The current paper conveys guidelines for personality assessment developed by a work group formed by the Society for Personality Assessment (SPA), which are intended to serve as an aid for best practices specific to personality assessment for professionals, and a source of information for consumers and policy makers. The guidelines were developed after a careful and systematic review of the literature on personality assessment and examination of practice patterns, and were refined through multiple rounds of input from stakeholders including members of SPA and other professionals routinely conducting personality assessment. The guidelines address the scope of personality assessment and current practice trends, minimum education and training qualifications, ethical practices, diversity considerations, assessment procedures, and appropriate applications. By following these guidelines and other established professional standards, psychologists can help ensure that they practice ethically, competently, with appropriate attention to diversity, and to the highest standards of the profession. These guidelines can function as a resource for educators and supervisors of personality assessment. Additionally, the guidelines will serve as a benchmark for best practices in personality assessment and, as such, represent a first step in what is hoped to be an evolution of ever improving personality assessment standards of practice.
