RESERVE LDO/CWO APPLICATION PROCESS
Utilize the Application Template located on the right side of this page.
Under Current Guidance on the right side of this page, read OPNAVINST 1120.12, OPNAVISNT 1420.1B, and annual NAVADMIN. Go over them carefully during your application process, making note of sections applicable to you as an individual candidate. These are your source documents for submitting an application. Only language or policy promulgated by the annual NAVADMIN message for the current application cycle will override what is written in the OPNAV instructions.
The application is your resume to the board demonstrating your potential for selection as a Naval Officer. The format is standardized as selection board members must sort through hundreds of them, and it is easier if they are all alike. Think of your package as one of many applications for the same great job -- you have to beat out the competition. You won't get extra points for excess. Do not include information that is already in your service record unless required by the OPNAVIST 1120.12, OPNAVISNT 1420.1B, or the annual NAVADMIN. However, you may include (but not required) your civilian resume as an enclosure in your package.
There are no "required" or "right" correspondence courses. A good blend of technical/non-technical courses will help, especially if done over a number of years and not just since you decided to apply. Consider taking enlisted rating courses of the other source ratings that are also in the normal path of advancement for the designator for which you are applying. Candidates may submit commendatory correspondence after submission of the application until 15 December of the year in which the board is scheduled to convene.
Seek out a Mustang mentor who you can consult with. An LDO or CWO in your desired designator can assist and ensure your application is ready for submission. Listen to what they say -- they have been there. Make sure your Command Coordinator is part of any dialogue when you have discussions that pertain to your package or questions you might have about the application process.
Community Point of Contacts can be emailed using the designator links at the top of this page.
DESIGNATOR SPECIFIC REQUIREMENTS
(1) All applicants applying to the 7158 designator must hold NEC O26A or O23A. No exceptions will be considered.
(2) All applicants applying to the 7178 designator must hold NEC O52A. No exceptions will be considered.
(3) Applicants applying for the 7818 designator are limited to CTT, CTR, and CTI ratings. No exceptions will be considered.
(4) Applicants applying for the 7828 designator are limited to IT, ET, and CWT ratings. No exceptions will be considered.
THE INTERVIEW BOARD
The interview board helps the Commanding Officer (CO) evaluate the candidate's potential as a career officer. The CO's recommendation should be consistent with the board's comments or an explanation should be provided.
The annual NAVADMIN is very specific in addressing the board's purpose and composition. Designator and rank of the interviewer must be entered in the lower right hand block of the NEW LDO/CWO Interviewer's Appraisal Sheet (NAVPERS 1420/6).
Interviewers need to read and follow the information outlined on the NEW LDO/CWO Interviewer's Appraisal Sheet (NAVPERS 1420/6).
The OCM encourages Appraisal Board members provide applicants with verbal feedback at the conclusion of the interview and provide the completed interview form to unit COs/OICs for routing.
Interview appraisal boards shall be constructed of only three Reserve officers. LDO/CWO Appraiser only (no exceptions, even if on AC orders). The names of the approved appraisal board members must be included in the CO/OIC endorsement.
Every effort (including teleconference media) should be made to ensure the board members are from the LDO or CWO designator's competitive category for which the applicant is applying. The senior member of the interview panel for LDO applicants must be a lieutenant commander or above. The senior member of the interview panel for CWO applicants must be a CWO4 or above.
Minimum grade requirements for board members are lieutenant or CWO3. CWO3 panel members must have at least three years time in grade (at the time of interview). The interviewing board should, whenever possible, be comprised of officers who are not in the applicant’s command, or at minimum, not directly in the chain of command.
If it is not possible to assemble a panel of three officers, the interviews may be conducted separately. Only three interview appraisals are required for each applicant.
Interview appraisal board member preparation for applicant appraisal boards is an important part of the board process. Review of the application, review of discrete requirements for the applicant designator, having well thought out questions on technical expertise, leadership, and knowledge of the designator for which the candidate is applying, to include future career path if selected, are all great examples of board member preparation.
Each appraisal must contain the names of all three-panel members.
The technical ability and potential blocks on the interview appraisal sheet must be marked for LDO and CWO candidates.
The CO of either SEAL Team 17 or 18 are required to endorse applicants for both the 715X and 717X designators.
CO's ENDORSEMENT
The CO's Recommendation is critical. It must be specific as to why an applicant is better than his/her competition -- hard to do if not true. Weak praise may hurt the candidate. If the CO does not recommend a candidate for commissioning, the application should not be forwarded by the command.
An applicant must be recommended by the CO to be eligible for consideration. If the applicant is applying for two designators, the CO's recommendation must address qualifications for both as outlined in the respective discrete requirements. If the candidate is not professionally competitive, he/she should be advised on ways to improve.
Recommendation must be personally signed by the CO, not "By direction". The CO's recommendation verifies the accuracy of the applicant's statements, as well as all enclosures.
CO's endorsement must contain specific statements that are outlined in the annual NAVADMIN.
Applicants currently serving on mobilization orders may have their application endorsed by their field commander. All applications endorsed by field commanders must have concurrence of their parent command.
IN-SERVICE PROCUREMENT BOARD
LDOs and CWOs are selected for appointment by In-Service Procurement Selection Boards. A new board is convened each fiscal year, usually in January, for approximately three weeks. The results are normally released to the fleet via NAVADMIN message in February. LDO Selectees are commissioned 1 October of the FY selected. CWO Selectees are commissioned 1 November of the FY selected. Details are included in the message.
In addition to senior LDOs, board membership includes officers of the line and various staff corps to allow the senior member of the board to establish internal panels with a good knowledge of the requirements of each occupational specialty. Each member of the board is sworn to select the best qualified candidates without prejudice or partiality.
In-service boards consider applicants for appointment in the designator (s) they have requested. If a candidate requests consideration in more than one designator (the maximum that can be requested is two), the board recommends the individual for appointment only in the designator for which he or she is considered best qualified.
The board recommends candidates for appointment in numbers not to exceed the quotas furnished by the Chief of Naval Personnel. However, the board is not obligated to select to the numbers provided if, in its opinion, sufficient numbers of applicants are not qualified for appointment in a particular designator.
ELIGIBILITY - GETTING STARTED
Again, you must read and be familiar with the OPNAVIST 1120.12 and the annual NAVADMIN. Go over it carefully before starting your application, making note of sections applicable to you as an individual candidate.
