(a) On or before July 1, 2021, the legislature shall:

(1) Consider the information reviewed pursuant to subsection (b), and determine if any provisions of this act are not reasonably calculated to provide adequate educational opportunities to every K-12 public education student in Kansas.

(2) (A) Review the school year 2020-2021 BASE aid amount and evaluate whether such BASE aid amount is reasonably calculated to have all students meet or exceed the educational goal set forth in Kan. Stat. Ann. § 72-3218(c), and amendments thereto.

(B) Such evaluation shall be based on a successful school model that identifies successful school districts based on the percentage of at-risk students in such districts in relation to the following outcomes:

(i) The percentage of students at grade level on state math and English/language arts assessments;

(ii) the percentage of students that are college and career ready on state math and English/language arts assessments;

(iii) the average composite ACT score; and

(iv) the four-year graduation rate.

(C) Such evaluation shall identify school districts that exceed expected outcomes and shall also identify school districts that have an average scaled difference on the outcome measures greater than or equal to one standard deviation from the average scaled difference of all districts. Those school districts that are identified as successful school districts in relation to other similarly situated districts may be used to evaluate whether the BASE aid amount is reasonably calculated to ensure that students will continue to meet or exceed the educational goal set forth in Kan. Stat. Ann. § 72-3218(c), and amendments thereto.

(b) (1) On or before July 1, 2018, the house and senate standing committees on education shall review the low enrollment weighting and the high enrollment weighting, as such terms are defined in Kan. Stat. Ann. § 72-5132, and amendments thereto, and alternatives to such weightings, including, but not limited to, a sparsity weighting. Such review shall be to ensure that the weightings are reasonably calculated to have students meet or exceed the educational goal set forth in Kan. Stat. Ann. § 72-3218(c), and amendments thereto.

(2) On or before July 1, 2019, the house and senate standing committees on education shall review the following:

(A) Reports submitted to the legislature pursuant to Kan. Stat. Ann. §§ 72-5170, 72-5171 and 72-296, and amendments thereto; and

(B) the legislative post audit reports conducted pursuant to Kan. Stat. Ann. § 72-5173, and amendments thereto, that were completed prior to July 1, 2019.

(3) On or before July 1, 2020, the house and senate standing committees on education shall review virtual school programs and the virtual school state aid calculation as described in Kan. Stat. Ann. § 72-3715, and amendments thereto.

(4) On or before July 1, 2021, the house and senate standing committees on education shall review the at-risk student weighting, as such term is defined in Kan. Stat. Ann. § 72-5132, and amendments thereto, to ensure that such weighting is reasonably calculated to have students meet or exceed the educational goal set forth in Kan. Stat. Ann. § 72-3218(c), and amendments thereto.

(5) On or before July 1, 2023, and on or before July 1, 2026, the house and senate standing committees on education shall review the successful school model described in this subsection (a) to review whether it is an effective model in determining successful schools and to ensure the BASE aid amount is reasonably calculated to meet or exceed the educational goal set forth in Kan. Stat. Ann. § 72-3218(c), and amendments thereto.

(6) On or before July 1, 2024, the house and senate standing committees on education shall review the bilingual student weighting, as such term is defined in Kan. Stat. Ann. § 72-5132, and amendments thereto, to ensure that such weighting is reasonably calculated to have students meet or exceed the educational goal set forth in Kan. Stat. Ann. § 72-3218(c), and amendments thereto.
