The North American Substance Abuse Program (NASAP) utilizes third-party administrators ( TPAs ) to manage the program for participating contractor clients.  Administration includes: notification of required tests, specimen collections and testing, database management, medical reviews, referrals to substance abuse professionals for rehabilitation, and maintaining status information for employees.  Additionally, TPAs train appropriate contractor employees that will be involved in administering the NASAP.

TPAs submit events related to substance abuse testing to the NASAP database where status will be determined. TPAs also coordinate with other TPAs as employees transfer to other employers.

Four TPAs have been selected to administer the NASAP.
