AUGUSTA, Maine (AP)   Maine lawmakers are set to consider delaying a system aimed at making sure high school graduates are proficient in key subject areas.

The Legislature’s education and cultural affairs committee on Wednesday tabled a bill to delay the system for another year. Lawmakers say they’ll keep working on the legislation.

A 2012 Maine law says that by 2018, all graduating students should show proficiency in eight subjects. Maine and Vermont were the only states with such systems as of last year.

Maine never passed any regulations to clarify what’s expected of schools. The state’s education department is working on such rules.

Across the state, districts have instead been moving ahead on their own to meet a requirement that begins with the class of 2021.
