Teaching Effectiveness Scale
Also known as: TES, Instructor Effectiveness Rating
The Teaching Effectiveness Scale (TES) is a validated instrument designed to measure students' perceptions of instructor effectiveness across multiple dimensions. The most widely known version, the Student Evaluation of Educational Quality (SEEQ), developed by Marsh (1982), assesses nine dimensions of teaching including learning value, enthusiasm, organization, group interaction, and course difficulty, providing comprehensive feedback on instructor performance.
Key highlights
- Multidimensional: captures diverse aspects of teaching that single-item ratings miss
- Empirically validated: SEEQ and similar instruments have strong reliability and construct validity
- Practical and quick to administer; feasible across institutional contexts
- Actionable feedback: specific dimension scores help instructors target improvement efforts

When to use it
The TES is used for instructor evaluation in higher education for annual reviews, tenure and promotion decisions, course improvement, professional development planning, and research on teaching quality. It is particularly valuable when combined with other evidence such as peer observation, student learning outcomes, and self-reflection.
Strengths & limitations
- Multidimensional: captures diverse aspects of teaching that single-item ratings miss
- Empirically validated: SEEQ and similar instruments have strong reliability and construct validity
- Practical and quick to administer; feasible across institutional contexts
- Actionable feedback: specific dimension scores help instructors target improvement efforts
- Potential response bias: students' ratings may reflect grade expectations, instructor likeability, or perceived workload rather than actual learning
- Correlation with course difficulty: inherently difficult courses may receive lower ratings despite effective instruction
- Ceiling effects in some contexts: courses with strong institutional support may show inflated ratings

Frequently asked
Do teaching effectiveness ratings predict student learning outcomes?
Research on this relationship is mixed. Moderate positive correlations exist between some dimensions (organization, clarity) and learning, but student satisfaction does not always align with measured achievement gains. Institutions should use effectiveness ratings alongside learning outcomes assessment for a complete picture.
How can an instructor improve a low dimension score?
First, review student comments to understand specific concerns. Then, seek support: observe a colleague's class, attend teaching workshops, consult educational resources on that dimension (e.g., group facilitation, course structure), and try targeted changes. Improvement typically requires sustained effort over one or more terms.
Should student evaluations influence tenure decisions?
Most institutions include them as one factor among several: peer observation, student learning outcomes, course materials, and instructor self-reflection. Using evaluations as the sole criterion risks bias; a balanced approach respects student voice while recognizing that excellence in teaching is multifaceted.
