The National Institute for Metalworking Skills is highlighting its National Standards for Metalworking training and the program’s benefits for in-house training programs. The institute works with industry to set skills standards and establish national-level credentials to certify trainees in machining, metalforming, stamping, screw machining and machine maintenance. To earn credentials, which start at entry-level skills, but expand to any level, trainees make parts and then take online theory tests.
