Peter Langer

Principal, Mastery Charter School Thomas Campus High School
Mastery Charter Schools
2018 Neubauer Fellow

“I serve as a principal because I believe every student in Philadelphia deserves an outstanding education. I became a Neubauer Fellow because I hope to learn new skills to improve my leadership so all students can receive that outstanding education.”

Peter has served as the principal of Mastery Charter Thomas High School since 2019. In his first year of principal at Thomas High School, student retention increased from 91% to 96% and student median growth on the NWEA Map (a nationally normed test) increased 24 percentiles. Further, the school increased the percentage of students with average daily attendance of 90% or higher from 73.3% to 76.5%, increased the Median Conditional Growth percentile on Northwest Evaluation Association (NWEA) measure of academic progress (MAP) reading from the 45th to 56th percentile, and increased the Median Conditional Growth percentile on NWEA MAP math from the 39th to 76th percentile.

 

Prior to his role at Thomas, Peter was principal at Mastery Simon Gratz – Lower School (2012-2019). Under Peter’s leadership, Gratz was the third highest-rated comprehensive, open-enrollment high school in Philadelphia according to Pennsylvania’s 2015-2016 School Performance Profile. In 2013-2014, Gratz achieved the largest increase of any Philadelphia school on Pennsylvania’s school rating system. From 2011 to 2018, the school doubled Keystone proficiency rates in algebra, biology, and literature, and increased student attendance from 77% to 90%. These are tremendous gains considering that the school was one of the lowest-rated schools in the city and was on Pennsylvania’s persistently dangerous school list in 2010-11, prior to Peter’s arrival.

 

Peter has been an educator since 2006. Prior to becoming a principal, Peter served as a middle school math and science teacher and assistant principal. Peter grew up in Buffalo, New York.
