Dear : This letter 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 the entire record, 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, as well as applicable statutes, regulations, and policies. The Board also considered the enclosed 10 April 2019 advisory opinion (AO) furnished by the Marine Corps Performance Evaluation Review Board (PERB), which was previously provided to you. Although you were afforded an opportunity to submit a rebuttal, you did not do so. The Board carefully considered your request to remove your fitness report for the reporting period 3 January 2018 to 17 January 2018. The Board considered your contention that you received an adverse academic report due to an erroneous physical fitness test (PFT) failure, although the failure was due to a preexisting medical condition verified by proper medical authority. You also contend that, due to your injury, you should have been credited with a partial PFT and subsequently, been medically dropped from Drill Instructor (DI) School. The Board, however, substantially concurred with the PERB. The AO noted that your PFT failure was arguably related to a medical condition that became pronounced during the course of the run portion of the test. However, you knew of the condition prior to the test and chose to withhold your concerns. Although you offer alternative courses of action, to include an opportunity to retake the PFT, the Board determined that this option is viable for normal home station situations (and was in fact implemented upon your return from temporary duty), but is not viable for the unique environment of Drill Instructor School. With regard to your contention that you should have been credited with a partial PFT, the Board determined that attendance at DI School is contingent on passing all events on the PFT. With regard to your contention that you should have been medically dropped, the Board determined that students at DI School are in fact medically dropped, however, the issue must be identified and documented prior to actual conduct of the scheduled PFT. The Board thus determined that the report was administratively correct, procedurally complete and valid at the time of submission, and remains as such. The PERB determined, and the Board concurred, that you failed to meet the burden of proof necessary to establish an inaccuracy or injustice warranting removal of the report. 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 the 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.
