Our Curriculum
Apprentices may enroll in the program at any time throughout the year. The academic year runs from August to May. Apprentices who enroll after the start of the school year may begin gaining on-the-job training; however, curriculum credit will not commence until the following academic year. Enrollment initiates the application process, allowing apprentices to obtain their apprentice license and work under the supervision of a licensed journeyman.
Class credit is awarded in yearly increments of 144 hours. Partial credit is not granted if the full academic year is not completed. If a student does not fulfill the requirements for an entire year, no credit will be awarded for that period. In the event of re-enrollment, the student must retake the full year.
Students are permitted a maximum of four absences per year.
