A - Yes.  However, testing in prisons requires making special arrangements, usually through an attorney, to insure that an adequate room is provided which is free from interfering noises and distractions.  You should also discuss test duration with the examiner so that sufficient time is allotted for the test.  The exam fee may be somewhat higher than listed, particularly if the examiner's office is not nearby, due to the extra time required for travel and passing through security procedures at the facility.
