Argument: Year-round schooling requires less review of past materials
Don Heinzman. "Year-round schooling has advantages". Hometown Source. - Students start school Aug. 1, and have nine-week sessions and three-week vacation breaks, as well as five weeks off in the summer.
When the students return for class, they spend little time reviewing subject matter and are ready for new material. The different break times give parents an opportunity to go on vacation other than during the summer.
