What does the Scope Score measure?
The Scope Score is SchoolScope's proprietary composite rating (0–100) based on six dimensions of publicly available California school data: the exceeded-vs-met standard split, overall proficiency, grade 3–5 growth, chronic absenteeism, suspension rate, and ELPAC English Learner proficiency. Unlike single-number ratings, the Scope Score separates students who "exceeded" from those who "met" the standard — revealing whether a school pushes students beyond proficiency or paces toward it.
