Dear Parents, Guardians, and Students,

Keystone Exams: Students will be taking all Literature, Biology, and Algebra Keystone Exams digitally this year. Students will be testing on laptops and in computer labs. Please make sure your student has their laptop during these exams.  Seniors do not participate in the Keystone Exam. 

Keystone Literature Schedule: Due to the large number of students taking the Keystone Literature Exam (May 11-12), a modified schedule will be used for each day.  We will run the 2 Hour Delay Schedule.  ALL STUDENTS, EXCEPT CO-OP AND FLEX LATE ARRIVAL STUDENTS, ARE STILL REQUIRED TO REPORT TO SCHOOL BEFORE 8:10 AM. Students who are taking the Keystone Literature Exam will test in their designated testing rooms until 10:10 AM.  Students who do not take the Keystone Literature will report to their homerooms for study hall until 10:10 AM.  Once testing concludes at 10:10 AM, all students will follow the 2 Hour Delay Schedule.  Testing for the Keystone Literature Exam will occur on May 11-12, 2026.

CO-OP Students and Flex Late Arrival Students: CO-OP Students and Flex Late Arrival Students will follow the 2 Hour Delay Schedule as they would on a day with a weather delay.  CO-OP Students shall make arrangements in advance with their employers regarding any schedule changes on May 11-12, 2026.
