About Granite State Trade School

In 2002, we recognized a need for training in natural and propane gas, as well as appliance installation and service. At the time, no training of this type was available in New Hampshire. After course planning and development, Granite State Trade School welcomed its first group of students in 2006.

Granite State Trade School which was originally created to train contractors in the gas industry. With New Hampshire preparing to require gas licensing, Granite State Trade School was fully prepared to meet the needs of New Hampshire’s workforce with a comprehensive training program. As a result, GSTS was the first independent program approved by the office of the State Fire Marshall as an approved training provider and testing proctor for the State’s gas licensing program.

Since its inception, Granite State Trade School has grown and expanded its course offerings. Today the school provides expert training for gas licensing, continuing education courses in Gas and Plumbing, HVAC Technician, Oil Burner Technician, and an a full four-year apprentice program in plumbing. The school continues to be recognized as a provider of quality trade education thanks to our expert instructors and state-of-the-art facility.
