The ACT and the SAT have becoming optional at so many schools, I don't think we'll be seeing them have much impact moving forward. The latest statistic I saw is that over 80% of schools are now test optional for admissions, as is the state university where I teach. As a department chair, I get the weekly admissions and enrollment reports. For this year's incoming class, 58.3% did not submit test scores. Last year was 30%.

There is mixed data on whether test scores predict college success -- check the source, because there is "pro test" data from studies that were funded by the the test companies themselves. Other data indicate a stronger correlation with HS GPA.
