Summary

Dennis B O'Brien Elementary School is a public elementary school in Dover, New Jersey, serving grades PK-5 with a total enrollment of 295 students. The school is part of the Rockaway Township School District, which is ranked 205 out of 609 districts in the state.

Academically, Dennis B O'Brien Elementary School has consistently ranked in the middle range of New Jersey elementary schools, with mixed performance on state assessments compared to the district and state averages. In English Language Arts, the school's proficiency rates are generally lower than the district and state, while in Mathematics, the proficiency rates are also lower. The school's 5th-grade Science proficiency rates are significantly lower than the district and state. Interestingly, the nearby Birchwood Elementary School and Catherine A Dwyer Elementary School, which are also part of the Rockaway Township School District, generally perform better than Dennis B O'Brien Elementary School on academic measures.

The school has a diverse student population, with subgroups including Female, Male, Asian, Hispanic, and White students. The school's special education students are ranked relatively low, while its low socioeconomic status (SES) students are ranked relatively high, suggesting the school is able to support these students effectively. However, the school's chronic absenteeism rate has been increasing, which is a concern as it can negatively impact student learning and academic achievement. Overall, Dennis B O'Brien Elementary School appears to be a middle-performing school within the Rockaway Township School District, and could potentially benefit from learning from the higher-performing schools in the district to improve its academic outcomes.
