“Mya Alford dreams of studying chemical engineering in college, but the high school junior is at a disadvantage: Last year, her chemistry teacher at Pittsburgh’s Westinghouse Academy quit just weeks after school started, and the class was taught by a substitute who, as Alford put it, ‘didn’t know chemistry.’
The year before, there was no permanent biology teacher until December. Students at Westinghouse, a high-poverty school in one of Pittsburgh’s roughest neighborhoods, often see a rotating cast of substitutes, Alford said.”
