The University of California system is facing a quiet instructional collapse in its most competitive majors. For five years, the university operated under the absolute certainty that eliminating standardized testing would democratize higher education without harming academic standards.
The data tells a completely different story.
More than 600 STEM faculty members across the UC system have signed an open letter addressed to the Board of Regents, the Office of the President, and the people of California. Their demand is simple. They want a immediate return to mandatory standardized testing for all science, technology, engineering, and math applicants. The reasons detailed in their petition are brutal.
According to an internal UC San Diego Senate-Administration Workgroup report, the number of incoming freshmen possessing math skills below the high-school level has surged nearly thirtyfold over the past five years. Worse, 70 percent of those underprepared students are functioning at a middle school math level. At UC Berkeley, mathematical diagnostic testing revealed that 20 to 30 percent of first-semester calculus students lacked the foundational concepts required to pass the course.
This is not a minor adjustment period. It is a structural failure. By refusing to look at SAT or ACT math scores, the UC system did not eliminate achievement gaps. It merely hid them until the students walked into a university lecture hall.
The Blind Admissions Disaster
When the UC system shifted to a permanent test-blind admissions policy, administrators promised that holistic reviews of high school grade point averages, extracurricular activities, and personal essays would provide a clearer picture of a student's potential.
They overlooked the rapid decay of the American high school grading system.
Grade inflation has turned the high school transcript into an unreliable metric. When every high-achieving applicant possesses a 4.0 GPA, the grade ceases to function as a differentiator. It provides no information about whether a student's straight-A average in calculus represents genuine mastery or a lenient teacher.
Simultaneously, the college essay has lost its utility as an authentic measure of student capability. The widespread availability of generative artificial intelligence and high-priced admissions consultants means that essays are frequently optimized by external forces. The admissions office receives a polished, flawless portfolio that reflects resource access rather than individual readiness.
Professors are left to manage the consequences. University faculty who once spent their time teaching advanced engineering concepts are now forced to halt lectures to explain fraction division, basic algebra, and fundamental geometric principles.
This creates a highly polarized classroom environment. A professor cannot effectively deliver a fast-paced university calculus curriculum when one segment of the class is ready for multi-variable theorems and another segment is struggling with high-school level functions. The entire curriculum is forced to adjust downward. The result is a watered-down education that shortchanges well-prepared students while failing to save the underprepared from academic distress.
The Counterproductive Equity Argument
The original political consensus for removing the SAT focused entirely on equity. Activists and civil rights groups argued that standardized testing acted as a barrier for low-income, Black, and Hispanic students who could not afford expensive test-preparation courses. They claimed that eliminating the test would level the playing field.
The faculty letter argues the exact opposite.
"Failing to measure preparation gaps does not remove barriers; it moves them into the classroom, where they become harder to overcome."
When a university admits a student to a rigorous engineering or physics program without verifying their mathematical baseline, it is not an act of benevolence. If that student lacks the core skills to survive first-year calculus, they face two likely outcomes. They will either fail out of the major entirely, or they will spend thousands of dollars on remedial coursework, delaying their graduation and increasing their debt.
An objective test score allows the university to identify students from underfunded schools who managed to score exceptionally well despite having fewer resources. Without that objective data point, admissions offices lean even more heavily on factors that favor wealthy applicants. These include extensive extracurricular portfolios, niche sports, and participation in unpaid summer research programs.
Elite private institutions recognized this trend ahead of the public sector. MIT reinstated its standardized testing requirement after analyzing internal data that showed a lack of test scores left them unable to predict whether an applicant could handle their mandatory first-year math and physics core. Dartmouth, Yale, Brown, and Princeton followed suit after finding that test scores remained the single most reliable predictor of undergraduate academic success.
The High Cost of Remediation
The financial and institutional impact of this policy falls heavily on the public university system. Public universities are structured to graduate students in four years, moving cohorts through clear, sequential course maps.
Consider a standard engineering track. If a freshman cannot enter Calculus I during their first semester, their entire academic timeline shifts. They cannot take calculus-based physics. They cannot enroll in upper-division engineering labs. A single math deficiency can instantly transform a four-year degree into a five- or six-year financial commitment.
| Metric | Pre-2020 Policy Era | Post-2020 Test-Blind Era |
|---|---|---|
| UCSD Sub-High School Math Readiness | Baseline | 30x Increase |
| UC Berkeley Calculus Deficit Rate | Minimal | 20% to 30% of enrolled students |
| Primary Admissions Metric | GPA + SAT/ACT Balance | GPA + AI/Consultant Assisted Essays |
| Instructional Reality | Standard University Curriculum | Reteaching Middle School Math Concepts |
This delay creates an enrollment bottleneck. When upperclassmen are forced to repeat foundational courses, they occupy seats that should belong to the incoming freshman class. The university is forced to expand remedial infrastructure, hire additional lecturers, and fund tutoring centers to fix gaps that should have been addressed in high school.
The alternative is worse. Some campuses face intense pressure to alter grading scales and lower passing standards to maintain acceptable graduation rates. This directly devalues the worth of a University of California STEM degree in the eyes of employers and graduate schools.
A Hybrid Way Forward
The solution proposed by the faculty does not require a return to the rigid, system-wide testing mandates of the 1990s. Instead, it calls for a targeted, data-driven approach that respects the specific demands of technical majors.
A viable path forward involves a hybrid admissions model. The university could allow California residents to submit state-administered Smarter Balanced assessment scores from the 11th grade to prove baseline competency, while allowing out-of-state and international students to submit traditional SAT or ACT math scores.
Furthermore, individual departments require greater autonomy. The humanities and arts divisions may decide that standardized testing adds little value to their holistic evaluation process. That is their prerogative. However, the mathematics, engineering, and physical sciences divisions must have the authority to demand objective verification of numerical literacy.
Testing is an imperfect diagnostic tool. It can be coached, and it reflects socioeconomic disparities. Yet, as the University of California’s five-year experiment proves, abandoning the metric entirely creates a system that is far less fair, far less efficient, and damaging to the very students it aimed to protect.
The Board of Regents must decide whether it wants to maintain an ideological stance or preserve the academic integrity of its institutions. The current trajectory is unsustainable. A university cannot function as an elite research institution while simultaneously operating as a high-priced remedial high school.
