A federal government job can be quite alluring to most people looking for employment. Many government jobs offer good pay and benefits. That may explain why so many people turned over about $900 in Greenville this week to take a course offered by the State National Training Service career development program out of New Jersey. The program's representative, Perry O'Hannon, says his company helps train individuals for federal government exams. But we found similar training materials to learn how to take the government exams are available at public libraries for free. The U.S. Office of Personnel Management is investigating the State National Training Service.
