About the Course

Granite State Trade School (GSTS) partners with the Plumbing-Heating-Cooling Contractors Association (PHCC) to offer a hybrid e-learning Mentoring Program. Students enroll through GSTS and receive login credentials to access the PHCC online learning platform. In addition to completing online coursework, students attend three to four in-person mentoring sessions per year at our campus in Raymond, New Hampshire. These sessions provide classroom instruction, mentoring support, and assistance with technical or course-related questions.

GSTS is committed to offering high-quality training programs that support both e-learning requirements and traditional in-class instruction. Our programs deliver industry-leading training and exceptional value.

All apprentices enrolled in this hybrid program are required to attend scheduled mentoring sessions at Granite State Trade School. The final exam must be proctored in accordance with the Course Information guidelines. Course fees do not include textbooks; required textbooks may be purchased separately through GSTS or Cengage Learning.
