ENLISTED DETAILERS AND USE OF THE DUTY PREFERENCE FORM, NAVPERS 1306/63 Learning Objective: When you finish this chapter, you will be able to— Identify the entries made on the Duty Preference Form, NAVPERS 1306/63. Every rate and, in most cases, every paygrade has a senior enlisted person who matches personnel within a particular rate or specialty with the available billets Navywide. This person is referred to as the enlisted detailer.  When  detailers  work  to  fulfill  requisitions (vacant billets), several factors are involved. To assign you to a billet, the enlisted detailer for your rate must match you with a billet you are qualified for and within a certain time frame. DUTY PREFERENCE FORM, NAVPERS 1306/63 You may sometimes ask yourself “How did I get the job I have now”? Your detailer had a lot to do with it, of course. However, the detailer determines what jobs you are qualified to hold by the information you submitted on your Enlisted Duty Preference Form, NAVPERS 1306/63. Your  detailer  has  access  to  your  Enlisted  Duty Preference Form and a record of your training through a computer terminal. The computer contains a record of the on-the-job and formal training you have received. Although you may not have total control over your training  and  qualifications,  you  are  completely responsible  for  the  information  the  duty  preference sheet contains.  You  are also responsible for submitting the form. 16-10 Student Notes:
