All - the team up here will "slate" (pencil in) folks into future OCS class dates for planning and class loading purposes, but that is not official until a Final Select letter with "OFFICIAL" OCS class convene date is generated and issued to the Recruiters for printing out and issuance to applicants. We might pencil in applicants 4-5 months out, but wont release the Final Select letter until ~3 month out to allow us the ability to move folks around should a need arise (someone declines and falls-out, an age critical shipper needs to ship, etc). An applicant's OCS date is not official until the Final Select letter is released. The chances of a penciled-in tentative date changing is often very, very, very small. The majority of the time that we change an OCS date from what was penciled-in to what eventually comes out in the FINSEL letter is most often at the request of the applicant (wants to ship later, needs to ship eariler due to age, etc). The applicant often knows what is going on (through their recruiter) and concurs with the change in OCS date. So if either your recruiter or someone up here at NRC (even me) tells you that you are slated or penciled-in for an OCS date, you should have high confidence that that date will be the date in your FINSEL letter. But that penciled-in date told to you verbally is not official until it comes out in your FINSEL letter. Hope this makes sense.
