(a) The at-risk student weighting of each school district shall be determined by the state board as follows:

(1) Determine the number of at-risk students included in the enrollment of the school district; and

(2) multiply the number determined under subsection (a)(1) by 0.484. The resulting sum is the at-risk student weighting of the school district.

(b) Except as provided in subsection (b)(4), the high-density at-risk student weighting of each school district shall be determined by the state board as follows:

(1) (A) If the enrollment of the school district is at least 35% at-risk students, but less than 50% at-risk students:

(i) Subtract 35% from the percentage of at-risk students included in the enrollment of the school district;

(ii) multiply the difference determined under subsection (b)(1)(A)(i) by 0.7; and

(iii) multiply the product determined under subsection (b)(1)(A)(ii) by the number of at-risk students included in the enrollment of the school district; or

(B) if the enrollment of the school district is 50% or more at-risk students, multiply the number of at-risk students included in the enrollment of the school district by 0.105; or

(2) (A) if the enrollment of a school in the school district is at least 35% at-risk students, but less than 50% at-risk students:

(i) Subtract 35% from the percentage of at-risk students included in the enrollment of such school;

(ii) multiply the difference determined under subsection (b)(2)(A)(i) by 0.7; and

(iii) multiply the product determined under subsection (b)(2)(A)(ii) by the number of at-risk students included in the enrollment of such school; or

(B) if the enrollment of a school in the school district is 50% or more at-risk students, multiply the number of at-risk students included in the enrollment of such school by 0.105; and

(C) add the products determined under subsections (b)(2)(A)(iii) and (b)(2)(B) for each such school in the school district, respectively.

(3) The high-density at-risk student weighting of the school district shall be the greater of the product determined under subsection (b)(1) or the sum determined under subsection (b)(2)(C).

(4) School districts that qualify to receive the high-density at-risk student weighting pursuant to this section shall spend any money attributable to the school district’s high-density at-risk student weighting on the at-risk best practices developed by the state board pursuant to Kan. Stat. Ann. § 72-5153(d), and amendments thereto. If a school district that qualifies for the high-density at-risk student weighting does not spend such money on such best practices, the state board shall notify the school district that it shall repay such money to the school district’s at-risk education fund. On or before January 15 of each year, the state board shall notify the house and senate standing committees on education, or any successor committees, which school districts had to repay such money and the amount of money such school district repaid for the preceding school year. If a school district does not spend such money on such best practices for three consecutive years, the school district shall not qualify to receive the high-density at-risk student weighting in the succeeding school year.

(5) The provisions of this subsection shall expire on July 1, 2027.

(c) The purpose of the at-risk student weighting and the high-density at-risk student weighting is to provide students identified as eligible to receive at-risk programs and services with evidence-based educational services in addition to regular instructional services.

(d) Upon a school district’s receipt of state foundation aid, that portion of such state foundation aid that is directly attributable to such school district’s at-risk student weighting and high-density at-risk student weighting, if any, shall be transferred to the district’s at-risk education fund established under Kan. Stat. Ann. § 72-5153, and amendments thereto.
