If you do not have enough rated time to provide 4 years of evaluations, you must provide what you have, to include any DA 1059s (AERs) you received from any NCOES you have attended. An absolute minimum of 18 months as an NCO is required for reclassification consideration. Your current senior rater in a memorandum for record must address any gaps in rated time, to include time between the last NCOER/AER and the Accession Panel Date.
