3.  Special  series  NECs–These  NECs  are  not related to any particular rating. They are used to identify billet requirements that do not have a rating description. Special series NECs are general in nature and can be held by several ratings. The following are examples of special series NECs: Instructor 9503 all ratings ASIS Combat System 9537 FT, ET, ST, Technician EW, IC, GM Collateral Duty Alcoholism 9521 all ratings Advisor Source Ratings Rating series NECs are assigned to qualified personnel in designated source ratings. They are also assigned to apprenticeship rates and striker-identified rates applicable to a designated source rating. Certain E-8/E-9 compressed ratings are not listed as source ratings for NECs; however, personnel advanced to E-8 or E-9 do not lose NECs previously assigned. You should not nominate or send your people to courses of instruction to earn NECs unless they are in the proper source rating or apprenticeship. For example, only personnel in the Photographer’s Mate (PH) rating may earn NEC PH-8144, Motion Picture/TV Director, because PH is the only source rating for that NEC. However, both PHs and Journalists (JOs), if otherwise qualified, can earn NEC PH-8146, Motion Picture Script Writer, because PHs and JOs are source ratings for that particular NEC. Personnel who already have a rating series NEC should not normally be nominated for, or sent to, a course of instruction to earn an additional rating series NEC. However, they may take the course if it is a logical progression from their earlier specialty training. They also may take the course if their NEC embodies an outdated technology or if they are in an approved program for a formal change in rating. Sequencing NECs Enlisted personnel on active duty may have up to five NECs. The first two, or primary and secondary, NECs (PNEC and SNEC) are reflected in section 4 (fig. 6-1) of the Enlisted Distribution and Verification Report (EDVR). Section 9 of the EDVR lists all five NECs a person may have. A sequence code is assigned to each NEC. NEC sequence code numbers range from 1 to 8, and only one sequence code number is assigned to an NEC. Entry series NECs are assigned sequence code number 1. All other NECs are assigned a code number 2 through 8. The lower the sequence code number, the higher the NEC priority; for example, sequence 2 takes precedence over sequence 3. If a person has two or more NECs with the same sequence code number, the NEC for which the person most recently qualified takes precedence, except in unusual circumstances. Justification for NECs Being Assigned to a Billet Justify equipment or billet function changes when you submit requests for assignment of an NEC to a billet or for changes to your authorized manpower NEC billets. Keep the following policy in mind when you consider changes or requests with regard to NEC assigned billets: Assign NECs only to billets authorized on Manpower  Authorizations  (MPAs),  OPNAV 1000/2, for source ratings for the NEC. Minimize secondary NEC assignments. If you need to assign a secondary rating series NEC to a billet, place the NEC that best describes the billet requirement in the primary NEC position. Adhere to minimum and maximum paygrades identified for the various NECs in the Manual of Navy Enlisted Manpower and Personnel Classifications and Occupational Standards, Section II, NAVPERS 18068E, when assigning NECs to billets. Enlisted Women’s Billet Designation In the interest of efficient distribution and use of personnel, procedures have been established to identify certain billets ashore requiring women petty officers. Conversion NEC WP-9999 identifies these billets. This NEC maybe used as either a primary or secondary NEC on MPAs. Shore billets designated for women petty officers are intended to ensure the assignment of enough women petty officers to fill certain functions of an activity. These functions involve the supervision, training, and counseling of enlisted women. Such billets include company commanders in Recruit Training Commands (RTCs) and billets in correctional centers where women are confined. Be aware of and identify billets qualifying for NEC WP-9999, and submit appropriate MPA change requests 6-3
