Pre-Employment Testing

Pre-employment testing is a common requirement for energy companies. This means that for many energy industry jobs, especially those technical in nature, individuals must pass a written or computerized test in order to go through the entire employment qualification process with an energy employer. These batteries may include the following, which are the most common administered by utilities:

Plant Operator Selection System (POSS)
Power Plant Maintenance Selection System (MASS)
Construction and Skilled Trades Selection System (CAST)
Technician Occupations Selection System (TECH)
System Operator/Power Dispatching Positions Selection System (SO/PD II)

It is important to ensure you are ready and prepared for the pre-employment test since if you do not pass the appropriate pre-employment test, there is a waiting period to re-take the test.
