They sound like workout sessions at a gym, but "flex periods" are fast becoming a scheduling strategy among Northern Virginia high schools that want to offer students remediation or enrichment during the school day rather than before or after classes.
High schools in Fairfax, Prince William and Loudoun counties have been inserting these chunks of time -- from 40 to 90 minutes, depending on the school -- for several years, often to reduce after-school tutoring costs but also to raise achievement in the era of the federal No Child Left Behind law.
The program varies among schools, but the premise is similar: Between regular courses, students are assigned to a flex classroom to review material or work independently. Flex time can also be used for attending schoolwide events. And if a student needs help from a teacher in another part of the building, he or she can get a pass and visit the teacher during flex time.
