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 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.
