The Kansas City Public Schools revealed it falsified attendance data for three years in an effort to meet state accreditation standards.KCPS announced the findings of an internal investigation Wednesday. District leaders identified a circle of seven employees who changed student attendance records from 2013 to 2016.KCPS officials would not name them, but said four are on paid administrative leave and another three have since left the district.During the time period KCPS investigated, Vickie Murillo served as the district's chief academic and accountability officer.She left Kansas City to take the top job at Council Bluffs Community School District in mid-2017.The superintendent "was not aware of any irregularities in reporting," Council Bluffs district spokesperson Diane Ostrowski said Wednesday evening.Murillo has not responded to emailed questions from KETV NewsWatch 7."The Board of Education is not concerned about the matter in Kansas City," said Council Bluffs Community School District board president David Coziahr in a statement. "We are pleased with Dr. Murillo’s stellar leadership in the Council Bluffs Schools, and will remain focused on student achievement and all of the accomplishments we are celebrating with Dr. Murillo as our Superintendent."Murillo played an important role in helping KCPS reach accreditation standards, according to 2016 reporting from The Kansas City Star."Of course we feel really great about the growth and progress we have made," Murillo told the newspaper at the time. "We were strategic, we met students where they were and crafted a plant to make sure that students made growth and progress for the next year."Attendance records in Missouri help school districts earn accreditation scores. Falsified attendance records could mean KCPS owes the state money since it receives funding based on daily student attendance.A KCPS spokesman indicated legal action might be forthcoming with those individuals involved in tampering with the district's records. It was one of the reasons given to not name the circle of employees identified in the investigation.KCPS Superintendent Mark Bedell arrived in 2016 after the period of falsified records, according to the district."Please know that these actions, conducted by a few in our school district, and who are no longer working for our schools, cannot and will not be tolerated or accepted," Bedell said in a statement. "The findings within the report revealed an unhealthy culture within parts of the school district’s staff several years ago."
