BAY CITY, Mich. - Bay City Public Schools will move to a trimester system in its high schools starting in 2009-2010, according to The Bay City Times.

The schools will move to three 12-week terms, as opposed to the current two 18-week semesters. The switch will allow students to take 15 classes per year, instead of the standard 12 under the semester system. The district decided to change schedules as an adjustment to the new state graduation requirements, which leave little time for elective courses or for making up failed courses, The Times reported.
