Yale Ends Exam Waiver for Intro CS, Tightens Prerequisites for Data Systems Course
Yale University has announced a major curriculum reform in computer science. Starting fall 2025, students aiming to enroll in the pivotal Data Systems and Programming Techniques (CPSC 2230) must first complete either Introduction to Computer Science (CPSC 2010) or Introduction to Information Systems (CPSC 2000). The waiver option, previously used by many advanced students, will no longer be available.
A lecturer for Data Systems and Programming Techniques explained that the withdrawal of the waiver exam reflects concerns about its effectiveness. “Previously, we administered a waiver exam, but we found this approach not as effective as we anticipated,” the lecturer told the Yale Daily News. While performance metrics were not disclosed, the policy shift signals that hands-on programming experience alone does not guarantee readiness for the theoretical and historical aspects embedded in computer science education.
