NOCTI teacher exams assess individuals' technical knowledge and skills in an online proctored proficiency examination format. These assessments are used in a large number of states as part of the teacher licensing/certification process as they assess competency in all aspects of a particular industry.
In the lower division baccalaureate/associate degree category, 1 semester hour in Introduction to Engineering Technology, Introduction to Manufacturing Engineering Technology, or Introduction to Precision Manufacturing Technology (5/12) (12/16 revalidation).
