The criteria for admissions at colleges and universities continue to evolve with Stanford and Princeton joining Harvard and Yale in dropping the required writing test for both the SAT and the ACT and replacing it with the submission of a graded writing sample. These schools hope to make entry easier for low and middle income and minority students who may not test well. Portfolios of work, video essays and proof of commitment to the community are now opening doors for students whose test scores prevented them from attending some of the country's most elite schools.
