Topeka ? Statewide data presented to a Kansas commission studying school efficiency shows districts are hanging onto more cash.

Several members of the K-12 Student Performance and Efficiency Commission expressed concerns Friday about a $152 million increase in unspent balances from 2008 to 2014. But there weren’t enough votes to request a study of how money is carried over for use in future years.

Commission member Mike O’Neal noted that a 2011 state law was designed to make it easier to transfer unspent money into a fund where it can be spent on general expenses such as salaries. But data shows the size of those transfers dropped from $18.1 million in the 2011-12 school year to $6.3 million this year.

School officials say funding uncertainty is one reason for saving money.
