Plaintiffs in the ongoing Kansas school finance lawsuit have told the state Supreme Court that some student test scores show the state is failing to fund its public schools adequately.

But attorneys for the state counter that funding is at record levels, that all schools are meeting state accreditation standards, and a court order for additional funding would be “a flagrant violation of the separation of powers.”

The Lawrence Journal-World reports both sides in the dispute filed briefs with the court Friday.

The Supreme Court could have a lot to say about what that new formula looks like and how much money needs to go into it when it weighs the two sides’ arguments and rules on the lawsuit later this year.

Oral arguments are Sept. 21.
