Requiring students to complete calculus before enrolling in STEM majors can create barriers for some learners to participate.

Math courses are often a barrier for students seeking to pursue a college credential, and for some, a lack of math curriculum during high school can make a STEM career seem out of reach.
A new course at Wentworth Institute of Technology in Boston serves as a stepping-stone for students who may not have had access to precalculus or calculus courses but are still interested in calculus-based learning. The university hopes the program will boost student enrollment and eliminate barriers to access for disadvantaged students.
What’s the need: The conversation about offering precalculus at Wentworth began in 2019, after university leaders saw that some students, despite having the same GPAs and high school transcripts as their peers, were less mathematically prepared, said Deirdre Donovan, Wentworth’s director of first-year math and interim associate dean of the School of Computing and Data Science.
At that time, Wentworth did not offer a math placement course, so all enrolled students launched at the calculus level.
Only four in 10 high school graduates have completed precalculus coursework, according to 2022 data. That number has grown from 36 percent in 2009, but the statistic reveals gaps in availability of the coursework for some high school students.
Wentworth, like many colleges and universities, requires students to have already completed calculus coursework to enroll in specific major programs, which is “a barrier that can prevent otherwise qualified students from pursuing engineering and computing degrees,” Donovan said.
To complete calculus by the end of high school, students had to complete Algebra I in eighth grade, and not every student was ready, aware of or offered that course at their school, Donovan said.
Some high schools also push students to complete AP Statistics in lieu of calculus, and Donovan said this shift “can actually close more doors at STEM schools than it might open, because those AP credits can’t replace the calculus-based statistics required for engineering degrees.”
Campus leaders at Wentworth opted to review policies that were barring students from participating in STEM programs, starting with creating a math placement process and then developing a precalculus course.
How it works: In 2024, Wentworth removed precalculus as an admissions requirement for students, paving the way for the college to admit about 10 percent more students who might have previously received a conditional acceptance, Donovan said.
New students without calculus credit are now enrolled in a four-credit, first-semester course called Foundations of Calculus that helps them get up to speed. The investment in additional content hours is an indication of the university’s commitment to opportunities for students who may not have been able to enroll and succeed previously, Donovan said.
In addition to two hours of lectures each week, students also participate in two hours of labs that focus on engineering problem-solving skills, using real-world problems that are tied directly to a student’s major.
The course is also supported by embedded peer tutors who can address student questions, clarify confusing content and facilitate study groups outside of class time.
It was important to Donovan and her faculty team not to work from a deficit-minded perspective about students’ knowledge gaps. Language regarding the course and its content hours was specifically crafted to help students feel like they’re being guided onto an on-ramp, not held back or punished for not having precalculus experience.
The results: After the first semester, staff have seen promising results, Donovan said. “We are pinching ourselves that it went exactly how we had hoped it would go.”
In fall 2024, about 200 students participated in precalculus either because they lacked the course in high school or their placement exam results indicated it would benefit them.
Approximately 75 percent of precalc students passed their course in the first term, on par with national averages. When they attempted calculus in their second semester, students had similar passing rates to their peers who completed calculus in the first term.
University faculty and staff were encouraged to see that engineering programs received 20 percent more applications this year, signaling an increased level of interest in rigorous programs, Donovan said.
Fall-to-spring retention rates were slightly lower for precalc students, but that could be due to other factors, including students re-evaluating their chosen major or deciding whether they want to be at a STEM-focused institution.
The course has also expanded enrollment opportunities for students who otherwise might not have considered Wentworth. Overall applications were up 25 percent year over year this past application cycle, and deposits were up 30 percent, Donovan said.
What’s next: Student feedback from the first term has indicated a need for an additional credit hour of in-person, interactive lab work, which will be implemented this fall. The hour, which the university is calling a companion class, will function similarly to a first-year seminar, teaching students study skills and metacognition, as well as connecting back math concepts.
None of the downstream courses such as physics have undergone a curriculum change, requiring students to get up to speed in their first term to be successful over all in college. Students who complete precalc also may need to take summer classes to ensure they graduate in four years, but the university is looking to offer affordable online courses to accommodate learners, Donovan said.
