title: A Standard of Knowledge for the Professional Practice of Toxicology.
abstract: BACKGROUND
  Employers, courts, and the general public judge the credibility of professionals based on credentials such as academic degrees, publications, memberships in professional organizations, board certifications, and professional registrations. However, the relevance and merit of these credentials can be difficult to determine objectively. Board certification can be a reliable indicator of proficiency if the certifying organization demonstrates, through regularly scheduled independent review, that its processes meet established standards and when a certificate holder is required to periodically demonstrate command of a body of knowledge that is essential to current professional practice.
  
  
  OBJECTIVE
  We report herein a current Standard of Knowledge in general toxicology compiled from the experience and opinions of 889 certified practicing professional toxicologists.
  
  
  CONCLUSIONS
  An examination is the most commonly used instrument for testing a certification candidate's command of the body of knowledge. However, an examination-based certification is only creditable when the body of knowledge, to which a certification examination tests, is representative of the current knowledge, skills, and capabilities needed to effectively practice at the professional level. Thus, that body of knowledge must be the current "Standard of Knowledge" for the profession, compiled in a transparent fashion from current practitioners of the profession.
  
  
  CONCLUSIONS
  This work was conducted toward ensuring the scientific integrity of the products produced by professional toxicologists.
