When using OPTIC, facilitators assign groups of educators to a calibration task focused on a specific grade-level, content area, or element of the rubric. To complete a calibration task, participants view a video of classroom instruction or other artifact of teaching and learning, score practice based on evidence, and draft written feedback to the teacher. Participants can then view real-time data displays of the scores and feedback provided by others in the group, as well as by role, school, district, or across the state. Groups can use this information to facilitate a discussion of evidence, perceptions of practice, and the characteristics of high-quality feedback.
