The count of children will be extended to include children in county and local reformatories. prisons. and jails. To assure that children in such institutions participate in the benefits of title I programs. provision is being made to allow a State educational agency to assume responsibility for providing these services if the local education agency is unable or unwilling to do so. in which case the allocation on behalf of these children will be made to the public agency providing the service. The method of payment to a State for programs for migratory children of migratory workers will be changed to the number of children served in the State rather than on the number of children residing in the State so that maximum utilization will be made of the migrant funds available. An amendment is included to assure that grants can be made to local school districts on a timely basis under the advance funding authority by permitting the Commissioner of Education after April 1 to use the most reliable and recent data available to him on numbers of children and the use of the most recent per pupil expenditure data. rather than the second preceding years data as presently required. This amendment is needed in order to take full advantage of the advance funding provisions of the act.
