Source: federal Civil Rights Data Collection (CRDC 2020-21). Volume — not score — is what's reported here. A higher count means more students at this school are entering the college admissions pipeline. Note: 2020-21 was COVID-disrupted; some districts (especially those that stayed remote longer) report unusually low or zero takers.

🏛️ Federal Title I context

Mixed-income school

Below Title I eligibility threshold (FRPL < 35%)

27.4%
FRPL rate — % of students who qualify for the federal Free or Reduced-Price Lunch program. This is the underlying federal income-eligibility signal Title I designations are computed from (ESEA Sec. 1113).
0% (no FRPL) 35% TA · 40% Schoolwide 100% (universal FRPL)

25-34% of students qualify for free/reduced lunch. Below the federal Title I threshold but a meaningful share of the population is income-eligible for free lunch.

Source: NCES Common Core of Data, free/reduced-price lunch eligibility. The actual Title I designation is a district decision and may differ from eligibility — but the federal eligibility math is what we show here. We don't claim to assert whether the district formally chose to enroll this school in Title I.

in-state tuition/yr · $28,320 out-of-state

The in-state tuition gap is the flagship's biggest draw — most in-state families pay far less than the out-of-state sticker. Average net price after aid runs about $14,831/yr. Admission odds depend on your student's GPA and test scores, not which high school they attend.

Chronic absenteeism

Share of students absent 15+ days
1.6%
Below 10% — strong attendance culture. Chronic absence is a leading indicator of dropout and disengagement; a low rate signals families staying connected to the school.
Students absent 15+ days
27
Federal definition: absent (excused or unexcused) for at least 15 of ~180 school days — about 10% of the school year.

Why this matters to enrollment: A low chronic-absence rate is the cleanest school-level signal of strong family connection, classroom culture, and student engagement — all upstream drivers of enrollment stability. For school leaders: an Enrollment Trend Audit traces this dynamic forward →

Counselor capacity

Around the US median. Counselors are stretched but functional.
Counselor FTE

Full-time-equivalent school counselors on staff.

Full-time-equivalent classroom teachers.

Source: U.S. Department of Education, Civil Rights Data Collection 2020-2021. Counselor ratio = the school's most recent total enrollment ÷ counselor FTE. The American School Counselor Association (ASCA) recommends a 250:1 maximum; the US national median across schools with on-staff counselors is roughly 430:1.

Enrollment trend & projection

Grade 12 went from 352 in 2021 to 382 in 2024 — over 3 years.
+8.5%

Total enrollment + grade 12, NCES Common Core of Data (2021–2024).

If the recent trend holds…

At its recent rate of +2.3%/year, projecting from 2024's 1,693 students:

2025
1,731
2027
1,810
2029
1,892

An extrapolation of the recent trajectory, not a forecast of the school's plans; ignores one-off shocks.

Revenue upside

At $9,451 per student in district revenue, the 199 students projected to be gained by 2029 represent ≈ $1,880,749/year in additional funding.

District total revenue ÷ enrollment, NCES F-33. Public funding largely follows enrollment, so a shrinking class is a recurring budget hit.
