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. These exams are state-wide assessments, and its data is used to inform educators on many different levels regarding the education that is provided to our children across the state. These standardized tests also give all members of your child’s team a data point to show growth in ability to perform within a standardized assessment environment. It provides your child with assessment knowledge, perseverance, and practice with assessment-taking abilities.

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

Spring 2026 Keystone Exams

The Spring 2026 Session of the Keystone Exams will be held May 11–20, 2026 and will begin promptly at 8:30 am on each testing day. 

Homeroom attendance will occur during the testing session. We have allotted approximately 86 minutes for each testing module.  Additionally, all students will have extended time should they not finish at the end of the 86 minutes.

For the Spring 2026 testing window and beyond, Pennsylvania has transitioned from paper exams to mandatory online testing. To better support students taking these exams, testing will take place in classroom settings that provide a more focused and appropriate environment. As a result, Radnor High School will implement a delayed opening schedule for all non-testing students over six days. This approach ensures that students taking these high-stakes exams have the space, time, and resources they need to be successful. 

At the conclusion of the Keystone exams, students will report directly to their regularly scheduled classes. If a student misses class due to their participation in a Keystone Exam, the absence will be excused. Students should check Schoology to see what work they missed and reach out to their teacher with questions.

Transportation

Transportation will run in two phases: buses will first bring testing students to school for the Keystone Exams, followed by transportation for non-testing students later in the morning.
 

Devices

For students using their own devices, we will meet with them in advance to ensure the required software is properly installed and ready for testing. If a student with their own device is not able to load the software, a device will be provided for them on testing days.
