When students don’t practice academic skills over the summer, they don’t always retain what they’ve learned during the previous school year. 

On average, students lose approximately two months of learning in math skills over the summer break. 

Students from lower socio-economic backgrounds also lose an average of two months in reading achievement over the summer. 

Approximately two-thirds of the achievement gap for lower socio-economic 

9th graders can be attributed to summer learning loss. 

By the end of fifth grade, disadvantaged children are nearly three grade levels.
