Employment Potential

A graduate of this program will have the potential for employment in the following areas:

Detailer: produces detailed drawings of parts of machines from supplied information on CAD, and make drawing changes to comply with Engineering Change Notices (ECN’s)/ Engineering Change Requests (ECR’s).

Mechanical Design Technician: applies knowledge of mechanical engineering technology to design, develop, and test new or revised machinery; assists in component selection and sizing of machine members; has duties split between design and drafting and may specialize in a specific type of machine or product. Most work is performed on a computer.

Requirements for Program Entry

. Completed application.
. High school transcript or equivalent. (For a list of equivalents, go to www.nwtc.edu/gettingstarted.)
. As a requirement for program entry, an Academic Skills Assessment (Accuplacer) with appropriate benchmark scores is necessary. Program Benchmarks are: Reading Comprehension: 55; Arithmetic: 34; Sentence Skills: 60. However, we recommend a student receive the following scores to be successful in this program. Reading Comprehension: 75; Arithmetic: 96; Sentence Skills: 84 Remediation options are available to reach recommended scores. Equivalent assessment scores are acceptable. To learn more about these assessments and program benchmark scores, please contact a Counselor (920) 498-5444 or (888) 385-6982.
