NCTE is conducting multiple studies regarding teacher effectiveness.

Core Study
Developing Measures of Effective Mathematics Teaching is the core study of NCTE. The objective of this study is to identify practices and characteristics that distinguish between more and less effective mathematics teachers. This information will be used to develop a suite of empirically validated and practical instruments that can be used by school districts to identify, recruit, develop, and retain more effective teachers.

Supplemental Studies
The secondary aim of NCTE is  to formulate and carry out the results of supplementary research studies that are responsive to the needs of education practitioners and policymakers. Topics include:

• determining why teacher effects fade out,
• examining whether participation in teacher evaluation systems improves teacher effectiveness,
• assessing the robustness of classroom observation scores under different scoring conditions, and
• exploring whether professional environments in schools promote teacher development.

Resources
NCTE has hosted both a national conference and webinar series, convening researchers, policymakers, and district and school leaders to present the latest research on measuring teacher effectiveness and effective teaching practices. NCTE also addresses current issues and provides additional information in the hot topics section of this website. Further, since measuring teacher effectiveness is now an important part of national education policy, NCTE plans to work with states and large districts as they embark on developing critical teacher evaluation systems.
