INTRODUCTION

This curriculum revision for the Level 2 – Tool and Die Maker – Tool/Tooling Maker for is based upon the on-the-job performance objectives, located in the industry- approved training standard.

The curriculum is organized into 12 reportable subjects. The Program Summary of Reportable Subjects chart summarizes the training hours for each reportable subject.

The curriculum identifies only the learning that takes place off-the-job. The in-school program focuses primarily on the theoretical knowledge and the essential skills required to support the performance objectives of the Apprenticeship Training Standards. Employers/Sponsors are expected to extend the apprentice’s knowledge and skills through practical training on the work site. Regular evaluations of the apprentice’s knowledge and skills are conducted throughout training to ensure that all apprentices have achieved the learning outcomes identified in the curriculum standard.

It is not the intent of the in-school curriculum to perfect on-the-job skills. The practical portion of the in-school program is used to reinforce theoretical knowledge. Skill training is provided on the job.
