Five (5) year apprenticeship
Apprenticeship in the pipe trades is extremely selective. Acceptance for training depends on the applicant’s qualifications and the manpower need of the trade. In order to increase your chances of being admitted for our program, we highly recommend that you attend a Registered Pre-Apprenticeship program that utilizes the Multi-Craft Core Curriculum.

The typical apprenticeship program is five- years of intensive technical training, consisting of at least 10,000 hours of on-the- job and related classroom training.

Processes related to mathematics, drafting, the use of tools and maintenance, general shop and work practices, including safety, restressed during the apprenticeship both on-the-job and in the classroom. Week-long, daytime classes are attended six times per year.

During that week of school, apprentices receive State of Iowa Training monies. At the conclusion of an apprenticeship, one will not only have six licenses but an Associate in General Studies (AGS) degree.

Apprentices earn all of this for the small cost of books. In 2016, this was $200.00 per year!


An apprentice’s starting wage is 45% of journeyworker wages, with incremental increases throughout the apprenticeship. Apprentices also receive benefits which include health insurance and pension.


Applications are accepted on a continuing basis. There is a $25 application fee. Interviews are given every three to four months.
