Strengthening Foundations: University of Pennsylvania Tightens Prerequisites for Advanced Mathematics

Jakarta – In a significant shift aimed at bolstering academic excellence and ensuring student success, the University of Pennsylvania (Penn)—consistently ranked among the top 15 institutions globally according to the Times Higher Education World University Rankings 2026—has initiated a rigorous enforcement of prerequisites for its advanced mathematics curriculum. This policy, effective as of the current semester, marks a departure from the university’s previous reliance on student self-assessment, signaling a broader movement in higher education to address concerns regarding mathematical proficiency.

The Shift: From Self-Selection to Verification

For years, the prerequisites for courses such as Calculus, Linear Algebra, and Differential Equations were clearly outlined in Penn’s academic catalog. However, the university historically operated on an honor system, trusting students to evaluate their own academic readiness before enrolling in complex, high-level courses.

This semester, the College of Arts & Sciences, in collaboration with the Department of Mathematics, has moved to a proactive verification model. During the registration process, the university now systematically checks whether students have satisfied the necessary prerequisites before allowing them to finalize their enrollment.

Molly McGlone, Associate Dean for Undergraduate Studies at the College of Arts & Sciences, emphasized that this move is fundamentally about educational alignment. "This semester, the College and the Mathematics Department are working together to implement a process to verify that students meet the existing prerequisites at the time of course registration," McGlone stated in an interview with Inside Higher Ed.

She added that the policy is designed to place students in learning environments that match their current readiness levels. "This change reflects careful consideration regarding how to support students in learning at the appropriate level, which we believe will enhance learning outcomes for all," she said.

A Response to Academic Misalignment

The decision to formalize verification was not made in a vacuum. Jonathan Block, Chair of the Department of Mathematics at Penn, shed light on the internal struggles that necessitated this policy change. In comments made to The Daily Pennsylvanian, Block highlighted the issue of "over-enrollment" in classes where students lacked the foundational knowledge to succeed.

"We are striving to provide better guidance and placement within the curriculum," Block explained. "In several instances, students have bypassed prerequisites and registered for classes they believed they were prepared for, only to find the material overwhelmingly difficult."

By enforcing these barriers, the department aims to mitigate the frustration and academic strain experienced by students who find themselves in advanced courses without the necessary mathematical scaffolding. This structural change is intended to ensure that the time spent in the classroom is productive rather than remedial.

The Broader Landscape: Mathematical Literacy in Crisis

The policy shift at Penn arrives at a moment of profound national anxiety regarding mathematics education in the United States. While Penn’s move is specific to its curriculum, it reflects a nationwide debate about how colleges should handle the transition from high school mathematics to university-level STEM requirements.

Pamela Burdman, founder and executive director of Just Equations—a California-based nonprofit focused on mathematical equity—notes that while prerequisites are a standard feature of higher education, the strategy of implementation is evolving.

"The form and intensity of these requirements change over time," Burdman noted. Many university systems are currently grappling with the legacy of remedial courses, which were once the standard for students deemed "under-prepared." In recent years, institutions have moved toward "corequisite" models—where students take college-level courses while simultaneously receiving supplemental support. Research has shown that many students were previously relegated to lower-level classes unnecessarily, despite possessing the capacity to succeed in more rigorous environments.

Data and Disparities: The "Calculus Gap"

The challenges inherent in university mathematics are often rooted in the lack of consistency in high school preparation. Citing research by David Bressoud, Professor Emeritus at Macalester College and former president of the Mathematical Association of America, Burdman highlighted a sobering statistic: only about one in five students who take calculus in high school proceed to take Calculus II in college.

This "leak" in the academic pipeline suggests that a majority of students who have already been exposed to calculus either choose to retake introductory material, opt for lower-level mathematics, or move into non-STEM pathways that do not require calculus, such as business mathematics.

Furthermore, access to advanced coursework at the secondary level remains deeply unequal. "Access to calculus at the high school level is not uniform," Burdman explained. She pointed to long-standing disparities where Black and Latinx students, on average, have significantly less access to advanced math curricula in their schools. Consequently, many universities are now forced to offer "precalculus" as a necessary bridge for students who were deprived of the opportunity to take it earlier in their academic journeys.

The Pandemic and the "Skills Slide"

The urgency surrounding this issue is compounded by a documented decline in mathematical proficiency. A report published in November 2025 by the University of California, San Diego, revealed a staggering statistic: the number of first-year students testing below middle-school proficiency in mathematics has increased nearly 30-fold over the last five years.

This alarming trend has prompted hundreds of mathematics professors within the University of California system to advocate for the reinstatement of standardized testing, such as the SAT and ACT, for admissions. The rationale is that these tests provide a baseline metric of academic readiness that has become increasingly difficult to gauge in a post-pandemic landscape.

Burdman suggests that while the COVID-19 pandemic acted as an accelerant for this decline, the downward trajectory in math scores began well before 2020. She cites a complex web of long-term factors contributing to the trend:

• Chronic Absenteeism: The disruption of consistent, in-person instruction has left gaps in fundamental learning.
• Digital Distraction: The ubiquitous nature of social media and the subsequent decline in deep-focus work.
• Generative AI: The reliance on AI tools for homework and problem-solving, which, if used improperly, can bypass the critical thinking processes required to master mathematical concepts.

Implications for Future Students

For students at institutions like the University of Pennsylvania, these policies represent a move toward "high-touch, high-rigor" education. By tightening the reins on prerequisites, Penn is effectively saying that excellence cannot be rushed.

However, this approach carries a dual responsibility. While the university is ensuring that students are ready for the complexity of advanced courses, the broader educational system must address the underlying inequities in high school math preparation. If elite universities only admit students who have had access to premium prep, the gap in STEM representation may widen.

The challenge for the coming years, therefore, lies in balancing the enforcement of high standards with the provision of accessible pathways for students to reach those standards. Whether through enhanced summer bridge programs, better advising, or more robust corequisite support, the goal remains the same: ensuring that the next generation of mathematicians, engineers, and scientists are built on a foundation that is not just broad, but deep.

As Penn continues to refine its verification processes, the academic community will be watching closely. The university’s attempt to restore the integrity of its curriculum may well serve as a template for other top-tier institutions struggling to balance the competing pressures of academic rigor and the evolving landscape of student preparedness in the 21st century.
