Summary

Klockner Elementary School is a public elementary school serving grades PK-5 in Hamilton, New Jersey, with 275 students. The school is part of the Hamilton Township Public School District, which is ranked 473 out of 609 districts in the state and has a 1-star rating from SchoolDigger. Klockner Elementary has consistently ranked in the bottom quarter of New Jersey elementary schools over the past decade, with a current statewide ranking of 900 out of 1,347 schools and a 2-star rating.

Klockner Elementary faces significant challenges, including low academic performance, high chronic absenteeism, and a socioeconomically disadvantaged student population. The school's performance on state assessments is consistently below the state and district averages, with only 51.2% of 3rd graders proficient or better in ELA and Math in 2024-2025, compared to 44.9% and 49.8% statewide, respectively. Klockner also has high chronic absenteeism rates, ranging from 14.9% to 19.1% over the past few years, significantly above the state average of around 40%.

Interestingly, Klockner Elementary's performance is generally lower than the other public elementary schools in the immediate vicinity, such as Morgan Elementary School, Langtree Elementary School, and Greenwood Elementary School, which all have higher test scores and serve a less economically disadvantaged student population. The school's declining statewide ranking and performance gaps between student subgroups suggest that Klockner may need to re-evaluate its instructional practices and strategies for supporting student engagement and achievement.
