Our Curriculum
An apprentice may enroll in the program at any time during the year. The school year runs from August through May. If the apprentice enrolls after school is started they will be able to earn on the job training but their curriculum credit won’t start until the next school year. The enrollment allows for the application process to begin so that they can get their apprentice license and work under a licensed journeyman.
Credit for class is given in yearly increments of 144 hours. No partial credit is given if an entire year is not completed. If a student does not complete a year, no credit is given for that year and if re-enrolled the entire year would have to be taken over.
Two absences per semester for a total of four per year are allowed. There are no excused absences.
