Summary:

Mastery Charter School John Wister Elementary is the sole public charter elementary school serving grades K-5 in this area, with a total enrollment of 497 students. Despite spending more per student than the state average, this school has consistently ranked in the bottom 20% of Pennsylvania elementary schools over the past 3 years and struggles with significantly below-average proficiency rates on statewide assessments in both Math and English Language Arts.

The school's extremely high rate of 99.4% of students qualifying for free or reduced-price lunch indicates that it serves a predominantly low-income community. While the school has a relatively small student-teacher ratio of 16:1, this smaller class size does not appear to be translating into better academic outcomes. The school's consistently low performance on standardized tests suggests the need for more effective instructional strategies and interventions to improve student learning.

Overall, Mastery Charter School John Wister Elementary faces significant challenges in providing a high-quality education to its students, as evidenced by its poor ranking and test scores compared to state averages. Addressing the unique needs of its high-poverty student population and implementing more successful teaching methods will be crucial for the school to improve academic achievement.
