College Board (SAT)
American College Testing (ACT)
The Princeton Review reports that most colleges weight the SAT and ACT at about 40% of the college admittance process.
Many students with documented learning disabilities will significantly benefit from securing testing accommodations on the SAT or ACT (i.e., extended time). The time advantage is designed to provide students with learning challenges equal opportunity.
Test makers are not allowed to inform colleges that a student received extended time on the SAT and ACT exams; thus, the colleges your child applies to will treat their scores in the same manner as someone who had not received extended time.
On the SAT, extended time benefits some, but not all students. While the ACT allows extended time for students (over multiple days) to self-pace through the test, the SAT mandates students to remain in each discrete section until the time is exhausted.
