Keystone Exams

The Keystone Exams are state-mandated end-of-course assessments in Algebra I, Biology and Literature. At the high school level, they are used to satisfy the requirements of the Pennsylvania Department of Education (PDE).  

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.

If you have questions about the administration or scheduling of Keystone exams, please contact Assistant Principal Gabriel Presley. If you have specific question about the Keystone exams, your child’s scores, the Pennsylvania Graduation Requirement, or the alternative pathways, contact your child's school counselor.
