Credit Recommendations

The American Council on Education recommends that semester hour credits be awarded in the vocational certificate and lower-division bachelor's/associate's degree categories for courses taken in this rating on electricity and electronics.

Qualifications and Interests

The most important qualifications for the EM rating are manual dexterity; competence with tools, equipment and machines; ability to do detailed work; a logical mind; resourcefulness; and a willingness to learn about electricity, electrical systems and test equipment. Normal color perception is required.

Working Environment

Most work in the EM rating is performed indoors, under varied conditions at sea and ashore. Work may be done in a shop-like environment. EM’s do mostly physical work of a technical nature and usually work closely with other ratings. EM’s are stationed primarily aboard USN ships.
