It may sound ironic, but the summer months are some of the most important in the school year. You read that correctly: the summer months play a vital role in a student's academic momentum and growth. According to data collected in 2020 through the MAP Growth assessments, students in 3rd to 5th grade lose an average of 20 percent of their school-year gains in reading over the summer months. Young elementary students are also, and perhaps even more so, at risk of suffering the "summer slide" because they are earlier in the development of their academic skills.
