Summary

Laboratory Charter School is a public charter elementary school serving 406 students in grades K-8 in Philadelphia, PA. The school is part of the Laboratory Charter School District, which is ranked 588 out of 606 districts in Pennsylvania and has a 0-star rating from SchoolDigger. Over the past decade, the school's statewide ranking has steadily declined, dropping from 17th in the state in 2011-2012 to 1463rd in 2024-2025.

The data paints a concerning picture of Laboratory Charter School's performance. The school significantly underperforms the state and district averages on standardized tests, with only 3.1% of students proficient or better in Math and 12% in English Language Arts in 2024-2025, compared to state averages of 41.7% and 48.5%, respectively. This academic underperformance is consistent across all grade levels. The school's dropout rates have also been high in recent years, reaching 1.6% in 2022-2023 and 1.4% in 2023-2024, which are significantly above the state average.

When compared to nearby district schools, such as Munoz-Marin Luis Elementary School and Bethune Mary McLeod School, Laboratory Charter School consistently underperforms on academic measures. The school's significant underperformance of certain student subgroups, such as African American, low-socioeconomic, and disabled students, also suggests that the school may not be effectively addressing the unique needs of these populations.
