  (17)  "Special education threshold" shall be calculated by dividing the total special education pupil count of every performance district that falls entirely above the bottom five percent and entirely below the top five percent of average daily attendance, when such districts are rank-ordered based on their current operating expenditures per average daily attendance, by the total average daily attendance of all included performance districts;

  (18)  "State adequacy target", the sum of the current operating expenditures of every performance district that falls entirely above the bottom five percent and entirely below the top five percent of average daily attendance, when such districts are rank-ordered based on their current operating expenditures per average daily attendance, divided by the total average daily attendance of all included performance districts.  The department of elementary and secondary education shall first calculate the state adequacy target for fiscal year 2007 and recalculate the state adequacy target every two years using the most current available data.  The recalculation shall never result in a decrease from the state adequacy target as calculated for fiscal years 2017 and 2018 and any state adequacy target figure calculated subsequent to fiscal year 2018.  Should a recalculation result in an increase in the state adequacy target amount, fifty percent of that increase shall be included in the state adequacy target amount in the year of recalculation, and fifty percent of that increase shall be included in the state adequacy target amount in the subsequent year.  The state adequacy target may be adjusted to accommodate available appropriations as provided in subsection 7 of section 163.031;
