About CSULB ProfCheck

CSULB ProfCheck adds Rate My Professor ratings directly into MyCSULB's class search results, so you can check a professor before you register without opening a new tab. How it works: - A small rating badge appears next to every instructor's name in your class search results - Click the badge to open a card with their overall rating, difficulty score, percent of students who'd take them again, department, and total review count - No RMP entry for that instructor? The badge just shows that clearly instead of leaving you guessing No account, sign-up, or setup required. Install it, search for classes like normal, and the ratings are just there. CSULB ProfCheck only reads the instructor names on the MyCSULB page you're already viewing. It doesn't track your browsing, collect personal data, or require any permissions beyond that. Built by a CSULB student, for CSULB students. Not affiliated with or endorsed by California State University, Long Beach, Oracle/PeopleSoft, or Rate My Professors. The professor name shown on the page you're viewing is sent to Rate My Professors' public API to retrieve their rating version 1.2.0: - new ProfCheck settings popup - hide classes with unrated professors - filter classes by any minimum professor rating - your filter settings now stay saved - general improvements to how ProfCheck handles class sections version 1.1.0: - added professor names as hyperlinks to their RateMyProfessors pages - added caching to make professor ratings load faster and reduce unnecessary requests version 1.0.0: - initial launch
