When replacing a grantee, unexpended balances of funds in the possession of such grantee in the fiscal year following the fiscal year for which the funds were appropriated may be transferred to the replacement grantee if the approved application of the replacement grantee provides for the continuation of the Head Start services without significant change to the same enrollees and their parents and undertakes to offer employment to the staff of the terminating grantee. A letter of concurrence in the change should be obtained from the terminating grantee whenever possible.
