TOPEKA, Kan. (AP) — It would seem a simple task. Write a check for $129 million and satisfy a Kansas Supreme Court ruling regarding the constitutionality of school funding.

But the process is proving difficult as legislators dive into the 20-year-old school finance formula, scanning about to look at various aspects of how $3 billion in state aid is distributed and whether the money is producing the desired results.

Republican Gov. Sam Brownback has asked for a clean funding bill before legislators leave town Friday, though he will look at changes to the formula. He wants something in place to meet the court’s July deadline for resolving the issue.

Legislators are looking a bit broader, but the governor’s likely opponent in November says lawmakers just need to write the check.
