Mo. Rev. Stat. § 161.209
The department of elementary and secondary education has an affirmative duty to seek comment on its rules, regulations, and policies after their final approval or implementation. The department shall undertake such review on existing rules, regulations, and policies on an ad hoc, periodic basis with a priority given to such rules, regulations, and policies that could successfully be revised without affecting student achievement to accommodate periods when there is no increase in the appropriation for basic state aid funding pursuant to section 163.031, RSMo, from one fiscal year to the next or when withholdings of appropriated funds result in a situation equivalent to no increase in such appropriation.
