As many of us have experienced, standardized testing is generally used as a predictor for future success. The two major tests that are generally regarded as two of the most important tests you will ever take are the ACT and SAT for college admissions. Although these tests do show some measure of cognitive ability, they do not accurately predict academic success in higher education. According to a study done by Rebecca Zwick of the Educational Testing Service and Igor Himelfarb of UC Santa Barbra, there are a lot of different problems with only using these types of tests for admissions.
One of the main problems stated in the study is that your socioeconomic status plays a large role in how well you do on these tests. This is caused by many different variables. A main one is the availability of resources and quality of schooling throughout the different class levels. This caused an over prediction of first year GPA for African-American and Latino students. This systematic over prediction helps to show that the SAT does not capture all of the necessary factors that go into predicting first year GPA in colleges.
With these problems in the standardized tests, I believe that more emphasis should be placed on HSGPA, which showed throughout this study to have predicted first year GPA with a correlation between .59-.89. If the admissions of college are more based on grades rather than a test, students would have a higher rate of success in their first years.
