There are very few qualifications needed to get a job in general construction. Although having a high school diploma or GED certificate is useful, it is not typically a prerequisite for being a construction laborer. To be a craft worker helper, you do need a high school diploma. If you are interested in a more formal route, the Laborers’ International Union of North America sponsors an apprenticeship program, which provides a mix of on-the-job training and classroom instruction where you learn the skills necessary to complete your duties, such as how to follow building code requirements.
