Classroom Diagnostic Tool

  • 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.


    The Pennsylvania Classroom Diagnostic Tools (CDT) is a set of online assessments, divided bycontent area, designed to provide diagnostic information in order to guide instruction and remediation. The CDT reporting system isfully integrated in the Standards Aligned System (SAS). It assists educators in identifying student academic strengths, and areas in need of improvement, byproviding links toclassroom resources. The diagnostic reports feature easy-to-follow links to targeted curricular resources and materials, including units and lesson plans found within the SAS system. The CDT is available to districts at no cost. 


    The purpose of the CDT is toprovide information that will help guide instruction byproviding support to students and teachers. The CDT reports are designed toprovide apicture or snapshot of how students are performing in relation to the Pennsylvania Assessment Anchors & Eligible Content and Keystone Assessment Anchors & Eligible Content. The CDT goes beyond focusing only on What studentsshould know and beable to doat aparticular grade and/or course. It also provides a snapshot of How and Why students may still be struggling or extending beyond the grade and/or course Eligible Content. This valuable information istypically not identified through other types of assessments. Teachers, through the use of CDT reports, may access additional information through the Learning Progression Map. The Learning Progression Map allows teachers topinpoint where students are struggling along or extending beyond the learning continuum. The CDT helps identify, and provides suggestions, for “next steps” in student academic development
