A special instructional arrangement for students with disabilities residing in state schools shall be established by commissioner rule with a funding weight of 2.8.

(e) The commissioner by rule shall prescribe the qualifications an instructional arrangement must meet in order to be funded as a particular instructional arrangement under this section. In prescribing the qualifications that a mainstream instructional arrangement must meet, the commissioner shall establish requirements that students with disabilities and their teachers receive the direct, indirect, and support services that are necessary to enrich the regular classroom and enable student success.

(j) A school district that provides an extended year program required by federal law for special education students who may regress is entitled to receive funds in an amount equal to 75 percent, or a lesser percentage determined by the commissioner, of the basic allotment, or, if applicable, the sum of the basic allotment and the allotment under Section 48.101 to which the district is entitled for each full-time equivalent student in average daily attendance, multiplied by the amount designated for the student's instructional arrangement under this section, for each day the program is provided divided by the number of days in the minimum school year. The total amount of state funding for extended year services under this section may not exceed $10 million per year. A school district may use funds received under this section only in providing an extended year program.

(k) From the total amount of funds appropriated for special education under this section, the commissioner shall withhold an amount specified in the General Appropriations Act, and distribute that amount to school districts for programs under Section 29.014.

After deducting the amount withheld under this subsection from the total amount appropriated for special education, the commissioner shall reduce each district's allotment proportionately and shall allocate funds to each district accordingly.
