During its first three years of operation, 400 students attended classes in North Adams. Inflationary increases in travel costs, difficulties in travel and housing accommodations, and inclement winter weather, began to take their toll on enrollment. At the same time, there was a strong appeal to the school to provide classes closer to the homes of potential students.
Responding to those appeals, regional classes began in January of 1981. By establishing a program of courses offered in more than one location, it was hoped that revenue could be raised to help diminish the escalating operating expenses at North Adams. A few such classes had in fact already been tried, successfully, with the energetic cooperation of Elizabeth Perry (WA), Don Sharp (TX), Penny Starr (CA), Rick Hoover (MO), Dennis Harmon (TN), Chetty Mastroianni (TN) and Thurmon Radford (VA).
Another major project of the Stained Glass School was to expand the available written material available to those seeking professional knowledge of the craft. Together with the SGAA, the Stained Glass School produced the first edition of the Reference and Technical Manual under the guidance of Florence Welborn and her brother, William Davisson in 1988. Today, many chapters of the Resource and Technical manual are available on demand through Amazon Publishing, and the entire reference guide is under review for production of the 3rd edition.
Under the current leadership of Sr. Ann Therese Kelly, the School is seeing renewed interest in professional regional classes in both new and restoration techniques and design. Class offerings at annual conferences have been expanded to meet the growing demand and institutions and studios around the country are partnering with the Stained Glass School to revitalize the certification process for teachers and individuals.
