Summary:
Erial’s list includes two schools in separate districts: James W. Lilley Elementary School, serving kindergarten through Grade 5, and Timber Creek Regional High School, serving Grades 9–12. Their latest supplied test results vary considerably by grade and exam, but most are below state results. Across 16 matched school-and-test results, the average gap widened from 12 points below the state in 2024–2025 to 14 points below in 2025–2026—the clearest overall concern in the area’s results.
Timber Creek stands out on the Grade 11 NJGPA: ELA essentially matched the state at 76% for both, and mathematics was 65% versus 61%, a 4-point advantage. Lilley’s relative high point was Grade 4 mathematics, at 41%, 6 points below the state—the school’s smallest state gap among its reported results. The largest gaps were Timber Creek Algebra I End of Course, at 12% versus 40% statewide (28 points below), and Lilley Grade 3 ELA, at 23% versus 48% (25 points below). These results involve different grades and exams, so they do not establish a direct academic ranking between the schools.
Results over time were uneven: Timber Creek’s Geometry End of Course proficiency fell 19 points to 26%, widening its state gap from 11 to 25 points; Lilley Grade 3 ELA fell from 30% to 23%, while the state rose from 45% to 48%. A notable exception was Lilley Grade 4, where ELA and mathematics improved relative to the state. SchoolDigger rankings were fairly steady: Timber Creek moved from the 37th to the 39th percentile between 2023–2024 and 2025–2026, while Lilley moved from the 24th to the 23rd. In 2024–2025, Timber Creek’s student-teacher ratio was 13.1 and Lilley’s was 11.1; free/reduced lunch eligible figures that year were 44% and 52%, respectively. These are useful context, not explanations for test results.
