“Given that too many schools don’t teach calculus, chemistry and physics, CalTech is allowing potential undergraduates to demonstrate their ability in these fields by using Khan Academy,” writes Slashdot reader Bruce66423. Los Angeles Times reports: 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.

The impetus for the policy change began in February, when Pallie, the admissions director, and two Caltech colleagues attended a workshop on equity hosted by the National Assn. for College Admission Counseling. They were particularly struck by one speaker, Melodie Baker of Just Equations, a nonprofit that seeks to widen math opportunities. As Baker pointed out the lack of access to calculus for many students, Pallie and her team began to question Caltech’s admission requirement for the course, along with physics and chemistry. Pallie and Jared Leadbetter, a professor of environmental microbiology who heads the faculty admissions committee, began to look into potential course alternatives. Pallie connected with Khan’s team, which started a second nonprofit, Schoolhouse.world, during the pandemic in 2020 to offer free tutoring. Peer tutors on the platform certify they are qualified for their jobs by scoring at least 90% on the course exam and videotaping themselves explaining how they solved each problem on it. The video helps ensure that the students actually took the exam themselves and understand the material. That video feature gave Caltech assurances about the integrity of the alternative path.
Under the new process, students would take a calculus, physics or chemistry class offered by Khan Academy and use the Schoolhouse platform to certify their mastery of the content as tutors do with a 90% score or better on the exam and a videotaped explanation of their reasoning. Proof of certification is required within one week of the application deadline, which is in November for early action and January for regular decisions. Pallie and Leadbetter also wanted to test whether the Khan Academy courses are sufficiently rigorous. Several Caltech undergraduates took the courses to assess whether all concepts were covered in enough breadth and depth to pass the campus placement exams in those subjects. Miranda, a rising Caltech junior studying mechanical engineering, took the calculus course and gave it a thumbs-up, although she added that students would probably want to use additional textbooks and other study materials to deepen their preparation for Caltech.
