Validity and Reliability

Validity and Reliability

Content Validity includes gathering evidence to demonstrate that the assessment content fairly and adequately represents a defined domain of knowledge or performance.   The purpose of the link below is to provide guidance for collection of evidence to document adequate technical quality of rubrics that are being used to evaluate candidates. The link is to the Cato College of Education at UNC Charlotte. 

Validity Evidence Needed for Rubric Use and Interpretation (link)

To establish content-validity for internally-developed assessments/rubrics, a panel of experts will be used.  There are some limitations of content validity studies using expert panels (e.g., bias), but this approach is accepted by CAEP.  As noted by Rubio, Berg-Weger, Tebb, Lee and Rauch (2003),

Using a panel of experts provides constructive feedback about the quality of the measure and objective criteria with which to evaluate each item …. A content validity study can provide information on the representativeness and clarity of each item and a preliminary analysis of factorial validity.

GSC is committed to ensure the Validity and Reliability of all EPP created assessments used within the Education program.

The Chart below identifies the EPP created assessments and the review cycle. The chart will be updated as assessments are revised or additional assessments are createrd.
