Using Content Knowledge for Teaching (CKT) to Gain Deeper Knowledge of Specialized Skills

Together with colleagues from the University of Michigan, ETS research scientists and assessment experts have worked to develop, research and refine assessments focused on the knowledge that teachers need to effectively engage in critical tasks of teaching: Content Knowledge for Teaching (CKT). Built on 25 years of research, CKT is emerging as a powerful tool for measuring the content knowledge used in teaching.
