According to the American Bar Association (ABA), law schools are no longer required to use the Law School Admission Test (LSAT) to be accredited by the ABA. That doesn’t mean that you don’t need to take a standardized test to apply to law school, it simply means that law schools can choose which tests they’ll accept because they won’t be required to use the LSAT.
The College Board couldn’t be more pleased with this decision because most law schools will probably accept the GRE, which is offered by the College Board. When looking to see what tests offer the best predictor of success in law school, most find that the GRE and the LSAT result in equal predictive values.
So, if you’re law school bound, you now have options. Like high school students who can take the SAT or ACT, law school applicants who didn’t do well with the LSAT may do better with the GRE.
