The California School Campus Database records Chaparral High, Eagle Summit Community Day and Pinon Mesa Middle on this campus too; it gives each school the whole campus, so this drawing doesn’t show which buildings each uses.

Drawn from OpenStreetMap, inside the campus outline from the California School Campus Database (2025). Volunteers map it, so a new building may be missing. Buildings with no mapped height are drawn one storey high.

Schools maintain a closed campus policy. For students’ safety, visitors may enter a campus only with the school’s official permission; this drawing implies no permission to enter.

What you can do

Who can act on Serrano’s results?

The state took Serrano out of extra targeted support; Snowline Joint Unified’s board decides its plan.

What has the state flagged?

It came off the list for 2025–26; it was on it in 2024–25.

Federal designation under the Every Student Succeeds Act, 2025–26. Source

The state is giving Snowline Joint Unified extra help in 2026. It qualified on the 2025 California School Dashboard. The county office must help the district for at least three years, including a review of its yearly plan.

Extra help for Snowline Joint Unified: CDE’s assistance status file for the 2025 California School Dashboard. Source

When is the plan set, and how can you take part?

Snowline Joint Unified’s board must adopt its yearly plan (LCAP) by July 1, after at least one public hearing at an earlier meeting.

How to take part

Watch the board’s agenda: the hearing is posted at least 72 hours ahead.
Send written comments on the actions and spending the plan proposes.
Raise questions through the district’s parent advisory committee; the superintendent must answer its comments in writing.
Read the midyear report, due by February 28.

Where these figures come fromEach measure’s source, student group and definition

Graduated in four years: 2024–25 · 427 of 464 students who started 9th grade together. California Department of Education, adjusted cohort graduation records. Comparison is SchoolScope’s combination of graduates and cohort counts across the reference schools, not CDE’s published state rate.
Ready for college or career (state measure): 2024–25 · 243 of 464 students in the state’s measure. California Department of Education, College/Career Indicator (CCI), overall “Prepared” rate, among the students in the indicator’s group. Prepared is CDE’s overall classification, not AP participation or a college admission rate.
Finished the UC/CSU course list: 2024–25 · 127 of 427 graduates finished the UC/CSU course list. California Department of Education, A–G completion records (graduates who met the UC/CSU course requirements). Course completion is separate from college enrollment.
Where students who finished high school went: CDE college-going records, class of 2023. College enrollment is counted for 12 months after finishing high school and matched to college records, so this runs about two years behind. A dash is unavailable, not zero.

Links do not guarantee placement. Charter, magnet, transfer and other admission routes can differ. Each school’s percentile compares it with California schools at its own level (continuation and alternative schools only with their own kind); the stages are not one ranking. Older zone links come from the federal School Attendance Boundary Survey (NCES SABS).

Index is where the school's value sits among the California high schools we score, from 0 to 100, where 50 is their average; it is not a percentile. School values are from 2024–25. Chronic absence and suspension are CDE's all-students school rates; the score uses an adjusted version of each that pulls small schools toward the average, so their index can sit nearer 50 than the rate suggests.

A grade the school doesn't teach has no row. “Suppressed” marks a result CDE blanks because fewer than 11 students tested (CDE’s reporting rule); “none tested” marks a grade CDE lists with no students tested; “not on file” marks a result missing from the records we hold. None of them means zero.

AP pathway among CCI Prepared studentsCDE College/Career Indicator · CCI source year 2025 · all students · AP pathway rate 43% · AP-pathway numerator 105 · denominator 243 (CCI Prepared students). This measure uses Prepared students as its denominator, not the whole CCI cohort; it is not an AP exam-taking rate or a count of AP courses offered. That cohort includes all students in the current four-year graduation cohort plus only Prepared fifth-year graduates from the prior cohort. In 2025 the pathway accepts two qualifying AP exams, two qualifying AP courses, or a combination of one of each in different subjects.

CDE's overall Prepared rate is the college-readiness factor in the Scope Score (20% of the high school score). The school rate is 243 of 464 CCI students, not the AP-only pathway or A–G completion rate. The California figure is CDE's statewide CCI student cohort, not an average of SchoolScope's comparable high schools or the SchoolScope school-rank pool.

Source: UC admissions by source school. Dated fall first-year UC applicants, admitted students, and enrollees. GPA is each group's mean weighted, capped high-school GPA for 10th/11th-grade college-preparatory courses. SchoolScope leaves GPA unavailable when several CEEB codes contribute rather than combining their means. UC blanks counts under 5 applicants or under 3 admits or enrollees, shown here as “under 5” or “under 3”; — means unavailable, and a reported zero remains zero. A + marks a partial SchoolScope sum of observed counts, not a complete total; missing contributions may be zero. No admit rate is computed here. Complete, matching counts can support a historical descriptive rate, but do not establish a school's effect or predict individual chances. Series shown from 2016.

How the California mean was selected

SchoolScope starts with its selected California finance records, not every NCES California district. For FY 2020–21, it calculates an unweighted mean of NCES F-33 current expense per pupil. District records contribute once, regardless of enrollment. The calculation keeps records with positive per-pupil current expense, enrollment over 100, CCD agency type 1, and a recorded district name; it excludes names ending in County Office of Education, Department of Education, or Superintendent of Schools. This is a SchoolScope calculation, not a state-published spending average.

These shares are our arithmetic: each group’s dollars divided by the $139,160,777 total of the groups shown, rounded to whole percents by largest remainder so they add up to 100. Dollar amounts are rounded to the nearest dollar, so they can differ from the total by a dollar. SchoolScope groups district-level CDE SACS UserGL actuals from Fund 01, using operating objects 1000–5999 and excluding retiree benefits, food and community services, facilities acquisition, other outgo, and nonagency goals. These shares use that filtered total; they do not exactly break down CDE's official current expense per ADA above. The school-level ESSA figure uses a separate source.
