In 2025-26 it enrolled 257 students. That is 286 fewer than in 1998-99 (543) — the school has shrunk. It peaked at 744 in 2002-03.

The largest group in both 1998-99 and 2025-26 was Black students — 94% then, 66% now.

In 2025-26, 75.1% 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 elementary 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.
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 school’s median growth percentile was 41 in English and 48 in math — NJ calls this “typical” growth.
English language arts: 57.1% met or exceeded expectations in 2024-25 (state 53%), up from 46.2% in 2022-23.

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.

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.
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, 10.1% of students were chronically absent — missing at least 10% of school days — down from 33.9% in 2021-22.
† New Jersey says these years are not comparable with the ones beside them
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.

2021-22 – 2024-25 · the ESSA record
New Jersey has published a summative rating for Sir Isaac Newton Elementary School in one school year under ESSA. The rating is a percentile inside a group of schools NJDOE considers comparable — where the school placed among them, not a score and not a grade.
There is one rating here, for 2024-25. One rating is a reading, not a direction.

Inside 2024-25 · what produced the most recent rating
For 2024-25 New Jersey weighted five indicators to add to 100 and gave this school 47.39 of those 100 points. It then ranked that total against the 1,659 New Jersey schools it grouped as Elementary for the year, which puts this school above 44.99% of them. That ranking is a place in a line-up of similar schools, not a grade and not a status.
Each bar’s light track is the points that indicator was worth at this school; the filled part is the points it earned. NJDOE converts each result into a 0–100 indicator score — built from the standardised results of each student group large enough to report, not from the school-wide number alone — then multiplies that score by the weight. The tracks add to 100 and the filled bars add to the summative score, within the publisher’s own rounding.

| ELA proficiencystudents who met or exceeded expectations on the state ELA test | 57.1% | 66.2 | 17.5% | 11.58 |

NJDOE published no result for Progress toward English proficiency. Below the state’s minimum group size nothing is reported at all, and an indicator with no result carries no weight — the remaining indicators were rescaled to add to 100 without it. Four-year graduation rate, Five-year graduation rate, Six-year graduation rate, High school persistence are not part of the calculation for a school NJDOE groups as Elementary.
NJDOE’s Targeted Summary published no student-group flag for this school for 2026-27.
These are policy-defined values: which indicators count, and how much each counts, is set by New Jersey’s ESSA plan, not by any measure of school quality. The weights are specific to this school — an indicator that drops out shifts weight onto the rest, so the same indicator is worth different points at different schools. The workbooks measure 2024-25 and were published on April 2, 2026; 2024-25 was not a year New Jersey identified schools for comprehensive or targeted support, so these files carry no CSI or ATSI status. These weights are 2024-25’s: the indicator set and the weighting have both moved across the eight editions above, and for some school types they moved in this one.
