Instructional Practice is one of three components in the Teacher Appraisal and Development System (TADS) and is weighted at 50% of a teacher’s Summative Rating. The Instructional Practice Rubric is comprised of three planning criteria and ten instructional criteria that are observable components of teachers’ practices in the classroom. The rubric is used to provide teachers with ratings following observations and walkthroughs conducted by their appraiser. Ratings for individual criteria range from four (highly effective) to one (ineffective) with performance characteristics outlined for levels of effectiveness. It is a district-wide expectation for teachers to achieve a rating of level three (effective).
