Red Seal certified welders may pursue an additional level of specialty training in low alloy and stainless steel welding. This is an optional five-week program which requires the welder to register as an apprentice with an employer sponsor. Upon successful completion of technical training, an ITA standardized exam and 900 work-based hours, a "Specialty Metals Endorsement" will be affixed to the welder's existing Certificate of Qualification. All apprentices who complete the Optional Level: Specialty Metals Endorsement of the Welder program with a final level percentage score of 70% or greater will write the ITA examination as their final assessment. A minimum percentage score of 70% on the examination is required for a pass.
