TOPEKA, Kan. (AP) — A top Kansas education official and a school superintendent are testifying in a state district court hearing on a new school funding law.

They’re being quizzed by attorneys for four school districts suing the state over education funding.

The Dodge City, Hutchinson, Wichita and Kansas City, Kansas, districts are asking a three-judge panel to block the new law.

Their attorneys say Hutchinson Superintendent Shelly Kiblinger also will testify.

The new law took effect in April. It scrapped the state’s per-pupil formula for distributing aid to public school districts in favor of predictable “block grants.”

The state contends the changes provide stability. Critics question whether the state is providing a suitable education to every child.
