Prior Learning Assessment and Recognition (PLAR) refers to the structured assessment and granting of academic credits, allowing students to receive credit for learning they acquired before. This learning encompasses both formal and informal knowledge and skills acquired beyond secondary school. Students can undergo an evaluation of their knowledge and skills, aligning them with the standards set in provincial curriculum policies, to earn credits for their high school diploma. The PLAR process comprises two main parts: "challenge" and "equivalency."

The "challenge" process is the process whereby students' prior learning is assessed for the purpose of granting credit for a Grade 10, 11, or 12 course developed from a provincial curriculum policy document published in 1999 or later.

The "equivalency" process is the process of assessing credentials from other jurisdictions.
