The Ready Relevant Learning pillar of Sailor 2025 is a transformational Navy initiative intended to accelerate the learning of Sailors for faster response to rapidly changing warfighting requirements. One goal of Ready Relevant Learning is to ensure every Sailor receives modernized training closer to the point of need to support assigned tasking. Currently, accession Sailors’ training is front-loaded with a large amount of content delivered after basic training and before their first deployment. Modernization efforts focus on distributing training out of the schoolhouse to the waterfront and operational environment, utilizing modernized delivery systems to simplify Sailors’ access to training. The Ready Relevant Learning training paradigm supports a Sailor’s career progression by providing training tailored to initial job demands and continuing skills development for subsequent tours and career milestones. The Ready Relevant Learning content modernization effort includes the following analysis activities: Rating Domain Analysis and Media and Fidelity Analysis. Rating Domain Analysis and Media and Fidelity Analysis use consistent, repeatable processes and feed into the Functional Requirements Document to produce recommendations on content modernization and training timing. While all the activities work together, this paper will focus solely on the Rating Domain Analysis. The Rating Domain Analysis is a novel analysis methodology to answer the question of when exactly training should be provided. It involves identifying the work a Sailor performs in the Fleet and aligning existing learning objectives with those discrete tasks. This Rating Domain Analysis also identifies potential gaps in training, where work is performed on the job but no training content exists in support of that work, as well as areas of overtraining, where training content is being delivered that does not support work Sailors perform on the job. The paper will discuss the Rating Domain Analysis process, development and why the Rating Domain Analysis is a powerful tool to improve Navy training.
