The Accreditation Program raises the bar for quality in the stone industry and provides specifiers, contractors, and building owners with an easy to find collection of well-qualified stone professionals. It is the only independent third-party credentialing program for natural stone fabricators and installers; accrediting companies, not individuals.

Accredited companies are reviewed to ensure compliance with a rigorous set of metrics. 

  • Quality Control
  • Safety
  • Physical Facilities and Equipment
  • Business and Trade Practices
  • Technical Knowledge and Expertise
  • Customer Service
  • Ethics
  • Finance
  • Employment Practices and Training

 

There are three types of Natural Stone Institute Accreditation:

  • Accredited Commercial A Contractors specialize in heavy commercial projects including large-scale engineered high-rise cladding.
  • Accredited Commercial B Contractors specialize in general commercial projects including low rise cladding and interiors. Commercial A Contractors are also qualified for this work.
  • Accredited Fabricators specialize in countertops and other non-engineered residential or commercial interiors.
