The summer slump-teachers agree it's the worst thing about summer vacation. Numerous studies have shown that many students, especially low-income children, backslide in reading ability over summer vacation.
Some lose over three months worth of ability. This means that a child who finished second grade reading at grade level could start third grade reading at the level he or she was at back in March. To add insult to injury, more affluent students with greater access to books, reading programs, and enrichment activities can increase their ability over the summer, further widening the gap between low and high socioeconomic status children.
