Overview

Valid and reliable assessments result from the application of systematic development efforts by both content experts and psychometricians. This is a multistep process that includes carefully defining the construct to be measured, developing a test blueprint aligned with the purpose of the assessment, thoughtful application of the art and science of item writing, and empirical data collection to support item and test validity. Research in test development is concerned with improved methods to enhance the validity and reliability of assessments.
