Dear , This is in reference to your application for correction of your naval record pursuant to Title 10, United States Code, Section 1552. After careful and conscientious consideration of relevant portions of your naval record and your application, the Board for Correction of Naval Records (Board) found the evidence submitted was insufficient to establish the existence of probable material error or injustice. Consequently, your application has been denied. A three-member panel of the Board, sitting in executive session, considered your application on 7 July 2020. The names and votes of the members of the panel will be furnished upon request. Your allegations of error and injustice were reviewed in accordance with administrative regulations and procedures applicable to the proceedings of this Board. Documentary material considered by the Board consisted of your application, together with all material submitted in support thereof, relevant portions of your naval record and applicable statutes, regulations and policies. In addition, the Board considered the advisory opinion contained in Chief, Bureau of Medicine and Surgery letter 5400 Ser M1/19UM10091 of 15 January 2020; a copy of which was previously provided to you for comment. Regarding your request for a personal appearance, the Board determined that a personal appearance with or without counsel will not materially add to their understanding of the issue involved. Therefore, the Board determined that a personal appearance was not necessary and considered your case based on the evidence of record. You requested to recalculate Entry Grade Credit (EGC) to include three years as a nurse and correct the Officer Appointment Acceptance and Oath of Office (NAVPERS 1000/4). The Board, in its review of your entire record and application, carefully weighed all potentially mitigating factors, to include your assertions. The Board agreed that you worked as a registered nurse from 6 July 2015 till 5 August 2018. The Board concluded that you were credited 1 year, 4 months, and 14 days of EGC correctly effective 30 March 2018; the day of the Professional Review Board (PRB), in accordance with OPNAVINST 1120.7A. In this connection, the Board substantially concurred with the comments contained in the advisory opinion. It is regretted that the circumstances of your case are such that favorable action cannot be taken. You are entitled to have the Board reconsider its decision upon submission of new matters, which will require you to complete and submit a new DD Form 149. New matters are those not previously presented to or considered by the Board. In this regard, it is important to keep in mind that a presumption of regularity attaches to all official records. Consequently, when applying for a correction of an official naval record, the burden is on the applicant to demonstrate the existence of probable material error or injustice.
