A number of laboratory metrology seminars are offered by the NIST Office of Weights and Measures (OWM) Laboratory Metrology Program. Course descriptions, the current schedule, and the link to sign up for seminars are provided here. The duration of all webinars is two hours. The duration of all courses, with the exception of the Mass Metrology and Advanced Mass Seminars, is one week. The Advanced Mass Seminar is nine days, and the Mass Metrology Seminar is two weeks.

All courses will meet at NIST at the following location unless otherwise indicated on your confirmation notice:

National Institute of Standards and Technology (NIST)
Building 101, Room B 11
Gaithersburg, MD 20899

Sign-up and Confirmation

Log into the OWM database to request training using the OWM Contact Management System. Telephone requests and emails to sign up for a class are not accepted. Once we have your request to participate in the system, you will get a "registration" email. This is NOT a confirmation for the class. We will send an official confirmation letter approximately six to eight weeks before the seminar (when possible) with detailed information about payments, with the schedule and location of the seminar. Webinar confirmations may be sent by email closer to the event unless there are payments required.


The Washington Metrorail (light rail system) is available from National Airport (awkward with much luggage). You must purchase a ticket at the National Airport Metro station for the entire trip. Take the Blue Line from the airport, change to the Red Line at Metro Center station and take the Red Line to the last stop at Shady Grove, then take a cab to the hotel. Taxis are also available at a cost between $40 and $50. You may also rent a car if you so desire. Many of the local hotels have a shuttle to and from NIST. Please verify if your hotel has shuttle service to NIST when making room reservations.

Security Instructions

You will need a government-issued photo ID (e.g., passport or driver's license) when you check into the Visitors Center at the entrance of NIST on Monday morning. If you will be driving, please bring your Vehicle Registration card also.
PLEASE NOTE: Effective July 21, 2014, under the REAL ID Act of 2005 ( (link is external)), agencies, including NIST, can only accept a state-issued driver's license or identification card for access to federal facilities if issued by states that are REAL ID compliant or have an extension. NIST currently accepts other forms of federally issued identification in lieu of a state-issued driver's license, such as a valid passport, passport card, DOD's Common Access Card (CAC), Veterans ID, Federal Agency HSPD-12 IDs, Military Dependents ID, Transportation Workers Identification Credential (TWIC), and TSA Trusted Traveler ID.
