Crafting the budget signed Thursday by Gov. Jared Polis took months of work and started during former Gov. John Hickenlooper's administration.
It's not clear where from the budget the money will come from, but legislators vowed not to cut any money from education.
The legislation would provide an extra $65 million for roads and schools in the fiscal year that begins July 1.
It's the House's turn to take up the budget bill, and Democratic leaders there are skeptical of the late transportation compromise that moved the bill through the Senate quickly.
Democratic Majority Leader Steve Fenberg and Republican Minority Leader Chris Holbert brokered the compromise.
More than a decade ago, Colorado lawmakers promised to phase in full-day kindergarten as parents across the state demanded. It didn't happen.
Colorado funds just over half of a day of kindergarten — 0.58 percent to be precise. That means some school districts pay for free full-day kindergarten, while others charge families.
Unlike previous sessions, Democrats can now propose and pass their own health care agenda.
The new governor's campaign promise for free, full-day kindergarten took center stage. Polis requested $227 million out of a $33.7 billion budget.
The promise of affordable early childhood education was one of Colorado's new governor's biggest campaign pledges.
