A Brief History

#3 Charter High School in PA!

Mastery Charter School Thomas Campus is a an eleven year old independent charter based on the model developed by Mastery Charter High School -- Lenfest Campus (founded in 2001). Mastery’s mission is to prepare urban youth for success in higher education and the global economy. In fall 2005 the School District of Philadelphia invited the original Mastery school to convert the District’s struggling Thomas Middle School in South Philadelphia into a charter school serving grades 7-12.

In fall 2005, Mastery converted the Thomas school as an independent charter school.  The existing students remained but Mastery replaced the staff and implemented its program.   Since that time, the school has added a new high school grade each year.  In the 2009-10 year, Thomas added its first senior class, held its first graduation and had its first graduates enroll in college.

The turnaround has been very successful. Before the turnaround the school performed below the School District PSSA average.  Thomas campus students now surpass their District peers by more than 30 percentage points in both 8th grade reading and math.  Since the school’s turnaround, 8th grade scores have increased 46 percentage points in math and 58 points in reading.  In fact, the Thomas Campus has closed the achievement gap with their state-wide peers and score higher than the PA average in 8th grade reading and math.  At the 11th grade, Thomas students are performing at or within a few points of the PA average in both reading and math.

In 2011, Mastery Thomas received an Effective Practice Incentive Community Silver Award— a U.S. Dept of Education funded program to identify the charter schools who have attained the highest value added student achievement levels.  The Thomas campus was one of only 23 schools recognized nationally.

We are most proud of the college-going culture that has been created at Thomas.  100% of the first  and second graduating classes were accepted to college.  Two thirds of students are attending four year colleges, including University of Pennsylvania and Columbia University.
