This week on “The Learning Curve,” Cara and Gerard are joined by Kate Walsh, president of the National Council on Teacher Quality. They discuss the qualifications of those who enter the teaching profession, explore teacher preparation, and key differences between teacher preparation, accreditation, and job prospects in the U.S. and other countries. They also speculate about what a Biden presidency might mean for K-12 education policymaking, and discuss how to diversify the teaching pipeline.
