M.P.L.A.R.)

This program is designed for students who are 18 years of age or more,  have been out of school for at least 1 year, started Grade 9 in Ontario in 1999 or later, but did not earn the Ontario Secondary School Diploma (OSSD).

If you started high school in Ontario before September 1999, please see “Maturity Credits”.

What is M.P.L.A.R.  ?

Maturity Prior Learning Assessment and Recognition provides a quicker way for Mature Students to earn credits towards an Ontario Secondary School Diploma (OSSD). Learners may earn up to 16 junior (grades 9 and 10) credits and/or 10 senior (grades 11 and 12) credits through an assessment of transcripts and/or the completion of assessments.

The number of credits that may be earned is determined by several factors including the number and type of courses previously taken in Ontario or elsewhere.
