Teachers are a major factor in a student's academic performance. At ETS, our goal is to provide research-based learning tools and assessments that can be used to advance quality and equity in learning and teaching.
ETS’s research related to teaching quality is devoted to:
- improving the conceptual frameworks and proficiency models that undergird assessments of teaching
- designing, developing and studying assessments of teaching quality
- advancing scientific knowledge about the nature of teaching quality and how to measure it, concentrating on questions of validity and reliability
- better understanding the measurement models behind assessments of teaching quality
