They are different. DODMETS, belongs to our exam Contractor, Concorde, Inc., Philadelphia PA. They subcontract out to over 460 exam centers across the country. That website deals strictly with the scheduling and completing of the medcial and optometric exams.
The DoDMERB website is where you will check the status of DoDMERB's evaluation....applicant meets medical sandards (qualified); does not meet medical standards (disqualified); remedial (either DoDMERB or in cases of an applicant who does not meet medical standards, the waiver authority), additional tests and/or consults and/or seeking additional information.
Thanks for asing the question. I hope I answered it to your satisfaction.
