Predictive Methodology

This analytic model is used for subjects that are assessed in non-consecutive or consecutive grades, including when students move from one assessment type to another:

  • PSSA Science in grades 4 and 8
  • Keystone Algebra I, Biology, and Literature
  • All CDT assessments
  • AP Biology, AP Calculus AB, AP English Language and Composition, AP English Literature and Composition, AP Psychology, AP Statistics, AP United States Government and Politics, and AP United States History
During the 2022-23 school year, ISAT assessments for English Language Arts and Math were administered in grade 11 instead of in grade 10 as in the past. In addition, some students that took these assessments in the 2021-22 school year while in grade 10 were not required to take the assessments while in grade 11 during the 2022-23 school year. For reporting and accountability purposes, the scores for this group of students were used as grade 11 scores for the 2022-23 school year alongside the grade 11 scores of students who were required to take the assessments. As a result, a different approach was needed for the 2022-23 analysis for the grade 11 assessments. For more information, refer to the Statistical Models and Business Rules document.
