If your goal—either currently or in the future—is to obtain a journey-level license, you will first need to participate in an approved apprenticeship. There are two critically important requirements of the apprenticeship agreement that you should be aware of, to prevent difficulties in achieving your license. 

First, the apprenticeship agreement consists of Related Technical Instruction (RTI) and On-the-Job Training (OJT). Most apprenticeships require at least 2000 total hours of OJT and at least 600 total hours of RTI.  

CSM provides RTI; each semester-long course provides 75 hours of RTI. For example, Electricity I, Part 1 is 75 hours, and Electricity I, Part 2 is 75 hours. You’ll receive 150 hours of RTI for successfully completing these two courses. CSM courses do not fulfill the On-the-Job Training requirement of your apprenticeship. 

Second, your apprenticeship must have a sponsor, and your sponsor must be approved by the Maryland Apprenticeship and Training Council before you can begin your apprenticeship. MATC is a division of Maryland’s Department of Labor. This requirement is essential to ensure that your OJT hours are documented properly.  

You may choose an existing, registered apprenticeship program, such as ABC-Chesapeake Shores (ABC) or Independent Electrical Contractors (IEC); CSM has working relationships with both of these apprenticeship programs.  

As an alternative, you can potentially complete your apprenticeship with your employer as your sponsor. However, your employer cannot sponsor your apprenticeship until it submits the required paperwork to register as a Maryland Apprenticeship Training Program (MATP) and is recognized as an approved Apprenticeship Sponsor. 

Do not begin working for this employer until your employer has been approved by MATC.

Employers may contact the Office of Apprenticeship: info@mdapprenticeship.com

If you would like to begin an apprenticeship with a program or employer, but you aren’t sure if that sponsor is registered and approved, contact MATP at info@mdapprenticeship.com to verify their status before beginning an apprenticeship with them.
