Summary

Mosser Elementary School is a public elementary school in Allentown, Pennsylvania, serving grades PK-5 with a total enrollment of 568 students. The school is part of the Allentown City School District, which is ranked 550 out of 606 school districts in the state and has a 0-star rating from SchoolDigger.

Mosser Elementary School consistently ranks in the bottom 15% of Pennsylvania elementary schools, with significantly below-average performance on PSSA (Pennsylvania System of School Assessment) tests. In the 2024-2025 school year, only 18.8% of Mosser students were proficient or better in PSSA Math, compared to 41.7% statewide and 14.9% in the Allentown City School District. Similarly, only 15.8% of Mosser students were proficient or better in PSSA English Language Arts, compared to 48.5% statewide and 17% in the district. The school's performance is particularly low for certain student subgroups, such as female and male students, who ranked in the bottom 10% of Pennsylvania elementary schools in PSSA Math proficiency.

While Mosser Elementary School has a relatively high per-student spending of around $19,000 and a low student-teacher ratio, these factors alone do not appear to be sufficient to overcome the academic challenges faced by the school's student population, which is predominantly from low socioeconomic backgrounds. The school's performance is consistently lower than nearby Central Elementary, Jefferson Elementary, and Sheridan Elementary, which also serve high-poverty student populations but generally outperform Mosser on PSSA tests.
