TOPEKA, Kan. (AP) — The largest teachers union in Kansas plans to file a lawsuit after the July Fourth holiday challenging new education polices enacted by the legislature this spring. Those policies include the elimination of guaranteed tenure in public schools. Attorneys for the Kansas National Education Association say they intend to file the lawsuit in Shawnee County District Court. The union plans to contest the tenure issue and other provisions that were attached to a $129 million school funding bill by conservative Republicans and signed by Governor Sam Brownback. The KNEA supported the funding increases in the bill, which were aimed at complying with a Kansas Supreme Court decision. Other policies included loosening teacher licensing requirements and creating of a scholarship program for at-risk students funded by corporate donations in exchange for tax credits.
