Maturity & Equivalency Credits

About Maturity and Equivalency Credits

Maturity and Equivalency Credits provide a quicker way for adults to earn credits towards an Ontario Secondary School Diploma (OSSD)

Students may be recommended for up to 12 maturity credits and may receive equivalent credit allowances for certain courses and training programs outside of secondary school. For example:

  • successful completion of courses not usually considered secondary school subjects (this could be certification or designation in a specific program that required a minimum of 110 hours of instruction or training)
  • successful completion of each period of an apprenticeship program (for example, electrician, hairdresser, or mechanic).


If you started high school in Ontario before September 1999, your previous work and life experiences may qualify you for “maturity credits”. This only applies to students graduating under the old diploma requirements (that is, if you started high school before September 1999).

You started Grade 9 in Ontario in 1999 or later, but you did not earn the Ontario Secondary School Diploma,  please view M.P.L.A.R  

Please note that in order to be granted a diploma, a mature student must still complete a minimum of four Grade 11 or Grade 12 credits after becoming a mature student. These credits must include a senior English.
