Students work in various local machine shops under the supervision of an approved employer. Students must have a 3.0 GPA or better in current coursework, must not be under any type of probationary contract, and must complete and submit a regular work experience employer evaluation. The instructor or administration may terminate the externship at any time if the student does not adhere to the requirements stated in the externship training packet. If a student does not obtain an externship, completion of a machine capstone project will be required.
