Is Colorado moving to evaluate teachers every three years?

July 21, 2026 • ~6 min read

Short answer: No — at least not yet. During the 2026 legislative session, Colorado lawmakers considered a bill (House Bill 1291) that would have let tenured teachers rated effective or highly effective receive a formal written evaluation once every three years instead of annually. It failed in the House Education Committee on a 10-3 vote, and the session adjourned without it becoming law. Annual evaluation remains the standard. But the fact that the idea got a serious hearing tells you something worth paying attention to, and the reasons it stalled are more instructive than the vote itself.

What the bill actually proposed

The proposal was narrower than the headlines suggested. It applied only to nonprobationary teachers — Colorado's equivalent of tenure, which a teacher earns after three consecutive years rated effective or highly effective. Those teachers, if they stayed in the top two rating tiers, would have moved to a written evaluation once every three years rather than every year. Anyone rated partially effective or ineffective would have stayed on the annual cycle, as would every probationary teacher still working toward nonprobationary status.

In practice that carve-out covered almost everyone. State data reported during the debate shows fewer than 4% of Colorado teachers landed in the bottom two tiers last year, so the three-year cycle would have reached the overwhelming majority of the veteran workforce.

Why it stalled

Two threads ran through the committee's decision, and neither was really about whether the paperwork is burdensome. Everyone seems to agree it is.

The first was cost. Colorado districts run evaluations through shared state software and data-collection systems, and shifting to a multi-year cycle carried an estimated first-year cost of $528,000 — a hard sell in a session already staring down a budget shortfall.

The second was harder to price: evaluation data is one of the few consistent, year-over-year signals a system has about whether teaching is holding up across every school and every group of students. Stretch the cycle to three years for most of the workforce, and you lose resolution on that picture right when you might need it. Several members put it plainly — the system may be flawed, but thinning the data wasn't the fix.

That's the real tension, and it's not unique to Colorado.

The workload problem the bill was trying to solve

Strip away the specifics and the bill was a response to a feeling every school leader knows: the observation is the part of evaluation that helps a teacher; the write-up afterward is the part that eats the evening. When leaders describe evaluation fatigue, they are almost never describing the time spent in classrooms. They are describing the translation that comes next — turning a page of walkthrough notes into formal, rubric-aligned, defensible prose for every teacher, several times a year.

Reducing frequency is one lever for that problem. It's just a blunt one, because it trades away the thing evaluation is for — regular, current insight into practice — to relieve a burden that lives almost entirely in the paperwork, not the observation. Colorado's committee, in effect, decided the trade wasn't worth it. That's a defensible call. It also leaves the underlying burden exactly where it was.

The framework underneath

Colorado's evaluation system traces back to Senate Bill 10-191, the 2010 law that built the Colorado State Model Evaluation System and its Teacher Quality Standards. The model uses a four-tier rating scale — ineffective, partially effective, effective, and highly effective — and ties nonprobationary status to a run of strong ratings. The original law leaned heavily on student growth measures, weighting them at roughly half of a teacher's rating; a later change (Senate Bill 22-070, 2022) reduced that weight and adjusted how consistently high-performing teachers are assessed.

Understanding that lineage matters, because HB 1291 wasn't proposing a new rubric or a new standard. The Quality Standards weren't on the table. Only the frequency of the formal write-up was. The instrument stays the same; the question was how often leaders have to produce the full document.

Where AI helps here — and where it doesn't

This is the distinction worth sitting with as a leader. If the burden you're trying to reduce is the observation itself — being in rooms, watching instruction, coaching teachers — then no tool should touch that, and you should be skeptical of anything that offers to. That work is the job.

But if the burden is the translation tax — the hours spent converting honest observation notes into standards-aligned written evaluations — that is a genuinely different problem, and it's the one where thoughtful AI use earns its place. It doesn't decide the rating. It doesn't sit in the room. It takes the evidence a leader already gathered and drafts it against the framework's language, so the leader edits rather than composes from a blank page.

Framed that way, the frequency debate almost dissolves. If the write-up for a strong veteran teacher takes minutes instead of an hour, the argument that you can only afford to do it every three years loses most of its force. You keep the annual signal Colorado's committee was unwilling to give up, without the annual paperwork cost that made the bill attractive in the first place.

What this means for school leaders

If you lead in Colorado, nothing changed for the coming year — plan on the standard cycle. If you lead elsewhere, watch this one anyway, because Colorado is not the only state where lawmakers are eyeing reduced evaluation frequency as workload relief. The pattern is spreading, and the counterargument Colorado surfaced (cost, plus loss of current data) travels with it.

The deeper takeaway is a reframe. The frequency conversation is really a proxy for a burden conversation, and burden and frequency are separable. A leader who attacks the paperwork directly is negotiating from a much stronger position than one asking to simply do the job less often.

How EvalScribe fits

EvalScribe exists for exactly the burden this debate is circling: it takes raw classroom observation data and produces formal, standards-aligned written evaluations, so the hours disappear from the write-up rather than from the observation cycle. The reclaimed time is the point — hours back for leaders, without asking anyone to watch teaching less often. If you want to put an actual number on it, the district capacity calculator does the arithmetic: minutes per write-up, times your teachers, times your observation cycles.

A note on scope, because it matters: EvalScribe supports a growing set of state evaluation frameworks, and dedicated builds for additional state models roll out over time. Whether a given state's specific instrument is live today is worth confirming directly rather than assuming. The principle above holds regardless of framework — the translation tax is universal — but coverage of any particular state's rubric is a question to verify, not to take on faith.

Frequently asked questions

Did Colorado pass a law changing teacher evaluation frequency in 2026? No. House Bill 1291 was rejected in committee, and the 2026 session ended without it becoming law. Annual evaluation remains the standard.

Who would the bill have affected? Only nonprobationary (tenured) teachers rated effective or highly effective. Teachers in the lower two rating tiers, and all probationary teachers, would have stayed on the annual cycle.

Why did it fail? Two main reasons cited in committee: the cost of updating state evaluation software and data systems during a budget shortfall, and concern about losing consistent year-over-year data on teaching quality across all student groups.

Does reduced frequency actually reduce a principal's workload? It reduces how often the formal write-up is required, but it doesn't address the write-up itself. The heaviest part of the burden — translating observation notes into rubric-aligned prose — is the same whether it happens once a year or once every three.

Colorado decided the fix wasn't fewer evaluations. The question it left open is whether the paperwork ever had to be the hard part in the first place.
