The Missouri State Board of Nursing, as far as research could tell, asks nothing of a school from elsewhere before its students train in Missouri: no approval, no notice. Its program rules, 20 CSR 2200-2, speak to programs the Board itself recognizes. RSMo 335.081(6)(a) lets students of approved nursing schools practice under supervision without a license, and leaves open where out-of-state schools stand.
AANP counts Missouri as restricted. An NP there never outgrows the collaborative practice arrangement with a physician, and the arrangement brings ratio limits, chart-review duties and prescribing limits for controlled substances. Missouri's community preceptor tax credit, RSMo 135.690, rewards physicians and PAs who teach Missouri medical and PA students; NPs and nursing students are not part of it. Large systems include CoxHealth, SSM Health, BJC HealthCare, MU Health Care and Mercy, around St. Louis, Kansas City, Springfield and Columbia.
