all functions funded at Bureau schools by the Office;

all operation, maintenance, and repair funds for facilities and Government quarters used in the operation or support of elementary and secondary education functions for the benefit of Indians, from whatever source derived.

enable tribes and tribal organizations operating such schools, without reducing direct program services to the beneficiaries of the program, to provide all related administrative overhead services and operations necessary to meet the requirements of law and prudent management practice; and

carry out other necessary support functions which would otherwise be provided by the Secretary or other Federal officers or employees, from resources other than direct program funds, in support of comparable Bureau-operated programs.

reduce the amount of the grant determined under paragraph (1) to the extent that payments for administrative costs are actually received by an Indian tribe or tribal organization under any Federal education program included in the direct cost base of the tribe or tribal organization; and

take such actions as may be necessary to be reimbursed by any other department or agency of the Federal Government for the portion of grants made under this section for the costs of administering any program for Indians that is funded by appropriations made to such other department or agency.

conduct such studies as may be needed to establish an empirical basis for determining relevant factors substantially affecting required administrative costs of tribal elementary and secondary education programs, using the formula set forth in subsection (c); and

be conducted onsite with a representative statistical sample of the tribal elementary or secondary educational programs under a contract entered into with a nationally reputable public accounting and business consulting firm;

take into account the availability of skilled labor commodities, business and automatic data processing services, related Indian preference and Indian control of education requirements, and any other market factors found to substantially affect the administrative costs and efficiency of each such tribal elementary or secondary educational program studied in order to ensure that all required administrative activities can reasonably be delivered in a cost effective manner for each such program, given an administrative cost allowance generated by the values, percentages, or other factors found in the studies to be relevant in such formula;

identify, and quantify in terms of percentages of direct program costs, any general factors arising from geographic isolation, or numbers of programs administered, independent of program size factors used to compute a base administrative cost percentage in such formula; and

identify any other incremental cost factors substantially affecting the costs of required administrative cost functions at any of the tribal elementary or secondary educational programs studied and determine whether the factors are of general applicability to other such programs, and (if so) how the factors may effectively be incorporated into such formula.
