HARRISBURG – The Pennsylvania System of School Assessment will be two weeks next year, down from three, and moved to later in the school year, giving students a few more weeks of learning beforehand. Changes in place this year include reducing testing by two days, removing math and English language arts sections, and requiring fewer science questions. Gov. Tom Wolf says he’s responding to concerns of students, parents, and teachers. The Wolf Administration notes the Keystone Exams, which test knowledge at the end of courses, is being delayed, and that career and technology education students now have alternative ways to show they are proficient.
