Contracting officers must complete one of the Delegation of Procurement Authority (DPA) training options, but we highly recommend all members of the acquisition team attend a live DPA training session to have a more interactive training experience with our instructors. DPA participants may include:
Before issuing a task order on a GSA GWAC, warranted contracting officers must complete one of the listed options below and request procurement authority from GSA.
*We highly recommend customers attend a live webinar for a specific GWAC or attend a combined session if you want a DPA for two or more of GSA's GWACs. Webinars last approximately one to two hours, and many sessions offer Continuous Learning Points.
If you have questions regarding GWAC DPA training, please reach out to alliant2@gsa.gov (Alliant 2) or sbgwac@gsa.gov (8(a) STARS III and VETS 2).
