The second school Alpha opened, in Brownsville, Texas, faced serious questions from some of the parents who sent their children there in its first years after opening in 2022. More broadly today, though, experts say there is little outside scrutiny of Alpha’s model and how successful it really is at teaching children. Lee, the Stanford education expert, says the Alpha model represents a desire for schools to try different approaches. A spokesperson for the school said Alpha’s personalized learning model is designed to fix learning gaps developed in traditional schools. “No credible person who studies Alpha’s model first hand would say that foundational concepts are lost at Alpha,” she said.
