Summary
At a recent Hillsboro R-III Board of Education meeting Superintendent Dr. Isaacson praised a well-attended summer school, noted the board’s MSBA governance award, and warned that Senate Bill 3’s property-tax credit could freeze assessed values and push local tax rates higher if upheld.
At a regular meeting of the HILLSBORO R-III Board of Education, Superintendent Dr. Isaacson summarized summer programs, recognized the board’s award from the Missouri School Boards Association and outlined concerns about pending state legislation that he said could raise local tax rates.
Dr. Isaacson said summer school “has gone extremely well,” thanked staff and transportation personnel and noted strong attendance. He also congratulated the board for receiving the 2025 MSBA Governance Team Award, saying the honor recognizes “exceptional leadership, commitment to effective governance, continuous professional learning, and strong legislative advocacy.”
The superintendent spent most of his remarks on Senate Bill 3, a property-tax credit proposal. He said the bill’s mechanism — which would freeze assessed values for existing properties — appears straightforward but could have broad fiscal effects. “It’s the macroeconomics of our assessments being frozen … the tax rates are going to go up,” Dr. Isaacson said. He warned that with assessments frozen and values below market in parts of the district, tax rates could increase to maintain revenue, shifting more of the tax burden to new transactions and commercial properties. He said that could depress local home values and slow construction activity tied to school projects.
Dr. Isaacson said he has been discussing the matter with state legislators, including meetings earlier the same day, and expects court challenges. He added that the district is monitoring court and legislative developments and will report back as situations change.
On federal advocacy, Dr. Isaacson said he will travel to Washington in early July with other superintendents to meet members of Missouri’s congressional delegation and raise federal funding issues that affect the district. He said topics will include “arbitrage issues and some other federal funding issues” and that representatives from small, large and rural districts will discuss how federal decisions affect local schools.
The superintendent also noted routine items in his report: a summary of superintendent goals and limited early-childhood updates that the district plans to address at the next meeting.
The board did not take formal action on the legislative points; Dr. Isaacson framed them as informational and as an issue the district will continue to monitor.
