Employment Tests

Employment tests are an important tool used by Orlando Utilities Commission in the selection of qualified individuals for jobs. Some of the tests we administer were developed through the Edison Electric Institute (EEI), an association of electric companies created over 70 years ago to exchange information on industry developments and to act as an advocate for utilities on subjects of national interest. EEI acts as an information exchange for its over 200 member companies and a public relations voice for the electric energy industry as a whole.

The EEI provides the following link for your use to learn more about the tests, take practice tests, and improve your skills. http://www2.eei.org/eeitests/onlineproducts/Login.aspx. When the login screen appears, use "reliable1" for User Name and "ouc" for Password.
