For as long as there has been a stained glass field in America, its best practitioners have faced a choice: protect what they know, or share it. Accredited Professional Membership in the SGAA is built on studios that chose to share it.

The stained glass tradition is deep and global. But America built differently, and American preservation is a different challenge. Accredited studios are part of an active, ongoing conversation about what best practice actually means here, now, for the work in front of us.

What Accreditation Means

Accreditation is not a seal handed out to those willing to pay for it. It is a peer-reviewed credential earned through portfolio review, documentation of professional practice, and a panel interview with your colleagues and mentors in the field.

When clients, architects, preservation consultants, and institutional partners see the SGAA Accredited seal, they are seeing the endorsement of a community, not just an association. They are seeing studios that have agreed to be accountable, not just to a standard written on paper, but to the people working alongside them in this field.

The Application Process

Accreditation is substantial, and it is meant to be. Studios that complete this process come out of it stronger than when they started, with documentation and systems that serve their practice long after the application is done.

Step 1: Confirm Eligibility You must be a Professional Member in good standing for at least two years. If you are not yet a Professional Member, that is your starting point.

Step 2: Prepare Your Documentation The application asks you to compile:

  • Business documentation (license, ownership verification)
  • Current certificate of liability insurance
  • Studio safety policy or statement
  • Resume/CV and key employee summaries
  • Sample studio contract
  • Sample RFP/RFQ or proposal response in your classification
  • Seven letters of recommendation (five from clients, two from current Accredited Professional Members)
  • Portfolio of recent work (up to 20 pages, five project samples from the last three years)

Step 3: Submit Your Application Send your completed application, all documentation, and your $300 application fee to membership@stainedglass.org. Use the subject line: Accredited Membership Application – [Your Name / Studio Name]

Step 4: Committee Review The Membership Credentials Committee, made up of your peers and mentors in the field, will review your complete file. Review may take up to six weeks. If materials are missing, you will have 30 days to gather them.

Step 5: Panel Interview If your application is complete and meets requirements, you will be contacted to schedule a panel interview. Interviews are conducted at an SGAA conference or via Zoom. You will be asked to discuss your portfolio, your knowledge of SGAA best practices in health, safety, design, and installation, and your philosophy and approach to work in your classification.

Step 6: Accreditation Upon approval by the committee, you receive your Accredited Professional designation, the SGAA Accredited seal, and your place in a community of studios committed to raising the standard of this field together.

A Note on This Process

We understand this is a substantial application. Not every studio will have every document in a polished, ready-to-submit format, and that is fine. We are looking for professionalism and a willingness to engage in the process, not perfection. If you do not have a particular document, make a note explaining what you have in place or are working toward.

Some studios complete this process in weeks. Others take months, and that is not a failure. The committee reviewing your application is made up of your peers and your mentors. If the application reveals areas where your practice could grow, that is not a disqualification. It is the beginning of a professional relationship.

Why Accreditation Matters for the Field

The stained glass studios that have earned Accreditation are not just excellent in their craft. They are the studios willing to put their work in front of their peers and say: hold us to this. They are the studios that, when a significant preservation project comes through, a client or architect can trust to do the job at the level the work deserves.

There is extraordinary knowledge embedded in this field, passed through generations, documented in archives, and held in the hands of working practitioners. Accreditation is how the SGAA makes sure that knowledge is shared, challenged, tested, and carried forward, not hoarded.
