Amend Floor Amendment No. 21 by Williams to CSHB 3 in SECTION __.01 of the article proposed by the amendment by striking proposed Subsection (b), Section 403.351, Government Code, and substituting the following: (b) The amount distributed in a fiscal year shall be apportioned among the school districts in amounts that, using the total taxable value of property in each district determined under Subchapter M for the most recent year for which the information is available, would permit each district to reduce its maintenance and operations tax rate for the tax year that ends in that fiscal year from the rate adopted by the district in the preceding tax year by the same percentage as each other school district. The comptroller may not distribute to a school district in a fiscal year an amount that, when added to the taxes that would be generated by the district for the tax year that ends in that fiscal year using a maintenance and operations tax rate of 75 cents, and to the state funds that would be distributed to the district under Chapter 42, Education Code, for the school year beginning in that tax year using that tax rate, would provide an amount per student in weighted average daily attendance for that school year that exceeds the amount of state funds distributed under Chapter 42, Education Code, and this section and maintenance and operations taxes of the district per student in weighted average daily attendance that would have been available to the district in the preceding year if the funding elements for Chapters 41 and 42, Education Code, for the current year had been in effect for the preceding year.
