Usefulness of ACT and SAT scores

The national average ACT score is 20.7, our state average is 18.9, and the average score at our local district is 21.0.  As far as college admission is concerned, for the vast majority of high school students and colleges the standard test scores play very little role.

The test scores are most valuable when applying for merit scholarships. The question is how many students in this forum are taking advantage of their perfect or close to perfect scores?
