 Beginning with Class 38 (April–August 1958) college graduates and fleet sailors were integrated in each company, with all chief petty officers and warrant officers (W-1) placed in their own company.Today OCS classes are numbered by the federal fiscal year of their graduation (e.g., 09-19 would be the ninth class to graduate in fiscal year 2019).Presently those in training at OCS are mustered at the pay grade of E-5 unless they are prior enlisted already holding a higher pay grade.
