The Assessment Science Lab is broadly focused on increasing the efficacy and efficiency of school psychological assessment. Our lab is interested in improving the instruments and processes used by school psychologists.

Thus far, our focus is three-fold with emphasis on (a) instrument psychometrics, (b) training of graduate students in assessment practices, and (c) emphasizing evidence-based assessment in schools.

If you are interested in our work, either as potential student or collaborator, please contact Dr. Farmer.


Dr. Farmer is an Assistant Professor with the School Psychology program at Oklahoma State University. His research investigates assessment processes in school psychology.
