I believe that is because each state have different quailifications for CNA's.
Just curious, if you knew you were moving, why didn't you check it out before hand?
BTW what school are you going to?
My biggest pet peeve with illinois, was I went to school in Indiana, took the NCLEX in Illinois and they wanted a copy of my DD214 (military discharge). I lost my copy in the move, and the military lost the originals in the St. Louis Fire). Then Illinois was trying to deny me access for the test. It some how got resolved by the grace of God.
