This work process schedule is attached to and a part of the Apprenticeship Standards for the above identified occupation. This sequence of Related Classroom Instruction is competency based and will be offered as traditional classroom training or independent study, which may include electronic media.

1.  TERM OF APPRENTICESHIP
The term of the occupation shall be four (4) years with an OJL attainment of 8000 hours supplemented by the required hours of related technical instruction.

2.  RATIO OF APPRENTICES TO JOURNEYWORKERS
One (1) Apprentice to one (1) Journeyworker: one apprentice for the first skilled
journeyworker employed, and one additional apprentice for each additional skilled
journeyworker employed thereafter.

3. APPRENTICE WAGE SCHEDULE AND FRINGE BENEFITS
Apprentices shall be paid a progressively increasing schedule of wages and fringe benefits based on a percentage of the current journeyworker wage rate.

Term: 8000 Hours
1st 1000 hours = 50 percent of journeyworker’s rate and fringe benefit payments
2nd 1000 hours = 55 percent of journeyworker’s rate and fringe benefit payments
3rd 1000 hours = 60 percent of journeyworker’s rate and fringe benefit payments
4th 1000 hours = 70 percent of journeyworker’s rate and fringe benefit payments
5th 1000 hours = 75 percent of journeyworker’s rate and fringe benefit payments
6th 1000 hours = 80 percent of journeyworker’s rate and fringe benefit payments
7th 1000 hours = 85 percent of journeyworker’s rate and fringe benefit payments
8th 1000 hours = 90 percent of journeyworker’s rate and fringe benefit payments

4.  SCHEDULE OF WORK EXPERIENCE (See attached Work Process Schedule)
Apprenticeship Committees may add to the work processes prior to submitting these Standards to the appropriate Registration Agency for approval.
