Teachers With High Licensing Scores Found More Effective.

The article cites a study conducted by researcher Dan D. Goldhaber which reveals that students whose teachers score high on state licensing exams learn more mathematics over the course of a school year than peers taught by teachers with low scores. The findings provide important evidence that teacher-licensing exams may be meeting their purpose in screening out ineffective teachers. Some experts argue for raising the bars that would-be teachers have to cross to enter the field, while others argue for creating alternative routes into the profession to make it easier for talented professionals from other fields to enter the classroom.
