PUBLIC LAW 103-382—OCT. 20, 1994 108 STAT. 3565 In addition, the State educational agency shall provide assurances that a procedure will be established through which local educational agencies dissatisfied with the determinations made by the State educational agency may appeal directly to the Secretary for a final determination. Beginning in fiscal year 1999, grants shall be calculated by the Secretary on the basis of population data compiled for local educational agencies, unless the Secretary and the Secretary of Commerce determine that use of the updated population data would be inappropriate or unreliable taking into consideration the recommendations of the study to be conducted by the National Academy of Sciences. If the Secretary and the Secretary of Commerce deter- Reports, mine that some or all of the data referred to in this paragraph are inappropriate or unreliable, the Secretaries shall jointly issue a report setting forth their reasons in detail. In years when grants are calculated by the Secretary on the basis of local educational agency data, for each local educational agency serving an area with a total population of at least 20,000 persons, the grant under this section shall be the amount determined by the Secretary. For local educational agencies serving areas with total populations of fewer than 20,000 persons, the State educational agency may either— "(i) distribute to such local educational agencies grants under this section equal to the amounts determined by the Secretary; and "(ii) use an alternative method, approved by the Secretary, to distribute the share of the State's total grants under this section that is based on local educational agencies with total populations of fewer than 20,000 persons. Such an alternative method of distributing grants under this section among a State's local educational agencies serving areas with total populations of fewer than 20,000 persons shall be based upon population data that the State educational agency determines best reflect the current distribution of children in poor families among the State's local educational agencies serving areas with total populations of fewer than 20,000 persons. If a local educational agency serving an area with total population of less than 20,000 persons is dissatisfied with the determination of its grant by the State education agency, then such local educational agency may appeal this determination to the Secretary. The Secretary must respond to this appeal within 45 days of receipt. "(3) PUERTO RICO.— For each fiscal year, the Secretary shall determine the percentage which the average per pupil expenditure in the Commonwealth of Puerto Rico is of the lowest average per pupil expenditure of any of the 50 States. The grant which the Commonwealth of Puerto Rico shall be eligible to receive under this section for a fiscal year shall be the amount arrived at by multiplying the number of children counted under subsection (c) for the Commonwealth of Puerto Rico by the product of— "(A) the percentage determined under the preceding sentence; and " (B) 32 percent of the average per pupil expenditure in the United States.
