Validity Evaluations

edCount specializes in applying an argument-based approach to validity evaluation, designed to help clients articulate and evaluate the meaning of their assessment scores in the context of their entire education system. After helping clients articulate a theory of action describing their assessment system's purpose and underlying logic model, we develop a plan to assess the validity of the model. This may suggest a variety of different studies that are necessary to establish evidence of the validity of an assessment score's meaning and use. edCount's involvement may end with developing a plan or we may conduct any one of the many types of studies deemed necessary to establish validity in the context of the assessment system.
