UCLA began as the Los Angeles State Normal School, as did San José State, Eastern Michigan, and dozens of others. Each climbed the same ladder from normal school to teachers college to state college to comprehensive university, and most stopped caring about training teachers on the way up. The incentives were rational at every step, but model schools and single-purpose identity were casualties.
Herbst reads the climb as abandonment, Christine Ogren sees engines of opportunity, and Labaree calls it a tragedy for professional education but a triumph for access. Whether university-based preparation made worse teachers is inference rather than measurement.
