Pennsylvania Keystone Exam for Biology


Keystone exams are Pennsylvania’s end of course assessments in specific content areas. The Keystone Biology Exam consists of two test modules that take 1 to 1.5 hours each. Both modules will be administered during one school day. The test contains multiple choice questions and open ended responses that are designed to assess student comprehension of Biology. All students must take the Biology Keystone Exam to satisfy Federal testing requirements. Pennsylvania students in grades 9 and below must pass Keystone Exams to qualify for a high school diploma.




  • Juniors will take the Biology Keystone Exam this December 2013 during the testing window December 2nd through December 13th.
  • Sophomores who have not previously taken the Biology Keystone Exam or opt to retake the Biology Exam will test during the December 2-13th testing window.
  • Freshmen (and any student currently enrolled in Biology) will take the exam during the testing window May 12th through 24th, 2014 near the completion of their Biology course.



Tests will be administered at Conestoga High School during the school day.
