Classroom Observation Scales-Revised (COS-R) and Student Observation Scales (SOS)

The COS-R and the SOS are observation scales being used in all Project Athena classrooms. The scales are divided into six subscales:

Accommodating for Individual Differences
Creative Thinking Strategies
Critical Thinking Strategies
Curriculum Planning and Delivery
Problem Solving
Research Strategies

Each subscale has 3-5 corresponding items that target certain teacher behaviors exhibited during classroom instruction. Each behavior focuses on research-based best practices in the field of gifted education. The scales are meant to be used as growth tools and baseline data on which to base professional development decisions. They are not meant to be used as teacher evaluation tools.
