In a Reddit AMA, Silver expresses his concern about the practice.
Over the past few years one of the most controversial topics in education reform has been measuring teacher effectiveness with standardized tests. Well, on Tuesday, the Jon Stewart-dubbed "Lord and God of the Algorithm," Nate Silver, participated in a Reddit AMA and the top question tackled the issue head-on.
Indeed, user GrEvTh asked Silver, "What are your thoughts on data-driven metrics for teacher evaluation? Do you think a system that accurately reflects teacher value could ever be created, or will it always be plagued by perverse incentives (teaching to the test, neglecting certain types of students, etc)?"
