Job Outlook

Significant Points

  • Two in three are employed in manufacturing establishments.
  • While a high school diploma is sufficient for basic testing of products, complex precision-inspecting positions are filled by experienced assemblers, machine operators, or mechanics who already have a thorough knowledge of the products and production processes.
  • Employment is expected to decline, reflecting the growth of automated inspection and the redistribution of quality-control responsibilities from inspectors to other production workers.
