One more thing to know

37 in 100 students (536 of 1,450) missed 10% or more of school days in 2025–26. That is about one and a third times the rate at the average Mt.

Each bar is Mt. Diablo High’s place among 1,498 California public high schools we score. Our calculation from California Department of Education records, updated October 15, 2026.

How to read these bars, and their sources

A place counts the schools out of 100 with a lower figure. The dashed line is the middle. Test results are from spring 2025, grade 11, the latest year with a high school Scope Score. That year the state called these levels Met or exceeded and Exceeded. Attendance counts students who missed 10% or more of school days; fewer is better, so a higher place means fewer such students.

What you can do

Who can act on Mt. Diablo High’s results?

The state has Mt. Diablo High in targeted support; Mt. Diablo Unified’s board decides its plan.

How to take part

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

What has the state flagged?

The state named it because results were low for homeless students. This support comes with a school improvement plan, which must use approaches with evidence behind them. Ask the principal to see the school improvement plan.

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.

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 113 of 319 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.

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.

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 $515,848,955 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.
