Classroom Diagnostic Tool and Firefly
CDT on SAS
The first place to look for information and resources on Classroom Diagnostic Tools is on PDE's SAS Portal. Classroom Diagnostic Tools (CDT) are based on content assessed by the Keystone Exams and the Pennsylvania System of School Assessment (PSSA). Although not a predictor for PSSA and Keystone Exam performance, CDTs provide a snapshot on why and how students may still be struggling or exceeding grade and/or course Eligible Content. The CDT data, along with other data, informs instruction in a timely and efficient manner.
PA CDT Training and Resource Site
The PA CDT Training and Resource site contains a collection of instructional videos, presentations and documents to learn about what to do before, during and after administering the CDT.
