According to Azuka Kagami, his official court rank when he passed away was Jugoinoge, Shimotsuke no kami, however, his job rank described in the same book was 'Saemon no jo' or 'hangan', whose court rank was Jurokui or Jushichii, so that his official court rank Jugoinoge, Shimotsuke no kami might be wrong.
吾妻鏡には卒去時の官位として下野守従五位下とあるが、同書に見られる朝政の晩年の職位は「左衛門尉」や「判官」であり、これらは従六位か従七位の官位であることから、従五位下下野守は誤りの可能性が高い。
