The online version of the Nebraska Wesleyan University catalog supersedes any printed catalog or PDF version as the official catalog of NWU. NWU reserves the right to make changes in the regulations and offerings announced in this official online version, as circumstances require. It is expected that the only changes will be the correction of errors and the inclusion of new courses and programs approved during the academic year.
