Student-centered grading shifts the focus from traditional points-based systems to practices that emphasize learning, revision, and growth. Students receive meaningful, ongoing feedback, track their own progress, and have multiple opportunities to demonstrate understanding. Alternative approaches, such as standards-based, specifications, and contract grading, are grounded in evidence-based practices that reduce student anxiety and strengthen retention and belonging in STEM. Through the Collaborative, educators across institutions explore and refine these methods together, scaling effective practices to create grading systems that enhance transparency, deeper learning, and persistence in STEM.
