Final answer:
E4 and below OCCSTDS not covered in 'A' school are taught through fleet training, advanced technical education, and professional military education, as well as non-formal methods like self-study and online resources.
Step-by-step explanation:
The student is asking about where the remaining E4 and below Occupational Standards (OCCSTDS) that are not selected to be taught in 'A' school should be taught. In the military, specifically the US Navy, if these Occupational Standards are not covered in 'A' school, they are typically taught through on-the-job training (OJT), also known as fleet training. This on-the-job training occurs within the respective sailor's assigned command or unit where experienced personnel instruct and mentor junior sailors.
Another method is through advanced technical education at 'C' schools or through specialized courses designed for specific skills or equipment. Non-formal methods such as self-study, correspondence courses, or online resources provided by the military could also be utilized for this purpose. Additionally, leadership development is a critical component and is often addressed through professional military education (PME).
