answer keys must be controlled and maintained by a commissioned officer, designated Chief Petty Officer (E-7/8/9) or an ESO at all times.  The ESO retains the NRTC answer keys listing the correct answer to each question. Controlling.  Answer  keys  must  be  closely controlled.  Answer keys require the same security as advancement examinations (BUPERSINST 1430.16). Report  loss  of  answer  keys  in  the  same  manner  as reporting  a  lost  advancement  examination.   Destroy answer  keys  using  local  instructions  for  destroying classified material. ESOs should keep answer keys in a locked safe and closely supervise access. Such control and supervision should not adversely affect any of the following situations:    Divisional  sub-custody  of  answer  keys  to commissioned officers or designated CPOs    Actual  grading  by  selected  enlisted  personnel, under the direct and continuous supervision of a commissioned  officer  or  designated  CPOs  and ESO    Local duplication of answer keys, provided they receive the same security as the originals Q4.   True  or  False.    You  may  locally  duplicate  the answer sheet provided in the back of an NRTC. Q5.    True  or  False.   Answer  keys  should  be  provided the same protection as advancement exams. GRADING COURSES The passing score for each NRTC assignments is 3.2. A  student  who  gets  a  failing  score  on  any assignment must rework that failed assignment.   The maximum score on a resubmission is 3.2.    ESOs record and report grades as follows:    Officer—Page 1070/613    Enlisted—Page 1070/604    Naval  Reserves  report  grades  via  Reserve Standard   Training   Administration   and Readiness Support (RSTARS) You may inform students of the correct answer to any  question  they  answer  incorrectly,  and,  you  may inform  the  student  on  what  page  they  may  find  the correct answer.  Do not return graded answer sheets to the student.  Graded answer sheets are destroyed by the ESO. ESOs   at   Naval   Reserve   centers,   Naval   Air Stations, and other Reserve-affiliated activities should ensure  inactive-duty  reservists  receive  appropriate retirement  points  for  courses  they  take. The  ESO should  refer  to  NAVEDTRA  12061  to  verify  proper retirement point credit. Q6.    What is the passing score for all assignments and courses? DISTRIBUTION STATEMENTS The  Naval  Education  and  Training  Professional Development  and  Technology  Center  (NETPDTC), assigns  distribution  statements  to  all  NRTCs.   ESOs should  be  familiar  with  the  various  distribution statements. They  are  used  to  determine  who  is authorized  to  request  certain  publications. The following is a brief summary of each statement:    Distribution Statement A:  Approved for public release; distribution is unlimited.    Distribution   Statement   B: Distribution authorized to U.S. government agencies only.    Distribution   Statement   C: Distribution authorized  to  U.S.  government  agencies  and their contractors.    Distribution   Statement   D: Distribution authorized to DoD and DoD contractors only.    Distribution   Statement   E: Distribution authorized to DoD components only. For  comprehensive  information  on  distribution statements,  refer  to  DoD  Directive  5230.24  and SECNAVINST 5510.36. Q7.    An NRTC that is approved for public release will have what distribution statement? CENTRAL ENROLLMENT—CHANGES IN COURSE ORDERING PROCEDURES Nonresident   training   courses   (NRTCs)   are normally ordered by individual commands that use the Naval  Supply  System  MILSTRIP  ordering  process. That process is being phased out as current stocks are depleted.   This  process  is  gradually  giving  way  to  a centralized  ordering  and  enrollment  process  that features direct contact between the Fleet and the Navy Advancement Center.  Sailors will “enroll” in courses instead of  “ordering” a course as before.  Once a Sailor is enrolled in a course, the Navy Advancement Center will print and ship the course.  Once enrolled, the Navy 4-3
