Grade Inflation Made Testing Matter More, Not Less, Here’s Why
The test-optional movement was built on a specific premise: standardized tests were an unnecessary barrier, and transcripts, grades, and holistic review could differentiate applicants just as effectively without them. That premise is now being tested directly against outcome data, and a growing number of the most selective institutions in the country have concluded it doesn’t hold.
Dartmouth’s own institutional research found standardized test scores were a stronger predictor of academic success than high school GPA, particularly for first-generation and low-income applicants. Yale’s admissions office found that students who chose not to submit scores were, in the dean’s own account, unknowingly hurting their own admission odds. Once the office examined the numbers directly, students without submitted scores were being admitted at roughly a third of the rate of students who submitted them.
For the 2026-2027 cycle, Harvard, Yale, Dartmouth, Brown, Cornell, MIT, Caltech, Stanford, and Penn all require test scores again. Columbia, the last Ivy holding a permanent test-optional commitment, announced in June it will require testing starting with the 2027-2028 cycle.
The measurement problem underneath the policy reversal
The reasoning driving this shift is largely a validity problem, not an ideological one. More than half of college applicants nationally now report a GPA of A- or better. When the majority of a candidate pool clusters at the top of the grading scale, GPA stops functioning as an effective differentiating instrument, regardless of how rigorously any individual school or teacher grades. This is a textbook measurement compression problem: as scores compress toward a ceiling, their discriminating power collapses, and institutions lose the ability to use them for the comparative function they were originally designed for.
Test scores, whatever their other limitations, haven’t experienced the same compression, which is precisely why several institutions are reporting they retain more predictive value in a landscape where transcripts increasingly don’t.
What this means for counseling offices, concretely
This shift has direct implications for how students are advised, and the strategy is more nuanced than “always submit” or “never submit.” The data suggests a threshold-based approach: students whose scores fall within or above a target institution’s published middle 50% range benefit from submitting, even at schools that don’t formally require it. Students whose scores fall well below that range are often better served relying on the rest of their application.
Counseling offices that haven’t updated testing guidance to reflect this reversal risk giving students outdated advice built on a policy landscape that no longer matches institutional practice at a meaningful share of target schools. Common App data shows applicants submitting scores rose 11% year over year this cycle, evidence that families and students are already recalibrating, with or without formal guidance from their school.
The broader pattern this signals
Grade inflation and test-score reinstatement are, together, a case study in what happens when a single measurement instrument becomes compressed and institutions have to identify or restore an alternative. It’s a pattern worth watching beyond testing specifically: any measurement system under sustained upward pressure eventually loses its differentiating function, and the response is rarely to eliminate measurement, but to diversify or restore the instruments doing the actual work.
Where we come in
We help partner institutions build testing and application strategy guidance that reflects current institutional practice rather than outdated test-optional assumptions, so students aren’t navigating this shift without informed support. If your counseling office is reassessing testing guidance for this cycle, we’d welcome that conversation. Learn more about partnering with us.
Testing didn’t become more important because standardized tests improved. It became more important because grades stopped being able to do the job alone.
