Since the 2012–2013 school year, the General Keystone Knowledge Test Literature, Biology, and Algebra I VHS Exams have been available.
[5] The passing of Keystone Exams in Algebra I, Biology, and Literature were all a graduation requirement for all high school students.
Getting a score of "proficient" or higher was needed in order to pass the exam for a particular subject matter.
On February 3, 2016, Tom Wolf signed a bill from the Senate saying that it should no longer be a requirement for students to pass the exams in the desired subject areas.
That also ordered the government to halt the graduation requirement of the Keystone Exams for two years along with the "Project Based Assessment" system.
