Kimberly Miranda is the brainy daughter of Guatemalan immigrants and the first in her family to attend college. But she almost didn’t make it to the California Institute of Technology.
Her Redwood City school didn’t offer algebra in eighth grade, which threw her off the progression of high school math classes leading to calculus — a long-standing Caltech admission requirement. Miranda managed to double up on math courses in sophomore year to reach calculus as a senior, but not all students have the wherewithal — or support — to take that path.
And scores of students don’t even have that chance, because more than one-third of the nation’s high schools don’t offer calculus, and many also lack physics and chemistry classes, two other Caltech admission requirements. For years, the institute, a global powerhouse of science, technology, engineering and math education, fielded hundreds of calls each year from distraught students and parents about the issue. But Caltech held firm, making no exceptions, even for “absolutely astounding” applicants, as one faculty member put it.
Now Caltech, in the name of equity, is shifting gears. In a groundbreaking step, the campus announced Thursday that it will drop admission requirements for calculus, physics and chemistry courses for students who don’t have access to them and offer alternative paths to prove mastery of the material.
“Brilliant students exist in every single part of this world and in every single community, and this idea that families have to choose the future of their kids and where they’re going to go for college based on their ZIP Code seemed so unfair,” said Ashley Pallie, Caltech’s executive director of undergraduate admissions. “We need to continue opening this door of opportunity.”

One of Caltech’s alternative paths is taking Khan Academy‘s free, online classes and scoring 90% or higher on a certification test. Sal Khan, academy founder, said Caltech’s action is a “huge deal” for equitable access to college. While Caltech is small — only 2,400 students, about 40% of them undergraduates — Khan said he hoped its prestigious reputation would encourage other institutions to examine their admission barriers and find creative solutions to ease them.
The Pasadena-based institute, with a 3% admission rate last year, boasts 46 Nobel laureates and cutting-edge research in such fields as earthquake engineering, behavioral genetics, geochemistry, quantum information and aerospace.
“You have one of the most academically rigorous schools on the planet that has arguably one of the highest bars for admission, saying that an alternative pathway that is free and accessible to anyone is now a means to meeting their requirements,” said Khan, whose nonprofit offers free courses, test prep and tutoring to more than 152 million users.
Even as demand for STEM skills accelerates, federal data for 2017-18 showed that only 65% of public high schools offered calculus that school year.
