Even though it became law way back in 2012, people are still debating over whether or not Proficiency Based learning is right for Maine schools.

According to Maine.gov, Proficiency-based education refers to any system of academic instruction, assessment, grading and reporting that is based on students demonstrating mastery of the knowledge and skills they are expected to learn before they progress to the next lesson, get promoted to the next grade level or receive a diploma.

People who defend it say that it's much more personal for the students, and allows teachers to customize a student's learning plan.

Other say that it lowers the bar for kids, and suspect there may be outside influence with ulterior motives at play.

WMTW's Kathleen Jordan takes a deeper look at the issue, today starting at 4 on Channel 8 WMTW.
