Enrollment stability & demand — 2024-25
Two complementary signals: retention (do students stay once enrolled?) and demand (are families choosing the school?). Read against the Lassen County baseline — the demographic tide is moving every CA HS, so a school's gap vs. county is the actionable signal.
Enrollment growth is beating Lassen County (+57.1% vs. +21.6%), but 28 of 79 students didn't maintain continuous enrollment. Why are families leaving once enrolled?
28 of 79 students who enrolled at Mt. Lassen Charter this year didn't maintain continuous enrollment (35.4% non-stability). Mid-year transfers, dropouts, and other exits are all counted.
Stability by student group
Nearest peer high schools
Source: California Department of Education, Stability Rate 2024-25. Benchmarks limited to non-virtual public & charter HS with ≥100 cumulative enrollees so by-design-high-churn continuation schools don't dominate the bottom of the distribution. Cumulative enrollment counts every student on the rolls during the year, so it can exceed peak-day enrollment.
Chronic absenteeism — 2024-25
Share of students missing 10% or more of expected attendance — the leading indicator that often precedes the demand decline shown above. Families disengaging tend to raise absenteeism first, then formally leave. Basis: grades 9–12.
Low and stable absenteeism — students are engaged and showing up. The leading indicator is healthy.
Source: California Department of Education, Chronic Absenteeism 2024-25. Benchmarks limited to non-virtual public & charter HS with ≥100 eligible students. CDE didn't publish a usable 2019-20 file (COVID).
SBAC academic outcomes — grade 11, 2025
Share of grade-11 students meeting or exceeding the California standard on Smarter Balanced ELA and Math. This is the academic-readiness signal that pairs with UC Reach (post-grad outcomes), stability (retention), and absenteeism (engagement). Note: statewide median Math is only ~20% — a school at 20% isn't an outlier; one at 45%+ genuinely is.

District financial profile — Fort Sage Unified (FY2020)
From 4 years of NCES F-33 filings (the federally-mandated district finance survey). Public schools don't have their own books — the district does. These figures show the financial scale, revenue dependence, instruction-vs-overhead mix, and long-term debt that shape what a school can sustain.
Local: 14.4%
Federal: 10.9%
Source: NCES F-33 Annual Survey of School System Finances (Urban Institute Education Data API). Latest year currently published: FY2020. F-33 is a district-level federal filing — it reflects the Fort Sage Unified as a whole, not this individual school's books. Revenue mix shows where the district's dollars come from (state aid dominates in CA via LCFF). Instruction share is current expenditure on instruction ÷ total current expenditure (national benchmark ~60%). Long-term debt is end-of-year outstanding (mostly facilities bonds).
