The Pennsylvania Classroom Diagnostic Tools (CDT) is a set of online assessments, divided by content areas (Literacy, Mathematics, and Science), and is designed to provide diagnostic information to guide instruction in order to support intervention and enrichment. The CDT reporting system is fully integrated in the Standards Aligned System (SAS). It assists educators in identifying student academic strengths and areas in need of improvement, and provides links to classroom resources. The CDT is a computer adaptive test (CAT) and depending upon how the student responds to the first few items; the next set of items will adjust to the student’s instructional level. The diagnostic reports feature easy-to-follow links to targeted curricular resources and materials, including units and lesson plans found within the SAS system. Students receive approximately 48–60 items per test depending upon their response pattern. The CDT is an un-timed test and it can be scheduled over multiple days. The CDT is available to districts at no cost.

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.

• Available for use in the classroom throughout the school year on a voluntary basis.
• Provide real-time results, ensuring valid and reliable measures, of students’ skills with links to Materials and Resources in SAS.
• Highlight student strengths and areas of need thus becoming part of the discussions between teachers, parents/ guardians, and students to set individual learning goals.
