UC Berkeley faculty are raising a serious red flag about who walks into college math ready to do the work. The fight now is whether the university can even see that gap before students enroll.

Office Hours That Should Be About College Math

Three days a week, UC Berkeley teaching professor Zvezdelina Stankova walks into large math lecture halls that can hold hundreds of students. By the second week, she has written, she can already see who is in trouble. Some students, she says, are five to eight years behind. Office hours that should be spent on college-level material become lessons on fractions and basic algebra.

That is not a social-media paraphrase. It is how Stankova described her classroom in a San Francisco Standard op-ed, and how she put the same problem to Berkeleyside earlier in the summer: instructors are not arguing about advanced topics when a large enough share of the room needs a stop to re-explain adding fractions.

“There is a big chunk of students who are very well prepared, an equally big or larger chunk who have severe math deficiencies and almost no one in the middle,” Stankova told Berkeleyside. The result, faculty say, is two classes sharing one lecture hall: students ready for college math, and students still missing the middle-school floor underneath it.

What the Diagnostics Actually Show

The viral claim that “nearly a third” of students in Berkeley’s gateway math sequences cannot do middle-school-level work tracks faculty diagnostic reporting, not a random poll. Much of that evidence comes from readiness checks tied to first-semester Calculus I, which faculty treat as a clear window into wider math preparation.

In a UC Berkeley Letters & Science feature published June 11, 2026, Stankova pointed to CSU/UC Mathematical Diagnostic Testing Project results appended to the STEM open letter. Of the students entering Calculus I in fall 2023 who took the diagnostic and passed zero to two of eight topics, that group was 31 percent. Among those students, 46 percent later withdrew or earned a D or F in the course.

Stankova’s Standard op-ed, covered the same week by the New York Post, filled in the timeline. Before 2020, she wrote, about 71 percent of roughly 2,200 Calculus I students tested as ready or nearly ready, and only 0.14 percent tested below basic algebra. Among about 2,800 students tested from 2021 to 2023 on an eight-topic diagnostic, ready-or-nearly-ready fell to 51 percent overall and to 44 percent by 2023. Seventeen percent answered none of the eight topics correctly. By 2022-23, she wrote, more than one-third had severe math deficits, and zero was the most common score.

The UC STEM faculty open letter (PDF dated June 5, 2026) put the same crisis in system language: instructors “must reteach middle-school mathematics” while teaching college material, and “for three consecutive years, 20-30% of UC Berkeley first-semester calculus students who participated in mathematical diagnostic testing displayed severe preparation deficits.” Separately, that letter cites UC San Diego’s Senate-Administration Workgroup finding that roughly one in twelve entering students there tested below middle-school math. That is a San Diego cohort figure. It is not Berkeley’s percentage, and the article should not blur the two.

Why Faculty Want the Tests Back

Stankova and Svetlana Jitomirskaya were among five Berkeley faculty who helped launch a STEM open letter urging the University of California to restore SAT or ACT mathematics scores for STEM applicants, with faculty oversight of readiness standards. Berkeley L&S reported more than 1,450 signatures by June 11. By mid-July, Berkeleyside and the Los Angeles Times put the combined STEM and humanities letters around 3,000 faculty across the system. Stankova has said more than two-thirds of UC mathematics faculty signed.

Their argument is not that admitted students lack talent. It is that GPA-and-essay admissions, in an era of grade inflation and AI-assisted applications, no longer give campuses a reliable common signal of quantitative readiness. Without that signal, faculty say, students get a ticket into a dream major and then fail the first real filter. “If a student gets a ticket to a wonderful education at a UC campus only to fail their first class, that derails them,” Stankova told Berkeley L&S. “That is a financial burden on the state, on the parents, and on the student.”

Math chair Martin Olsson, who signed the letter, put the human cost in one line: growth is the goal until it becomes survival. Department interventions already exist. Alexander Paulin’s summer and fall “Foundations of Lower Division Mathematics” pathway grew out of a 2020 online pre-calculus pilot. Faculty still say remediation after arrival is not the same as matching students before they enroll.

The Case Against Treating the SAT as the Fix

Critics do not deny that preparation gaps are real. They dispute the cause and the cure.

Jesse Rothstein, director of UC Berkeley’s Center for Studies in Higher Education, told Berkeleyside the pandemic left students more on their own, and that inequality in home resources widened the split. Eddie Comeaux, a UC Riverside education professor who co-chaired the 2020 faculty testing study, argued the university should study which campus supports help students thrive despite gaps, rather than reaching first for the SAT. UC Santa Barbara math chair Bjorn Birnir, who did not sign the letter, described a placement-test and community-college catch-up path he says works without restoring admissions testing.

The UC Student Association opposed bringing the tests back, warning that racial and social disparities in admissions would reappear. Berkeley L&S also summarized research by Saul Geiser arguing high school GPA can be a stronger first-year predictor than standardized tests, and that test-centered systems can disadvantage high-GPA students from less privileged schools. Selective peers such as MIT, Stanford, Harvard, and Yale have restored testing. FairTest still counts more than 2,000 colleges as test-optional or test-free. Both facts can sit in the same paragraph.

What This Means in K-12 Classrooms

College diagnostics are a late alarm. The skills Stankova lists — fractions with unlike denominators, basic algebra fluency, the quiet number sense underneath college math — are middle-school and early-high-school work. When a selective public university says those gaps are walking into gateway math courses, the story is also about what transcripts, course titles, and gradebooks signaled for years before the acceptance letter.

Olsson told Berkeley L&S he does not blame individual teachers. “My experience with K-12 teachers is that they’re absolute heroes,” he said. That line matters for readers who live in middle-school math departments, not faculty senate meetings. The pressure showing up in Berkeley lecture halls is the same pressure teachers already feel when grade inflation, accelerated course labels, pandemic unfinished learning, and short attention spans collide in one classroom.

National context does not let anyone pretend this is only a Berkeley admissions quarrel. Berkeley L&S cited NAEP “Nation’s Report Card” findings that 45 percent of 12th graders scored below basic in math on the latest assessment discussed in that piece, with the gap between the top and bottom wider than ever. For a seventh-grade teacher drilling fraction operations, or an Algebra I teacher fighting to keep fluency from collapsing, the college story is a mirror: students can collect impressive GPAs and still arrive years off the course they were told they were ready for.

What Happens Next

UC’s Academic Senate has opened a review of standardized testing in admissions. Berkeleyside reported that board chair Maria Anguiano expects a faculty recommendation by June 2027. Stankova has warned that a slow calendar can push any new policy toward fall 2028 admits. Berkeleyside also noted the original hard floor of fall 2028 was later withdrawn, leaving current high school juniors unsure what to prepare for. Peer campuses have not waited. UC, for now, is still studying.

Stankova keeps insisting the letter is not a culture-war prop. “This is not a political matter,” she told Berkeley L&S. “It is an educational matter.” The educational matter, for OMC’s classroom audience, is blunt: if gateway math at Berkeley is absorbing middle-school reteaching at scale, the years that build fraction fluency and algebra automaticity were already the make-or-break stretch.

Frequently Asked Questions

Is it true that nearly a third of UC Berkeley math students can’t do middle-school math?

Faculty reporting supports a “nearly a third” paraphrase with labels. Berkeley L&S cited 31 percent of fall 2023 Calculus I diagnostic takers passing only zero to two of eight MDTP topics — a gateway-math readiness check faculty use as evidence of a wider preparation split. Stankova wrote that by 2022-23 more than one-third of tested Calculus I students had severe math deficits, with zero the most common score. The STEM open letter separately cited a 20-30 percent severe-deficit band across three years for Berkeley diagnostic participants. Those are diagnostic subgroups, not a claim that every student in every section lacks middle-school skills.

Who raised the alarm, and what did they ask for?

UC Berkeley mathematicians including Zvezdelina Stankova and Svetlana Jitomirskaya helped lead a STEM faculty open letter calling for reinstatement of SAT/ACT mathematics requirements for STEM-major applicants, plus faculty oversight of readiness standards. Thousands of UC faculty across STEM and other fields signed related letters in spring and summer 2026. Math chair Martin Olsson signed; Alexander Paulin has been building on-campus foundations coursework for underprepared students.

Does everyone agree the SAT should come back?

No. Critics argue pandemic learning loss, family resources, and high school inequality explain much of the readiness split, and that restoring tests could rewiden access gaps. Alternatives on the table in reporting include stronger placement systems, community-college catch-up pathways, Smarter Balanced as a possible California signal, and heavier investment in campus supports. UC student leaders have opposed restoring the SAT and ACT. The regents will decide after the Academic Senate review.
