Pennsylvania schools are under pressure to meet academic growth and achievement standards set forth by the Commonwealth. Due to these high-stakes, schools are always looking for ways to improve academics to not only meet the needs of students, but also the expectations put forth at the state level. The proposed research study examined if a differences exist on Keystone Exam performance level scores in secondary schools in PA implementing Schoolwide Positive Behavior Intervention and Supports (SWPBIS) and those not implementing SWPBIS. PA secondary schools that are implementing SWPBIS were selected using the Pennsylvania Positive Behavior Supportive (PAPBS) Network recognition list from the 2018-2019 school year (PAPBS, 2019). Each year the PAPBS Network posts what school in PA have successfully met the network's criteria of implementing SWPBIS. Keystone Exam performance level data was retrieved from the Pennsylvania Department of Education's website (Pennsylvania Department of Education, 2019). The scores were retrieved for the 2019 school year, the most recent scores available. The results of the study showed no statistically significant differences in Keystone Exam performance level scores in secondary schools in PA implementing Schoolwide Positive Behavior Intervention and Supports (SWPBIS) and those not implementing SWPBIS.
