Greater Lawrence Technical School is offering professional electrical and plumbing apprenticeship courses this fall, preparing trainees to take journeyman trade exams.

Superintendent John Lavoie said classes are open to Greater Lawrence Technical School graduates and area apprentices, but warned space is limited.

“These classes are a great way to develop the knowledge necessary for proficiency in these trades, and for students to grow and advance in their careers,” he said.

The Greater Lawrence Technical Institute electrical program will offer 600 hours of theory. The program consists of four courses, each with two semesters of 75 hours. Classwork is based on the National Electrical Code and Massachusetts Electrical Code. Successful graduates will leave prepared to take the journeyman electrician exam administered by the Massachusetts Electricians Board.

The plumbing program will offer 550 hours of theory. The program consists of five courses, each with two semesters of 55 hours. Under Massachusetts law, students must hold a current Massachusetts Apprentice Plumber’s license to apply course hours toward their educational requirements. Successful graduates will leave prepared to take the Massachusetts Journeyman Plumbers exam.

Courses must be taken in sequence. Students must show proof of completing the previous class level. Classes are held from 5:30-7:30 p.m., either Mondays and Wednesdays or Tuesdays and Thursdays. Courses begin in early September, and end in the spring, and cost $1,100 for the year for each level of electrical training and $900 for the year for each tier of plumbing training. Registration is online only.
