The Workforce Training Series was developed to assist current new-and mid-level employees of gear manufacturers. The series provides a comprehensive overview of gearing to enhance students’ understanding of essential terminology and practices within the industry. Students go through a self-paced training course followed by a test for each course. Study guides and related materials, including practice tests, are provided for optimal success.

This series of courses has been developed using AGMA Standards. The material references AGMA Information sheet 915-1-A02 and ANSI/AGMA technical standards 2015-1-A01 and 2015-2-A06.
