Accreditation Management System
Welcome to The NELAC Institute's National Environmental
Laboratory Accreditation Management System

TNI LAMS is a central repository for information regarding the accreditation status of environmental laboratories.

TNI Accreditation Bodies are in the process of migrating accreditation data to this database. Currently it contains complete listings for LA, OR, MN, NH, NJ, TX, VA, UT, and partial for FL. Other ABs are expected soon.

To begin, click the Search button below. On the next page, you will be able to choose from a variety of ways to locate laboratories.


Please use the "contact" option at top-right to be directed to a form on which you can ask questions about database use, the data, or to offer suggestions for making the application more useful.

Disclaimer: All information obtained through TNI LAMS is accurate to the best of our knowledge. The quality and accuracy of the data is the responsibility of the appropriate Accreditation Body.
