Apprenticeship
Curriculum Standard
Metal Fabricator
(Fitter)
Level 2
Trade Code: 437A
Date: 2011
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 outof-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.
