How SchoolScope works
Three steps to finding the right school.
Search your school
Find any California elementary school by name, city, or district.
See the full picture
Six dimensions analyzed: test scores, exceeded vs. met split, growth trajectory, absenteeism, and more.
Compare with confidence
Side-by-side comparisons with transparent methodology. No mystery algorithms.
Why parents switch to SchoolScope
The data other sites don't show you.
Beyond the single number
We split "proficient" into exceeded vs. met. A school where 40% exceed standard looks very different from one where 40% meet it.
Track real growth
Our growth trajectory shows whether scores improve from grade 3 to 5. Some schools coast on incoming talent. Others actually add value.
The full picture
Chronic absenteeism and suspension rates reveal school culture that test scores alone can't. We weigh all of it in one Scope Score.

How we score
Six dimensions, weighted by what actually predicts school quality. Full methodology
% Exceeded Standard
The ceiling. Measures whether a school pushes strong students past proficiency, not just to it.
% Met + Exceeded
The floor. Baseline proficiency — are most students clearing the bar?
Growth G3 to G5
Is the school adding value, or coasting on incoming talent? Measures improvement across grades.
Chronic Absenteeism
School culture and family engagement. Lower is better — kids who show up learn more.
Suspension Rate
Discipline philosophy matters. High suspension rates signal punitive culture over supportive.
Baseline Proficiency
Additional floor weight ensuring raw proficiency counts in the overall picture.

Frequently asked questions
What is SchoolScope?
SchoolScope is a school performance analysis tool that uses California's official public test data (CAASPP) to score schools across 6 dimensions: exceeded standard rate, met+exceeded rate, grade-to-grade growth trajectory, chronic absenteeism, suspension rate, and baseline proficiency. It surfaces what sites like GreatSchools and Niche don't show — the difference between schools that meet standard and schools that push kids past it.
How is SchoolScope different from GreatSchools?
SchoolScope separates "exceeded standard" from "met standard" — a distinction GreatSchools doesn't make. A school where 60% of students exceed standard is fundamentally different from one where only 10% exceed. SchoolScope also tracks grade-to-grade growth trajectories and includes chronic absenteeism and suspension rates in the Scope Score. The full methodology is published transparently.
What data does SchoolScope use?
All data comes from official public sources: CAASPP Smarter Balanced test scores, chronic absenteeism rates, suspension rates, graduation rates (ACGR), and College/Career Indicator data from the California Department of Education (CDE), plus enrollment and demographics from the NCES Common Core of Data. The 2024-25 school year is the current data year.
Is SchoolScope free?
Yes. Basic Scope Scores, state rankings, and school profiles are free for all California schools. SchoolScope analyzes over 8,500 schools across elementary, middle, and high school levels.
What is the Scope Score?
The Scope Score is a 0–100 rating that combines multiple performance signals into a single number. The Scope Score weighs exceeded standard rate (30%), met+exceeded rate (20%), growth trajectory (15%), chronic absenteeism (15%), suspension rate (10%), and baseline proficiency (10%). Each school level (elementary, middle, high) uses a different formula tuned to the data available at that level. See the full methodology.
