GPA and Standardized tests tell different things about a student.
GPA signals that a student is able to take care of everyday school responsibilities (studying, participating, showing up, turning in required work, studying for tests. etc). Standardized tests tell you how the student understands what is being taught.
If a school's general requirememnts are high SAT/ACT scores that means that is the level that the courses are taught on. The higher the SAT required, the more difficult the school is.
In recruiting, coaches very rarely are able to find the right combination of talent, SAT scores and GPA, so they make concessions. For example my son had very high GPA but lower SAT requirement for admissions. His high GPA indicated he was organized, responsible in the classroom and good time management. But he often required help of tutors to help him understand what was presented in class. While some of his friends had much GPA but very high SAT, they required less assistance in their classwork.
A student with lower GPA and lower test results, these days, will most likely have more difficulty obtaining scholarships at D1 schools.
