Classroom Strategies Assessment System [CSAS]



The Classroom Strategies Assessment System [CSAS] has been extensively developed and validated over the past eight years using modern test development methods, user input, pilot testing, and implementation in public schools. The CSAS development has been supported by funding from federal and private foundations.

Effective Instruction Research

  • Grounded in over 60 years of effective instruction literature that covers instruction and classroom behavior management
  • Incorporates effective practices from three models: Direct Instruction, Differentiated Instruction, and Constructivist-based teaching models. Also examines the promotion of metacognition and feedback processes.

Expert, Principal, Teacher, and School Personnel Input

  • Researchers, Teachers, and other experts in instruction and classroom behavior management provided input on the content and validity of the CSAS
  • Teachers, Principals, and other school personnel from local school districts reviewed the Classroom Strategies Assessment System and gave feedback on its content and process

Pilot Testing

  • Classroom Strategies Assessment System was pilot tested in over 500 classrooms and 1500 observed lessons
  • Pilot tests included Principals, Teachers, School Personnel and a national board of experts

Validity and Reliability Studies

The Classroom Strategies Assessment System evidences good reliability and validity based on the 2014 Standards for Educational and Psychological Testing
  • Evidence of Construct Validity includes:
    1. Extensive consumer and expert input and pilot testing on domains, dimensions and items
    2. Use of advanced statistics methods to test domains and dimensions within classroom observations
  • Evidence of Reliability includes:
    1. Internal Consistency
    2. Test-Retest Reliability
    3. Inter-Observer Reliability
    4. Freedom from Item Bias
  • Evidence of Validity includes
    1. Construct Validity
    2. Predictive Validity to Statewide Student Mathematics and Language Arts Testing
    3. Concurrent Validity with the Classroom Assessment Scoring System (CLASS)
    4. Divergent Validity with the Classroom Assessment Scoring System (CLASS)
    5. Concurrent Validity with the Danielson Framework for Teaching
