Which of the following is NOT one of the four types of in-house training used in the Navy?

The correct choice identifies that "Technical" is not categorized as one of the four types of in-house training used in the Navy. The types of training recognized as in-house typically focus on areas that are essential for sailors in their roles and encompass Orientation, On-the-job training, and Professional development.

Orientation training is essential for new personnel to familiarize them with the Navy's culture, policies, and procedures. On-the-job training is a practical approach where sailors learn through direct experience while performing their duties under the guidance of more experienced colleagues. Professional development training is designed to enhance skills, knowledge, and leadership capabilities that support career progression.

While "Technical" training does occur in the Navy, it often refers to specialized skills involving machinery or technology, but it does not represent a standalone category of the established in-house training types. This clarification helps to understand the Navy's training framework more comprehensively.
