Calculating Black Cager Academic Index for Philadelphia Public/Charter High Schools

The Black Cager Academic Index is designed to help parents, students and student-athletes make informed High School enrollment decisions. The Black Cager Academic Index scores allows parents to compare and contrast the extent to which schools are producing students that satisfy the requirements of the Pennsylvania Department of Education (PDE). The Black Cager Academic Index is based on the Keystone Exam score results for each school.

The Keystone Exams are state-mandated end-of-course assessments in Algebra I, Biology and Literature. Each Keystone Exam is divided into two parts called modules. Student scores are based on the total points earned from the two modules combined. The scores are then broken down into the following categories: Advanced, Proficient, Basic and Below Basic. Students must score in the Advanced or Proficient range to show mastery of the content. Basic and Below Basic scores do not demonstrate mastery and are considered failing scores.


Students must take a Keystone exam at the end of each of the Keystone-assessed courses. (i.e.: At the end of the year, students in Biology will take the Biology Keystone Exam.) Per state law, the Pennsylvania Department of Education requires schools to put the highest level of proficiency level for each Keystone exam on the student’s transcript.

Algebra 1 – Black Cager Academic Index Calculation
(%Advanced * 2) + (% Proficient) – (% Basic) – (% Below Basic * 2)

Biology – Black Cager Academic Index Calculation
(%Advanced * 2) + (% Proficient) – (% Basic) – (% Below Basic * 2)

Literature – Black Cager Academic Index Calculation
(%Advanced * 2) + (% Proficient) – (% Basic) – (% Below Basic * 2)

Individual HS – Black Cager Academic Index
(Algebra 1 Index + Biology Index + Literature Index)/3

If 100% of the students score in the Advanced range for Algebra 1, the school’s Black Academic Index for Algebra 1 will be 200.

(100 * 2) + (0) – (0) – (0 * 2) = 200

If 100% of the students score in the Below Basic range for Algebra 1, the school’s Black Academic Index for Algebra 1 will be -200.

(0 * 2) + (0) – (0) – (100 * 2) = -200

Thus, the range for the Black Cager Academic Index for each of the three (3) subject areas is 200 to -200.

The range for the Black Cager Academic Index for the High School as a whole is calculated by adding the three (3) subject area scores together and dividing the total by three.

Thus the range for the Black Cager Academic Index for each of the Public/Charter High School is also 200 to -200.

The scores will be ranked and accssible to any parent, student or student-athlete considering enrollment in or a transfer to any Philadelphia Public/Charter school.

  1. An excellent tool to let any exceptional athlete know, your academic knowledge is equally important. Applying oneself, accordingly, will prevent any surprises once applying for higher education.
