Millwright Level 4

Millwright Level 4, 4th Edition, serves as the final installment of NCCER's four-level curriculum for a standard millwright apprenticeship program. Published by Pearson, this textbook provides step-by-step guidance on installing, removing, troubleshooting, and maintaining the components of mechanical systems.

Across fourteen modules, the curriculum addresses fundamental industrial equipment and operations. Instruction covers topics such as basic hydraulic systems, conveyors, belt and chain drives, and precision laser alignment.

Revised from five levels down to four, the 2024 edition matches a standard four-year training program while incorporating modern tools, updated practices, and an expanded emphasis on maintenance. More than 100 hours of elective modules are also available for extended training programs.
