TOPEKA, Kan. (AP) _ Kansas ranks among the top 10 states in a study of government transparency, accountability and anti-corruption mechanisms. The state is one of 19 to receive an average grade of "C" in the State Integrity Investigation, conducted by the Washington-based Center for Public Integrity, Public Radio International and Global Integrity. The study found that states are doing a poor job delivering accountability and transparency to their residents. No state received an A from the months-long probe that looked at 330 ``Corruption Risk Indicators'' across 14 categories of government. Kansas scored a 75 in the study, ninth best in the nation, while Missouri also received a C grade with 72 points. New Jersey had the highest grade with a B-plus, while eight states received an F.
