The U.S. Navy is a highly complex organization. It
is complex not only because of its ships and
sophisticated equipment but also because of its Sailors
and their many occupational fields. As a Sailor and a
future petty officer, your leadership will help to keep our
Navy the greatest Navy in the world.
Nowhere in society today can you advance as fast
and as far as you can in the Navy. The opportunities for
you to have a successful naval career are limited only by
your abilities and efforts. This chapter is designed to get
you started on the path to a rewarding naval career. The
first section of this chapter deals with the Navy enlisted
classification structure. This system is covered because
it provides the framework for your career development.
The next sections contain information on duty
assignments to special programs and projects and the
enlisted warfare specialist program. The last section
provides information on enlisted service records.
You might be asking yourself, why do I need to
know this information? The answer is simplemany
Sailors know little about the administrative details that
affect their careers. The information contained in this
chapter is vital to a successful naval career. It deals with
the factors used, in part, to determine where you will be
assigned, when you will advance, and what special
programs you are qualified to enter.
If you have any questions, contact your leading
petty officer, division or department career
educational services officer (ESO). Because of
frequent changes to personnel policies by both the
Navy and the Department of Defense, some of the
information provided here may have changed by the
time you receive this manual.
THE NAVY ENLISTED CLASSIFICATION
Learning Objective: Recall the function and use of the
Navy Enlisted Classification (NEC) system.
The Navy Enlisted Occupational Classification
System (NEOCS) is presented in Basic Military
Requirements, NAVEDTRA 12018. NEOCS
consists of three major subsystems:
Enlisted rating structure
Navy Enlisted Classification (NEC) structure
In this chapter the NEC structure is discussed.
The NEC structure supplements the enlisted rating
structure. It identifies special knowledges and skills
requiring specific recognition not provided by rates and
ratingskills that are not rating-wide requirements.
Those special skills and knowledges required in specific
billets or manpower authorizations are categorized by
special NEC codes. These codes are identified by the
Chief of Naval Personnel (CHNAVPERS).
When the rating structure alone provides insufficient
information for manpower management purposes, the
NEC coding system more precisely identifies personnel
and manpower requirements. Management continually
compares the number of billets requiring special NEC
codes with the number of personnel who have the skills
and knowledges designated by those codes. It then uses
that comparison to plan and control the input of people
into the formal courses that prepare them for vacant
The official reference for NECs is the Manual of
NAVPERS 18068, Section II. For more information
about NECs, you may contact your division, department,
or command career counselor. Your career counselor or
your Personnel Support Detachment can provide you
with the latest information.
