Marshal, as in Deputy U.S. Marshal has only one "L"...
Believe me, some Deputies will make a big deal of this...
For the record, the USMS has a huge backlog of personnel that took the test last year, and they will be working off that list for several years...maybe as many as 3-4 years..so if you did not test last year there are only two other ways to get on in the near future...
Once a year or so, the USMS allows status candidates, or admin, secretarial types, to apply for a DUSM position without taking the test....this is one way, to become an admin employee, and then apply from the inside.
Another, is if they offer a special program again designed specifically for a particular group of hires ... i.e. "Operation Shining Star" in 1999, they only tested and interviewed separating military members..
Good luck..
