Sign-up and Confirmation

Log into the WMD database at to request training. 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.
