What changed?

These measures follow the same rule on every school page, not a ranking of this school’s biggest changes. Each row names its evidence dates; trend rows do not describe every year in between.

These are descriptive measures from statewide NJDOE datasets, not a quality rating or an explanation of cause. Proficiency, attendance, and graduation figures use All Students; subgroup patterns may differ.

Enrollment over time

In 2025-26 it enrolled 827 students. That is 630 more than in 2014-15 (197) — the school has grown. It peaked at 890 in 2024-25.

How much the mix changed

Between 2021-22 and 2025-26 the makeup of this school barely moved.

That’s the smallest shift among the district’s three high schools — and the smallest of 19 across Mercer County. That roughly tracks the district overall (7) — a district-wide change more than a school-specific one. The biggest moves, in percentage points:
Black −3·Hispanic +1.8·Two or more +1

The index is half the sum of every group’s change in share, on a 0–100 scale (how it works). It is computed from the same counts as the makeup chart above — source: NJDOE Fall Enrollment. Compare any two years in the explorer →

Free or reduced-price lunch

In 2025-26, 64.6% of students were certified for free or reduced-price lunch.

Share of students certified for free or reduced-price meals, through a household application or an automatic match. The lighter lines show the district overall and the district high schools, for comparison. Years the state did not report are shaded. Some districts serve free meals to every student under the Community Eligibility Provision. Those districts often stop collecting household income forms, so their reported share can run below the number of low-income students they enroll. Source: NJDOE Fall Enrollment.

Test scores

On the NJSLA — New Jersey’s state test — here is how students have scored over recent years and by grade. (New Jersey reports student-growth scores only through grade 8, so they are not available for high schools.)

English language arts: 10.4% met or exceeded expectations in 2024-25 (state 53%), down from 12% in 2021-22.

In each panel the flat line is the proficiency boundary: levels 4–5 (met or exceeded) fill the area above it, levels 1–3 below — so a smaller reported share in levels 4–5 makes the area above the line shrink (it isn’t a misleading upward slope). Light = level 1 (did not yet meet expectations), dark = level 5 (exceeded); the % marks the proficient share at the first and last points. The first set of panels follows each grade across the years; the second lines up aggregate grade results one grade higher each year. It approximates a class cohort, not linked individual students. Growth is the median Student Growth Percentile (50 = a typical year), reported only through grade 8. The NJSLA was not given in spring 2020 and was disrupted the next year.

Chronic absenteeism

In 2024-25, 51.8% of students were chronically absent — missing at least 10% of school days — up from 39.2% in 2018-19.

† New Jersey says these years are not comparable with the ones beside them

  • 2020-21 — in-person and remote days differed. The requirement to report status in meeting annual ESSA targets for 2020-2021 was waived. As a result, NJDOE will not report state averages and whether state averages were met for 2020-2021. Additionally, because the number of days students spent in in-person and remote learning environments during the school year differed, the NJDOE recommends caution in comparing 2020-2021 attendance data between schools and districts and to prior or future school years. NJDOE 2020-21 workbook notes sheet.

2019-20 is blank because New Jersey collected no attendance data that year, not because nobody was absent. The requirement to report on chronic absenteeism and related accountability measures for the 2019-2020 school year was waived. As a result, NJDOE will not report on chronic absenteeism and other attendance data for 2019-2020. Tables showing attendance data will be hidden in the 2019-2020 reports. NJDOE 2019-20 workbook notes sheet.

Chronic absenteeism — the share of students who missed 10% or more of the days they were enrolled (roughly 18 days across a full school year). The lighter lines show the district overall and New Jersey, for comparison. The current workbook publishes four years of this measure; the years before them come from each earlier year’s own workbook, which publish the same figures wherever the two overlap. The statewide line starts in 2021-22, because that is the first edition in which NJDOE printed a statewide rate beside each school’s own. Points from 2018-19 and earlier are matched to this school by its state code; New Jersey’s organization record only reaches back to 2020-08-11, so for those years the code is verified and the identity behind it is not.
