Periodic assessment and scrutiny of the discipline's measurement practices, instruments, and research findings are necessary to provide clarity and direction by revealing what we know, how we know it, and where the knowledge gaps exist. Reflective reviews have produced ample appraisals of the theory, research, and methods employed in the conduct of instructional communication scholarship. The scope of the present effort is twofold and includes both description and critical assessment and evaluation of 21 instruments published post 2004 in journal outlets that traditionally feature instructional communication research. The reliability, validity, and usefulness of each measure are examined, measurement practices are critiqued, and problems are identified. The manuscript concludes by offering several recommendations for measurement in instructional communication research.
