Some of the positions at Exelon require evaluation tests. For testing purposes, Exelon collaborates with Edison Electric Institute (EEI), the association that represents all US investor owned electric companies and developed the materials and formats of the tests. If you are applying for an executive position you may be required to take the Hogan assessment test (HPI and HDS).


There Are Several EEI Tests

If you are selected for a position that requires EEI testing, you must know that there are several EEI tests. Each test is designed to assess a particular set of skills required for a certain position. The EEI tests conducted at Exelon are:

  • POSS test: for plant operating positions
  • MASS test: for plant maintenance positions
  • CAST test: for professional positions
  • TECH test: for technical positions
  • SASS test: for administrative positions;
  • SO/PD test: for system operating and power dispatching positions
  • MRAB test: for meter reading positions
  • CSR test: for customer service positions

Hogan Assessment Tests  

In addition to asking job applicants to take the EEI tests, Exelon also requires them to pass the Hogan Personality Assessment. Passing the Hogan tests is particularly important for those job candidates who are competing for management positions. There are two Hogan tests that are usually included in Exelon’s pre-employment assessment—the Hogan Personality Inventory (HPI), and the Hogan Development Survey (HDS).

The Hogan Personality Inventory (HPI)

The Hogan Personality Inventory analyzes human traits that help people build meaningful and productive connections with each other. High scores in this test assure employers that job applicants will get along well with their co-workers. The HPI is comprised of seven primary and six occupational scales. It also has as many as 42 sub-scales. The test's completion time usually ranges from 15 to 20 minutes.

The Hogan Development Survey (HDS)

The Hogan Development Survey assesses negative human traits that prevent workers from succeeding at their jobs. Employers at Exelon use this test to minimize the occurrence of counterproductive situations at workplaces. The HDS includes 11 personality scales that are further subdivided into 33 sub-scales. It contains 168 true or false questions and should be completed within 15-20 minutes.

The relatively short time limit allowed for the completion of the Hogan tests makes them challenging. To pass them successfully within a given time limit, do several practice exercises and drills with our exclusive PrepPack™.
