Please Note: Apprenticeship Training and Curriculum Standards were developed by the Ministry of Training, Colleges and Universities (MTCU). As of April 8th, 2013, the Ontario College of Trades (College) has become responsible for the development and maintenance of these standards. The College is carrying over existing standards without any changes. However, because the Apprenticeship Training and Curriculum Standards documents were developed under either the Trades Qualification and Apprenticeship Act (TQAA) or the Apprenticeship and Certification Act, 1998 (ACA), the definitions contained in these documents may no longer be accurate and may not be reflective of the Ontario College of Trades and Apprenticeship Act, 2009 (OCTAA) as the new trades legislation in the province. The College will update these definitions in the future. Meanwhile, please refer to the College’s website (http://www.collegeoftrades.ca) for the most accurate and up-to-date information about the College. For information on OCTAA and its regulations, please visit: http://www.collegeoftrades.ca/about/legislation-and-regulations

PREFACE The Metal Fabricator curriculum has been developed in keeping with the Format Guidelines prescribed by the Ministry of Training Colleges and Universities (MTCU) from the trade workplace training standards. This curriculum reflects the content necessary for an appropriate progression through Level II. For easy reference, a time allocation has been included for each respective reportable subject and units, along with a breakdown of theory and application in the delivery of the performance objectives. The continual introduction of innovative technical advances is resulting in increasing demand for tradespersons who are not only skilled in the practical aspects, but who also have a sound theoretical knowledge of the trade. The curriculum has been designed to give the instructor every opportunity for flexibility and innovation without significant departures from content. Since the scope of the prescribed curriculum is quite extensive, the apprentices will be expected to reinforce the acquired knowledge through regular independent out-of-classroom assignments. The curriculum includes specific references to the apprenticeship training standards. While terminal performance objectives in the training standards have been linked to the respective in-school learning outcomes and learning content objectives, employers should not assume complete coverage in all aspects of the objectives. The in-school delivery focuses primarily on the knowledge required and fundamental skills that support the respective performance objectives outlined in the training standards. Employers are expected to complete the delivery of these objectives by applying the prescribed in-school knowledge to the practical learning experiences in the work setting. The reportable subject titles and learning outcomes described in Level II may be duplicated in Level III, but they increase in complexity or describe a more advanced technique as they move from Level II through Level III. Therefore, the repetition does not indicate a need to re-teach the previous level, but to build upon previous learning. Regular evaluations of an apprentice’s learning achievements must be performed in both theory and practical applications throughout the program.
