This document is the first set of practice guidelines to be formally reviewed and endorsed by the AACN Board of Directors and published in the official journal of AACN. They have been formulated with the assumption that guidelines and standards for neuropsychological assessment and consultation are essential to professional development. As such, they are intended to facilitate the continued systematic growth of the profession of clinical neuropsychology, and to help assure a high level of professional practice. These guidelines are offered to serve members of AACN, as well as the field of clinical neuropsychology as a whole.
