The purpose of this part is to set forth policies and procedures for the selection, initial funding and refunding of Head Start grantees and for the selection of replacement grantees in the event of the voluntary or involuntary termination, or denial of refunding, of Head Start programs. It particularly provides for consideration of the need for selection of a replacement grantee where the continuing eligibility (legal status) and fiscal capability (financial viability) of a grantee to operate a Head Start program is cast in doubt by the cessation of funding under section 519 of the Act or by the occurrence of some other major change. It is intended that Head Start programs be administered effectively and responsibly; that applicants to administer programs receive fair and equitable consideration; and that the legal rights of current Head Start grantees be fully protected.
