In 2025-26 it enrolled 16,191 students across grades PK–12. That is 3,783 more than in 1998-99 (12,408) — the district has grown. Its biggest cohort is grade 8.
Students enrolled in each grade each fall, stacked to the total — so the top edge is total enrollment. Bands run from the lowest grade (light) to the highest (dark); a band that appears or disappears is a grade the school added or dropped. “Other” is students with no grade level (mostly special education), so the bands always sum to total.

In 1998-99, 52% of students were White. By 2025-26 the largest group was Asian, at 63%.

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

In 2025-26, 30.1% of students qualified for free or reduced-price lunch.
Share of students eligible for free or reduced-price meals. The lighter line shows Middlesex County, for comparison. Not reported by the state in some years (shaded). Since 2014, some districts provide free meals to all students regardless of household income, which can lift the eligible share. Source: NJDOE Fall Enrollment.

Growth measures how much students progressed over the year against peers who scored the same the year before — 50 is a typical year. In 2024-25, this district’s median growth percentile was 54 in English and 55 in math — NJ calls this “typical” growth.
English language arts: 67.6% met or exceeded expectations in 2024-25 (state 53%), down from 69.1% in 2021-22.
By grade, year to year
Each panel is one grade — watch its mix of levels shift across 2021–2024.
By grade cohort, lined up across years
Each panel lines up aggregate grade results one grade higher each year. It approximates a class cohort, but does not track individual students; enrollment can change.
Math: 58.7% met or exceeded expectations in 2024-25 (state 42%), up from 56.2% 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.

In 2024-25, 92.1% of students graduated within four years — down from 94.2% in 2020-21.
Four-year graduation rate — the share of a class that finishes within four years of entering ninth grade (New Jersey’s state calculation). The lighter line shows New Jersey, for comparison. New Jersey also reports a federal four-year rate (91.4% for 2024-25); the two use slightly different cohort rules. Source: NJ School Performance Reports, 2024-25.
In 2024-25, 12.3% of students were chronically absent — missing at least 10% of school days — up from 11.5% in 2021-22.
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 line shows New Jersey, for comparison. Source: NJ School Performance Reports, 2024-25.
