Frequently asked questions

How many schools are listed in 91773?
This SchoolScope directory lists 10 public schools in 91773 (San Dimas) with 2024–25 reporting records. This is directory coverage, not a complete campus inventory. Each school appears under its primary reporting level; a K–8 or K–12 campus may serve additional grades.

High: San Dimas High (68/100). These are separate level rankings, not a single cross-level league table. A score does not establish fit or enrollment eligibility. See the methodology.
Can I compare elementary, middle, and high schools directly?
Compare schools at the same level and within the same enrollment group. Scope Score formulas and available measures differ by level. The plots show comprehensive public schools separately for each level; individual profiles explain their comparison group.
Are schools in 91773 assigned to every address in that ZIP code?
No. ZIP codes organize mail and school listings; they are not school attendance boundaries. Confirm your address, grade, program, and enrollment requirements directly with the school or district.
What does a SchoolScope pattern mean?
Archetypes summarize patterns in publicly reported academic and school-climate measures. They describe reported results, not a school’s quality or a child’s fit. Open the school profile for reporting years, missing measures, and questions to ask. Read how the patterns are defined.
Where do these results come from?
The underlying public data comes from the California Department of Education, including CAASPP reporting for 2024–25. Scope Scores and archetypes are SchoolScope calculations, not official CDE ratings. View CDE data and SchoolScope’s methodology and limitations.
