Is America's achievement gap crisis caused by long summer vacations? "In lower income neighborhoods, kids forget anywhere from two-and-a-half to three-and-a-half months of what they learned during the school year over the summer, while their middle-class peers break even or even make gains," says Karim Abouelnaga, CEO of Practice Makes Perfect. This startling statistic is why he started a different kind of summer school, one based on a chain of near-peer mentors, where kids are connected with college students and college students are connected with teaching professionals. "This model, where everyone is sort of a participant but also a beneficiary, creates this win-win-win situation for everyone, making summer school a lot more fun and exciting." Why do some eighth grader students only have a fourth grade reading level? Theoretically speaking, they’ve only been in school for half the time, says Abouelnaga.
