Use of NICET certification varies according to needs determined by employers, specifiers, and local government. Specific certification requirements established throughout the United States vary by engineering technology fields in various states and localities. Some areas may require a NICET or similar certification as condition for employment. Often an engineering technology degree is used in lieu of a technician certification in areas where they deem a four year engineering technology degree to have more value than a technician certification earned through work history and testing requirements.
