Lawmakers are considering restrictions on how often schools in need of additional funding can propose referendum measures to local taxpayers.

Carmel Clay and Lawrence schools won their referendums, but Center Grove Community schools was among four school districts in the state that failed to win voter approval for their measures.

Carmel Clay Schools is asking Hamilton County voters to approve a $40 million property tax increase in the state's first school safety referendum.

The Metropolitan School District of Lawrence Township is asking voters to approve a $191 million property tax increase on Election Day to pay for building improvements system-wide.

Thirteen referendum measures are on the ballot next week, and that list is split almost in half for construction-focused funding, and general operating measures.

Center Grove Community School Corporation is asking Johnson County voters to approve a property tax referendum on Election Day for $24.8 million to expand school safety measures.

The referendum aims to bring in an estimated $5 million a year for three years to fund school resource officers, teacher and staff training and mental health services for students.

The House Ways and Means Committee approved a bill this week to let schools ask for tax hikes for safety costs alone.

Republican state Sen. Travis Holdman of Markle says he'll introduce a bill in the 2019 legislative session that would allow schools to seek school-safety referendums that would work the same as operating referendums.

Earlier this month, state Sen. Travis Holdman (R-Markle) announced plans to file legislation that would add another funding option for schools: school safety referenda on local ballots.
