(a) (1) The transportation weighting of each school district shall be determined by the state board as follows:

(A) Divide the BASE aid amount for the current school year by the BASE aid amount for school year 2018-2019*;

(B) multiply the number of transported students by the per capita allowance that corresponds to the density figure for the school district as determined in subsection (a)(2);

(C) multiply the product obtained under subsection (a)(1)(B) by 1.00;

(D) multiply the product obtained under subsection (a)(1)(C) by the quotient obtained under subsection (a)(1)(A);

(E) divide the product obtained under subsection (a)(1)(D) by the current year BASE amount. The result is the transportation weighting of the school district.

(2) The per capita allowance shall be determined using the following chart:

(b) (1) For school years 2017-2018 through 2020-2021, the transportation weighting of the school district shall be either the product determined under subsection (a)(1)(E), or that portion of such school district’s general state aid for school year 2016-2017 that was attributable to the school district’s transportation weighting, whichever is greater.

(2) For school year 2021-2022, and each school year thereafter, the transportation weighting of the school district shall be the product determined under subsection (a)(1)(E).

(3) In no event shall the transportation weighting of the school district result in the portion of such school district’s state foundation aid attributable to the transportation weighting being in excess of 110% of such school district’s total expenditures from all funds for transporting students for the immediately preceding school year.

(c) For the purpose of providing accurate and reliable data on student transportation, the state board is authorized to adopt rules and regulations prescribing procedures that school districts shall follow in reporting pertinent information, including uniform reporting of expenditures for transportation.

(d) As used in this section:

(1) “Density figure” means the area of the school district in square miles divided by the number of transported students.

(2) “Transported students” means the number of students who were included in the enrollment of the school district in the preceding year who resided 21/2 miles or more by the usually traveled road from the school building such students attended and for whom transportation was made available.
