This document provides guidance for developing quality student performance measures. It introduces a rubric to help teachers self-assess measures they create. The rubric examines measures across three strands: design, build, and review. It outlines steps to rate measures in each strand and provides examples of quality indicators like clearly stating the measure's purpose, aligning items to standards, and establishing cut scores for performance levels. The goal is to help teachers build rigorous, valid and reliable measures of student achievement.
