Title V provides financial assistance and flexibility to rural school districts that often lack the personnel and resources to compete for other federal grant programs, through two formula grant programs: Rural and Low-Income School (districts with high % of low-income students) and Small Rural School Achievement (districts with very low enrollment).
NCES catalogs districts as rural by first cataloging schools as city/town/suburban/rural and then looking across the "plurality" of locale types across a district's schools.
RLIS grants are based on the share of a state's count of low-income students in rural districts compared to the national count. This calculation uses SAIPE estimated percentages of low income children in a school's region and the Common Core of Data (CCD) provides the total enrollment by school. ACS provides the initial locale type (rural/urban) for the school's region.
SRSA (Small Rural School Achievement) provides a minimum grant to each eligible school, plus an additional grant per student after the first 50 in enrollment. The grant amount per school is capped at $60K and, as a last step, gets adjusted down based on Title II, Part A and Title IV, Part A amounts from two previous years. The calculation uses the CCD for the total enrollment by school, and the ACS for the initial locale type (rural/urban) for the school's region.
