This study analyzes the various Navy Nurse Corps (NC) accession sources for associated costs and retention rates for cohorts accessed between FY00 and FY13. Individual NC accessions data were obtained from the Bureau of Medicine Information System. A logistical regression model was used to analyze six- and 11-year retention rates. The findings indicate that accessing through the Medical Enlisted Commissioning Program and the Seaman to Admiral-21 (STA-21) have higher rates of retention at six and 11 years while the Naval Reserve Officer Training Corps (NROTC) and the Nurse Candidate Program accessions had a lower overall likelihood of retention. The study finds that the most expensive accession source is the STA-21 program with a total cost of $196,744. Further findings show the least expensive accession source is Direct Procurement with a total cost of $25,000 per accession. However, the STA-21 program had the highest retention rate at six years at 91.23 percent. The NROTC program had the lowest retention rate at six years at 54.62 percent. The data analyzed in this research suggests that Bureau of Medicine should reconsider the NROTC NC program option due to high attrition.
