These resources are designed to help quarry managers train employees on safety best practices and can be administered in a group setting or one-on-one with new hires.

Sustainability Standard: The Natural Stone Sustainability Standard (ANSI/NSC 373) is a certification program that creates a way for quarriers to prove their commitment to sustainable practices to the design community and potential customers.

The Natural Stone Institute’s CEU program consists of multiple turnkey presentations, as well as sessions that can be customized to your company. All CEU speakers have access to full administrative support from Natural Stone Institute staff.

Natural Stone Promotion: The Natural Stone Institute works to help create demand and desire for natural stone through promotion and education. Quarries are featured in articles on Use Natural Stone (, which aims to educate and inspire consumers, designers, and architects to choose genuine natural stone. Member quarries are also the subject of quarry tours each year, both virtually and in person through a webinar series and annual study tour opportunities that are promoted both to the stone industry and design community.

Resources for Salespeople: Utilize the resources in the Natural Stone University to train salespeople and other employees.
