The Plant Operator Selection System (POSS) test is an exam designed by the Edison Energy Institute (EEI) to assess your aptitude and skills with relation to power plant operations positions, such as those in fossil, hydroelectric, or nuclear power plants. The POSS is administered by a variety of utility companies to ensure their potential employees have the requisite knowledge and skills to be productive, efficient power plant employees. Many companies administer the POSS as part of the application process, which means the specific regulations and conditions for the exam may vary. Your future employer will provide you with additional information regarding their POSS testing process.
