No....it would be uber stupid to ever discontinue Gilead as it is a recognized as an international school (read-Mormon BYU potential)
The Governing Body has outlined adjustments to the Watchtower Bible School of Gilead. Starting with the 132nd class, which began on October 24, 2011, training will be given only to couples who are already in special full-time service, such as field missionaries who have not yet attended Gilead, special pioneers, traveling overseers, and Bethelites. If a couple speak and write English fluently, their Branch Committee may recommend that they attend.
Gilead graduates will be given assignments that will strengthen and stabilize the field and branch organization, whether as field missionaries, traveling overseers, or Bethelites. Those assigned to serve in the field will be used in densely populated areas where they can have the most profound effect on the preaching activity and on congregation activities. Branch Committees may continue requesting Gilead graduates if there is a particular need in their territory. They may also recommend well-qualified special full-time servants from their own branch territory to attend Gilead School. In some cases, Branch Committees may request that the graduates return to that country after they graduate
