Below is a nice, high-level overview CGO published on the service selection process: On May 22, 2009 the Class of 2009 graduated and earned their commissions in either the Navy or Marine Corps. Following their basket leave they will report to various positions around the Yard, Flight School, a first ship, Nuclear Power School, etc. The service selection process began in the first semester of their First Class year. Each midshipman selected their top five preferences for service selection. The process continues in different ways depending on the specific warfare community. Most include formal interviews and a selection board. The midshipmen are notified in the end of January of their service selection. Some communities are more competitive than others but approximately 90% of First Class midshipmen will receive their first choice. The number of billets available in each community is based on the needs of the Navy and Marine Corps. In addition, starting with the Class of 2010 up to 25 graduates may be commissioned in the Medical/Dental Corps. Following service selection each midshipman chooses their first ship, flight school date or other school date. This selection is done based on Overall Order of Merit (combination of academic class rank and military performance). Each midshipmen will then attend one credit practicum class during the final semester to help prepare them for warfare community. Pilots will get a head start on flight school, Surface Warfare Officers will receive advanced navigation training and so on.
