Summary

Middlesex County STEM Charter School is an elementary school located in Perth Amboy, New Jersey, serving students from kindergarten to 8th grade with a total enrollment of 571 students. The school is part of the Middlesex County STEM Charter School District, which is ranked 533 out of 609 districts in New Jersey and has a rating of 1 out of 5 stars by SchoolDigger.

While the school has some notable strengths, such as its strong performance for African American students, ranking in the top 110 out of 463 New Jersey elementary schools for this subgroup, the school's overall academic performance is significantly lower than the state averages and the performance of nearby traditional public schools like Robert N. Wilentz Elementary, Lafayette Estates Elementary, and James J. Flynn Elementary. The school's proficiency rates in English Language Arts and Mathematics are consistently low, with the highest proficiency rate being 45% in 6th and 7th grade ELA.

Additionally, Middlesex County STEM Charter School faces challenges with high chronic absenteeism rates, ranging from 14.9% to 18.3% over the past few years, which is significantly higher than the state average and the rates of nearby schools. The school also has lower spending per student and higher student-teacher ratios compared to nearby schools, suggesting potential resource disparities that may be contributing to the school's academic struggles. Addressing these systemic issues and ensuring equitable access to resources could be crucial steps in improving the school's performance and supporting the learning and development of all its students.
