A proposal in the Legislature would force kids to enroll in summer school if they score less than proficient on statewide tests. Right now, it’s optional. School officials say for a lot of kids, summer school isn’t punitive, but enriching. Especially in the elementary grades, students are attending summer school classes to help get ahead in reading and math. Summer school classes are also useful because they keep the kids thinking all throughout the summer when many of the materials learned during the normal school year are often forgotten.
