TOPEKA, Kan. (AP) — The Kansas Senate has given first-round approval to a bill that would continue a statewide property tax for public schools for another two years.

Senators advanced the measure Thursday on a voice vote. The bill would raise $635 million for schools during the 2017-18 school year and another $663 million for 2018-19.

The Senate planned to take a final vote Friday to determine whether the bill goes to the House.

Kansas has imposed a statewide property tax to raise money for schools since 1992. The Kansas Supreme Court has said the state constitution prohibits lawmakers from imposing it for more than two years at a time.

The tax is $20 for every $1,000 of a property’s assessed value. The first $20,000 of a home’s value is exempt
