Many masons first gain experience as construction laborers. They begin with tasks such as edging and jointing and using a straightedge on freshly placed concrete. As they progress, assignments become more complex, and trainees usually can do finishing work within a short time. A written test and a physical exam may be required. In the classroom, apprentices learn applied mathematics, plan reading, and safety.
Apprentices generally receive special instruction in layout work and cost estimating.
When hiring helpers and apprentices, employers prefer high school graduates who are at least 18 years old, in good physical condition, and licensed to drive. The ability to get along with others also is important because concrete masons frequently work in teams. High school courses in shop mathematics and blueprint reading or mechanical drawing provide a helpful background. Experienced concrete masons or terrazzo workers may advance to supervisors or contract estimators. Some open their own concrete contracting businesses.
