Why do some colleges require all testing to be reported?

Another exception is athletic recruiting for highly selective schools. For some sports, the main recruiting season is the sophomore year. Being able to have a firm ACT/SAT score will go a long way in bolstering the confidence of a coach that a potential athlete will be able to meet the minimum Academic Index required by the school, and requires the student/athlete to achieve that score at an early age.

One kid we knew was recruited to an Ivy, and was told she needed a 33 to get a likely letter. Despite multiple attempts, she was not able to get the score, and ended up playing someplace else.
