Navy Readiness: Actions Needed to Evaluate the Effectiveness of Changes to Surface Warfare Officer Training, Report to Congressional Committees [open pdf - 7MB]
From the Highlights: "In 2017, the Navy had four mishaps at sea including two collisions that resulted in the loss of 17 sailors' lives and hundreds of millions of dollars in damage to Navy ships. In the wake of those mishaps, the Navy identified deficiencies in SWO [Surface Warfare Officer] ship-driving training and related experience as contributing factors and has undertaken a number of efforts to improve these areas. [...] GAO [Government Accountability Office] is making four recommendations to the Navy to routinely evaluate SWO training, including that the Navy collect and evaluate fleet-wide feedback on the quality of training; routinely conduct ship-driving competency assessments; provide standard criteria for qualifying ship drivers; and develop a plan to analyze and use logbook information. The Navy concurred with GAO's recommendations."
