Minimum Qualifications for credentialed nurses within the specialty areas (i.e. ED, ICU, OB, etc). Nurses who are not credentialed may apply with the commitment, if offered block, to move towards becoming credentialed. A plan would be made for the applicant to complete all necessary training within 12 weeks. If an extension beyond 12 weeks is needed, meetings at 12 weeks and 6 months with the nursing manager will occur to ensure progress towards credentialing.
