   2. (2)Assure that necessary services are provided by VA during the extended evaluation.

3. (c)Continuation in extended evaluation status. A veteran's case will be in extended evaluation status during periods in which:
   1. (1)The veteran is pending induction into the facility at which rehabilitation services will be provided;
   2. (2)The veteran is receiving rehabilitation services prescribed in the IEEP (§ 21.86); or
   3. (3)The veteran is on authorized leave of absence during an extended evaluation.
4. (d)Termination of extended evaluation status. A veteran in extended evaluation status will remain in that status until one of the following events occur:

      2. (ii)Declines or refuses to enter the program; or
      3. (iii)Defers induction for a period exceeding 30 days beyond the scheduled date of induction, except where the deferment is due to illness or other sufficient reason;
   2. (2)VA determines the reasonable feasibility of a vocational goal for the veteran before completion of all of the planned evaluation because the decision does not require the further evaluation;
   3. (3)The veteran completes the extended evaluation;
   4. (4)Either the veteran or VA interrupts the extended evaluation;
   5. (5)Either the veteran or VA discontinues the extended evaluation; or
