Thus in September 1958 under a Flag Officer Sea Training, special "shakedown" or settling in courses lasting seven weeks were started to train the crews of newly commissioned ships in operating their equipment and give them experience in dealing with every eventuality likely to be met with in subsequent service at home and abroad."

BOST thus has elements of the US  Navy's Board of Inspection and Survey (INSURV) and Composite Training Unit Exercise assessments.
