A Republican-controlled state Senate committee spiked a bill Wednesday that was meant to spark a broad conversation about the future of Colorado’s public schools.

Some lawmakers hoped House Bill 1287 would help sell voters on raising taxes to better fund the state’s schools. But the Senate State, Military and Veterans Affairs committee voted 3-2 along party lines to kill the legislation, which would have created a series of committees to examine the state’s education laws and make recommendations for changing them.

Republicans objected to the bill because they didn’t want to create more bureaucracy, and they thought it was a ploy to raise taxes.

The bill’s demise was a defeat for a group of the state’s most authoritative lawmakers on education policy. It was one of the top legislative priorities for state Reps. Millie Hamner, a Dillon Democrat, and Bob Rankin, a Carbondale Republican. Both serve of the state’s budget committee and rallied lawmakers around the bill.

Rankin called the bill the most important of his legislative career.

“I’m bitterly disappointed, although it was expected,” he said. “I certainly don’t intend to give up. We’ve worked for over three years to move this idea forward. We thought we built a bipartisan coalition that was interested and wanted to help. We thought we were making really good progress.”

Hamner also expressed dismay over the bill’s death.

“To die quietly like that in Senate was really, really surprising and disappointing,” Hamner said. “Do we still have a need to establish a vision for the future of our kids? Yes. Apparently we’re going to have to do that without our Senate majority.”

Last-minute amendments brought by state Sen. Kevin Priola, a Henderson Republican, to address Senate GOP leadership’s concerns could not save the bill.

Supporters of the bill said the legislature needed to step in to help rethink Colorado’s education landscape holistically, not with piecemeal legislation. The state’s laws are outdated and clash with 21st century expectations, they said at Wednesday’s hearing.

“Our current collection of policies and laws have failed to keep pace with changes in expectations of our education system,” said Mark Sass, a Broomfield high school teacher and state director of a teacher fellowship program, Teach Plus. “We need a deliberate and collaborative conversation in our state, as to our vision of education.”

State Sen. Owen Hill, a Republican from Colorado Springs, said he supported the goal of the bill. His name was listed as a sponsor when the bill was first introduced. But he said he eventually concluded the bill was the wrong approach.

“I’m not sure this is the solution to get us there,” he said. “It’s time for us to take a bottom up approach. I get nervous about standing up and staffing and financing another government program.”

After the committee hearing, Sass said Republican lawmakers failed to realize their unique role in Colorado shaping statewide education policy. The state’s constitution gives no authority to the governor, the education commissioner or the State Board of Education to create a strategic plan.

“We need someone to drive this conversation,” he said. “If the legislature won’t, who will?”

Priola said in an interview that he had hoped for more time to lobby Senate leadership and members of the committee. Instead, he said he’d try again next year.

“We live in a state with 178 school districts and thousands of schools,” he said. “There can’t be one way of doing things, but there also can’t be 1,000. There has to be some commonality on what we’re doing and what direction we’re heading.”

Rankin was less committed in trying again next year.

“I want to think about,” he said. “I don’t think this elected, term-limited legislature with the background they come from can develop the kind of leadership needed for this movement.”

The death of House Bill 1287 puts another bipartisan piece of legislation on shaky ground.

House Bill 1340, sponsored by state Reps. Alec Garnett, a Denver Democrat, and Paul Lundeen, a Monument Republican, would create a committee of lawmakers to study and make changes to the way Colorado funds its schools.

The state House of Representatives was expected to hold its final vote on that bill Wednesday morning. But Democratic leadership pushed the vote by a day.

Some Democrats in the House saw the two bills as a package, while Republicans in the Senate saw them as competing. With partisan rancor flaring in the waning days of the session, House Democrats could return the favor and kill the finance study bill.

Rankin, the House Republican, said he hoped his chamber’s leadership would let the finance study bill move forward. He introduced a similar bill two years ago but was unable to get the bill through the legislative process.

“I think it’s a good idea to take a hard look at school finance. Maybe we can get some dialogue going,” he said, adding that he believes lawmakers still need to think about a strategic plan for its schools.

Hamner, the House Democrat, said she also supported the finance study.

“I think their bill will be just fine,” she said. “Unless the Senate decides to kill it in State Affairs.”
