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.
