The National Stone, Sand and Gravel Association is the leading voice and advocate for the aggregates industry. We advance public policies that protect and expand the safe, environmentally responsible use of aggregates that build America's infrastructure and economy.

NSSGA is the leading voice and advocate for the aggregates industry. Our members - stone, sand and gravel producers and the equipment manufacturers and service providers who support them - are responsible for the essential raw materials found in every home, building, road, bridge and public works project and represent more than 90 percent of the crushed stone and 70 percent of the sand and gravel produced annually in the United States. U.S. domestic production and use of construction aggregates amounted to 2.5 billion tons of crushed stone, sand and gravel-valued at $25.1 billion.

In-person courses provide intensive, hands-on education and training that's geared exclusively to the aggregates industry. Learn from expert trainers and share ideas with classmates from other companies facing the same challenges you see in your everyday business. You'll return to your operation with new perspectives and skills you can apply to your job immediately. Most of NSSGA's workshops and seminars are held in conjunction with the AGG1 Academy & Expo and NSSGA's Annual Convention.
