The primary purposes of the American Board of Neurological Surgery are to conduct examinations of candidates who voluntarily seek certification, and to issue Certificates to those who meet the requirements of the Board and satisfactorily complete its examinations. Certification by the ABNS is based on review and evaluation of the applicant’s educational, training, and practice qualifications, as well as successful completion of written and oral examinations. In addition, the Board, along with the Residency Review Committee for Neurological Surgery (RRC) and the Accreditation Council for Graduate Medical Education (ACGME), works to improving the standards of training in neurosurgical residency programs throughout the United States.  http://www.abns.org
