8 12 Total Level I
8 4 Total Level II
high school graduate or equivalent A*
completion with passing grades of at least two years of engineering or science study at a university, college or technical school B*
this is a progressive training course; i.e., consideration as level I is based on satisfactory completion of the level I training course; consideration as level II is based on satisfactory completion of both level I and II training courses. Topics in the training outline may be deleted or expanded to meet the employer's specific applications or for limited certification and may be accompanied by a corresponding change in training hours. Recommended hours of instruction should be considered as a minimum requirement, regardless of training course topic changes.
