Mountain Oaks

• In 2022-23, 90% or more of the 47 students in its four-year cohort graduated with a regular diploma within four years: ED publishes a range, not a figure, to protect students’ privacy.
• In 2021-22, between 90% and 94% of the 70 students in its four-year cohort graduated with a regular diploma within four years: ED publishes a range, not a figure, to protect students’ privacy.

• A public charter school for grades K to 12.
• Open in NCES’s 2025-26 directory, which is still preliminary.
• In 2024-25, 52% of students were eligible for free or reduced-price lunch, 223 of the 425 enrolled on October 1: 190 for free lunch and 33 for reduced-price.
• NCES counts 178 students directly certified for free meals in 2024-25, without an application, through their families’ part in programs such as SNAP.
• Around the school, a family with children aged 5 to 17 has an income of about 207% of the federal poverty threshold for its size (100% is at the threshold), by NCES’s 2021-22 estimate from the Census Bureau’s American Community Survey of 2018-2022; its standard error is 80 points.
• That describes the school’s neighbourhood, which NCES says may differ from the neighbourhoods its students live in.

What the school reported to the Office for Civil Rights for 2023-24. These are the school’s own counts, not findings.

• Among the 12 nearest public schools in California, within 36.2 miles, the middle value for chronic absence in 2022-23 was 2.9%; this one had 7.2%.

• Run by Calaveras County Office of Education, its local education agency in NCES’s directory.
• Its charter authorizer, as NCES lists it: CALAVERAS COUNTY OFFICE OF EDUCATION.
• District spending, fiscal year 2024: Calaveras County Office of Education spent $44,425 per student, by the Census Bureau’s count of the district’s spending and its 438 students, of which $20,023 went on instruction and $24,233 on support services such as administration, buildings and transport.
• That is the district’s figure across all its schools, not this school’s own: its day-to-day spending on salaries, benefits, services and supplies, not on construction, equipment, debt or payments to other school systems.

• Federal school data don’t record findings against a school: the counts here are what the school reported, and the Office for Civil Rights’ own investigations aren’t included.

• Federal school data arrive one to three years after the school year they describe, so each figure here carries its own year.
• To protect students’ privacy, ED adds or takes away one at random from chronic absence counts of four or fewer, so a small count may be one off.
• ED publishes each school’s test results in reading and language arts and in mathematics, but they aren’t loaded here yet.
• ED publishes most schools’ results as ranges, wider for smaller schools, to protect students’ privacy: each is shown as ED publishes it, never as a single figure.
