The GRE has been evolving over the last few years — the most significant change would be the move to computer-adaptive test taking — in order to make the test more relevant, i.e. more predictive of future success. Not so long ago, the GRE contained vocabulary, critical reading, grammar, mathematics (all very similar to the SAT) and analytical and logical reasoning (very similar to the LSAT). Critics argued the GRE needed a writing component, so they switched out the multiple choice of logical and analytical reasoning and replaced them with two essays involving analysis of, and making, an argument. More recently, the GRE added new question types for passage completions (same model as sentence completions except spread over a paragraph) and student-produced response in math.
The latest change, however, represents a real shift in structure. The GRE wants to gauge more intangible qualities like communication skills and ethics, so it has created the “Personal Potential Index” — a numerical index that supervisors and educators complete about the test taker. On paper, this seems like a good idea. But this mechanism suffers from two flaws. First, the index is not from the student taking the test but others who watch his or her behavior. We already have letters of recommendation that do this very task. A standardized test should test the student, not his or her associates. Second, by relying on educators and supervisors, the GRE introduces a form of index inflation — how many educators or supervisors will tank their own? How likely is it they will be extra glowing in their reports?
A few years ago, I wrote a law review article analyzing the LSAT. I proposed expanding its scope to include traits like communication skills, negotiation strategies, problem solving abilities and ethical dilemmas. But the type of addition I proposed involved an additional test completed by the applicant, not a reporting index. I applaud the GRE for focusing on intangibles, but suggest they move more toward a student-produced measure of these skills.
The larger question becomes one of fit — does the GRE serve the right goals in helping graduate schools make good admission choices? Certainly, the GRE contains a broad measure of basic skills. But the degree of difficulty between the GRE and SAT is not that different, and four years of college should create a larger divide. The writing component has helped significantly add an analytical argument dimension. But we are talking about future professors, psychologists — future PhD holders. Should we not expect more at the entry point? At least as much as we demand of future lawyers and doctors? Or is there some qualitative difference between doctoral degrees? I think graduate excellence is graduate excellence, and the GRE could do more to measure those skills and make a statement that we expect more of any future PhD candidate.
