Summary

Hartshorn School is a public elementary school located in Short Hills, New Jersey, serving grades K-4 with a total enrollment of 428 students. It is part of the Millburn Township School District, which is ranked 14th out of 609 districts in New Jersey and is rated 5 out of 5 stars by SchoolDigger.

Hartshorn School consistently ranks among the top elementary schools in New Jersey, with a statewide ranking between 8th and 62nd out of over 1,300 schools over the past 10 years. Its students demonstrate exceptional academic achievement, with proficiency rates in English Language Arts and Mathematics significantly exceeding the state averages. The school's academic performance is particularly impressive for its Asian student population, which ranks among the top 16-33 schools in the state for this subgroup. However, the school's performance for its White and Special Education student subgroups is relatively lower, ranking in the 100s-300s out of over 1,000 schools.

While Hartshorn School and the Millburn Township School District are among the top-performing in the state, the nearby Summit Public School District also has several highly-ranked elementary schools, such as Washington Elementary School and Lincoln-Hubbard Elementary School. This suggests that the broader region is home to a concentration of high-performing public schools. However, Hartshorn School's increasing chronic absenteeism rates and the need to address performance gaps for certain student subgroups present opportunities for further improvement and growth.
