TOPEKA, Kan. (AP) — A commission charged with studying efficiencies in Kansas schools considered a proposal that would ban teachers from most collective bargaining. The proposed bill is one of several considered Monday by the K-12 Student Performance and Efficiency Commission. It would limit teacher negotiations to only wages, salaries and hours of work, even if the teachers union and Boards of Education agreed to negotiate on other issues. The Topeka Capital-Journal reports other draft legislation would allow districts to consolidate administrative services and others creating commissions to study district reorganization and district cash balances. The commission was created as part of a school finance bill during the last session to study whether the state is effectively spending its education dollars to benefit students. It will make recommendations to the Legislature next year.
