Why do I need approval to use Cognition Measures?

The NIH Toolbox was developed and is made available in accordance with the Standards for Educational and Psychological Testing developed jointly by the American Psychological Association, American Educational Research Association and the National Council on Measurement in Education (1999). Consistent with these standards, test users must have the appropriate knowledge, skills, training and experience to responsibly use NIH Toolbox measures.

“Test users” are those persons responsible for the selection, administration, scoring and interpretation of tests and the communication of results. The NIH Toolbox Cognition measures are considered C-Level tests (like the Weschler scales, for example). C-Level tests require a high degree of expertise in test interpretation, and thus should only be provided to a User with state licensure or certification to practice in a field related to the request, or a doctorate degree in psychology, education, or a closely related field, with formal training in the ethical administration, scoring, and interpretation of clinical assessments related to the intended use of the assessment.

Any users of C-Level assessments must be supervised by one or more users with C-Level qualifications, which must have been provided in advance per this process.
