Will I have to be reboarded once I successfully meet height and weight standards?

Removal from the promotion standing list is covered by AR 600-8-19, Par 5-27; reinstatement to the promotion standing list is covered by Par 5-29. Soldiers removed from the promotion standing list for a valid enrollment into the Army Weight Control Program must be reboarded to regain promotable status.  Excerpt from AR 600-8-19 below:

5–29. Reinstatement to recommended list

A Soldier removed from a recommended list (see para 5–27 or 5–28, above) and later completely exonerated will be reinstated on the recommended list.  To be completely exonerated, the action that caused the initial removal must have been erroneous or should not have been imposed so the Soldier is free of any blame or accusation. For example, a Soldier receives a bar to reenlistment for failure to comply with AR 600–9 and is removed from the recommended list under paragraph 5–27b(3), above. Subsequent compliance with AR 600-8-9 and removal of the bar reenlistment does not mean that the action that caused the removal was erroneous. Therefore, the Soldier is not “completely exonerated” and reinstatement is not authorized. In no case will a reinstatement be delayed more than 30 days. If the Soldier would have been promoted had he or she not been removed from the list, he or she will be promoted when the next vacancy occurs for the Soldiers MOS and grade. If no vacancy is available, the Soldier may be promoted and reassigned to the IRR, if the Soldier requests it. The DOR for a Soldier promoted upon transfer from a unit to the IRR will be the date he or she would otherwise have been eligible for promotion. The effective date will be the date of the order.
