DENVER - Colorado's governor will sign a bill Tuesday overhauling the state's education system.
However, the changes will only take effect if Colorado voters approve about $1 billion a year in higher taxes.
The tax question will be petitioned onto ballots by advocacy groups, so it's too soon to say what exactly the proposed tax would be. Governor John Hickenlooper has said he'll push for the higher tax because schools need the upgrades.
The changes aim to reverse years of underfunded public schools and pay for statewide full-day kindergarten.
