Step 1: Obtain Postsecondary Education

Although taking college courses or completing postsecondary education is not a requirement for becoming certified, employers may prefer to hire candidates with some vocational training. Certificate programs for aspiring mechanical inspectors can be found at community colleges and vocational schools. Coursework is designed to teach students skills in blueprint reading, calibration, inspection and testing, technical math and metrology.

Classes may also cover topics like applied technical mathematics, introduction to machine tools and mechanical inspection. Some training programs can also offer more specific courses that include inspection of bolting and fasteners, tubing and piping inspections, valve inspections and inspection results reporting.

Step 2: Gain Experience

According to ASQ, in order to be eligible for certification, candidates must have at least two years or experience in mechanical inspection or a similar field. This allows candidates to build a solid foundation for a career in mechanical inspection by gaining hands-on experience operating measuring machines, using calibration equipment, interpreting blueprints, planning inspections and evaluating quality. Employers also look for applicants with experience in related areas, such as inspection and mechanics.

Success Tip:

  • Begin preparing for the certification exam. ASQ offers online resources to help certification candidates prepare for the test, including online access to the Quality Inspector Body of Knowledge. ASQ also offers preparatory courses and links to books that can help prepare aspiring mechanical inspectors for the exam.

Step 3: Get Certified

The ASQ certification exam contains 100 multiple choice questions. Candidates are given four hours to complete the open-book test. Questions cover inspection and testing, metrology, technical math and quality assurance. The exam is designed to gauge knowledge and comprehension, as well as the ability to apply, analyze and synthesize ideas. The ASQ certification is a lifetime certification that does not require renewing. In addition to certification, the Bureau of Labor Statistics (BLS) suggests vocational industrial trades study to increase ones chances for opportunity and advancement.
