The largest four-year university system in the United States has removed SAT and ACT scores from its application requirements, marking a significant shift in the national discussion to eliminate standardized testing from admissions decisions.

Removing the requirement will “level the playing field” for all students, acting Chancellor Steve Relyea argued after the California State University’s Board of Trustees unanimously voted Wednesday to scrap standardized testing. The move will diversify the school system’s student body by removing obstacles that often hinder some prospective students from applying, the board said.
