Pennsylvania System of School Assessments, commonly called PSSAs are No Child Left Behind Act related examinations which were administered from 2003 through 2012, in all Pennsylvania public high schools. The exams were administered in the Spring of each school year. The goal was for 100% of students to be on grade level or better in reading and mathematics, by the Spring of 2014. The tests focused on the state's Academic Standards for reading, writing, mathematics and science. The Science exam included content in science, technology, ecology and the environmental studies. The mathematics exam included: algebra I, algebra II, geometry and trigonometry. The standards were first published in 1998 and are mandated by the Pennsylvania State Board of Education.
