For years, families of students with disabilities in Colorado have navigated a frustrating gap in the law. A child whose anxiety, depression, autism, ADHD, sensory processing differences, or trauma made a full school day overwhelming might have been quietly placed on a “shortened day” — sometimes formally, often informally. The schedule might have helped. But the families on those schedules often had no clear protections, no return-to-full-day plan, and — perhaps most painfully — no shield against being labeled truant for the very accommodations their schools had handed them.
That gap is now closed.
In 2024, Governor Polis signed House Bill 24-1063 (Addressing Abbreviated School Days) into law. The statute — codified at C.R.S. § 22-20-123 — and the corresponding ECEA Rule 8.01(1)(j), effective May 12, 2025, fundamentally change how Colorado schools must approach reduced school day schedules for students with disabilities. As of July 1, 2025, every administrative unit in the state — every school district, BOCES, and the Charter School Institute — was required to adopt a policy “substantially similar” to the model policy published by the Colorado Department of Education (CDE) in April 2025.
If your child has an IEP or a 504 plan, this law matters to you. Here is what it does, what it requires, and what to do if your district isn’t following it.
What Is an “Abbreviated School Day”?
The statute defines an abbreviated school day as any school day during which a child with disabilities receives instruction or educational services for fewer hours than the majority of other students who are in the same grade and school as the child — whether the abbreviated day was planned or unplanned.
Two things in that definition deserve emphasis.
First, it is not limited to formally documented “shortened day” schedules. If a child is being sent home early, told not to come in until later, picked up before lunch, or kept out of certain blocks because the school cannot manage their behavior, that is an abbreviated school day under the statute — even if no one has called it that.
Second, it is not limited to particular disability categories. The protections apply to any child with a disability under the Individuals with Disabilities Education Act (IDEA) or under Section 504 of the Rehabilitation Act. A student with a serious emotional disability, a student with autism, a student with chronic illness, a student with a complex behavioral profile, a student recovering from trauma — all are squarely within the scope.
Who Decides Whether a Child Goes on an Abbreviated Schedule?
Under the new framework, only one body has the authority to design, approve, or extend an abbreviated school day: the child’s IEP Team or 504 Team. Schedule decisions cannot be made unilaterally by a principal, an attendance committee, a SARB (Student Attendance Review Board), or a behavior team operating outside the special-education process. The team must include the parents, must consider the child’s disability-related needs, and must document its decision.
This is a change of practice in many Colorado districts. Before HB24-1063, an abbreviated schedule could effectively be imposed by the school for the school’s convenience — to manage a behavior, to give staff a break, to “give the child a soft start.” That is no longer permissible. Schedule reductions for students with disabilities are now an IEP/504 question, made by the IEP/504 team, with the documentation that the IDEA and Section 504 require.
What the Team Must Do
When an abbreviated school day is being considered — whether the school proposes it or, more commonly, parents request it — the IEP or 504 team must do the following:
Document the disability-related basis for the schedule. The team must articulate, with reference to evaluations and data, why the child’s disability requires fewer instructional hours than peers receive. A vague reference to “behavior” or “attendance” is not enough.
Develop a written plan with clear outcomes. The plan must describe what the child needs to demonstrate, achieve, or stabilize before instructional time can be increased. “Outcomes” here means measurable goals — reductions in dysregulation episodes, increases in time tolerated in particular settings, mastery of regulation skills, and so on. The team must define what success looks like.
Define a step-by-step process for returning the child to a full school day. This is not optional. The default expectation under Colorado law is that abbreviated schedules are time-limited bridges to full attendance, not permanent reductions. The plan must include identifiable stages — incremental additions of instructional time tied to the outcomes — and the supports and services that will accompany each stage.
Issue Prior Written Notice. Whether the team approves or refuses an abbreviated day, federal law (34 C.F.R. § 300.503) requires the district to issue Prior Written Notice describing what was decided, why, what the team considered, what alternatives were rejected, and on what data. This is the document parents most need — and the document districts most often fail to produce.
Review the schedule regularly. The schedule is not a static placement. The team must monitor, review, and adjust as the child’s needs evolve.
The Truancy Protection — Why This Law Matters Right Now
Two passages in the statute are doing extraordinary work. They have transformed how disability-related attendance issues should be handled in Colorado, and they are not yet widely understood by families, advocates, or — frankly — many schools.
A child with disabilities who is appropriately placed on an abbreviated school day schedule by their IEP or 504 Team may not be considered truant or chronically absent based solely on the abbreviated schedule.
Colorado compulsory school attendance requirements do not apply to a child with disabilities appropriately placed on an abbreviated school day schedule by their IEP or 504 Team.
In practical terms: if your child’s reduced schedule has been properly approved by the IEP or 504 team, the missed instructional time is not truancy and cannot drive a truancy referral, a habitually-truant designation, or a court petition under Colorado’s compulsory attendance law (C.R.S. §§ 22-33-104, 22-33-107, 22-33-108).
This is a deliberate legislative choice. Colorado decided that students with disabilities should not be punished — and parents should not be threatened with court — for schedule needs that arise from the very disabilities the schools are obligated to serve. The truancy carve-out turns on whether the schedule has been “appropriately placed” by the IEP or 504 team. Districts that ignore the framework, refuse to convene the team, or impose schedules without documentation lose the protection — and risk both compliance liability and disability discrimination claims.
What If My Child Already Has an Informal “Late Start” or “Early Dismissal”?
Many families discover that their child has been on an unofficial abbreviated schedule for months or years. The school may have allowed late arrivals, encouraged early pickups, told parents not to push for full attendance, or carved out particular classes the child was “not required” to attend. Under the new law, those informal arrangements need to be formalized.
A formalized abbreviated school day schedule looks like this: the IEP or 504 team meets, decides on the schedule, documents the decision in the IEP or 504 plan, issues PWN, builds the return-to-full-day plan with outcomes and stages, and reviews regularly. An informal arrangement — by handshake, by email, by long-standing practice — leaves the family without the truancy protection, without a return plan, and often without recourse when the school changes its mind.
If your child is on an informal modified schedule, ask in writing for an IEP or 504 team meeting to formalize it under § 22-20-123. The meeting itself is not a concession; it is the process the law now requires.
What If My Child Needs an Abbreviated Schedule and the District Won’t Consider One?
This is increasingly the harder problem. As awareness of the law grows, some districts are quietly resistant — sometimes because of a culture against reduced schedules, sometimes because of staffing or program limitations, sometimes because they have not yet adopted a conforming policy.
If your district refuses to engage with the framework, the path forward is procedural and is outlined below in the order parents should typically pursue it.
First, put the request in writing. Identify the statute (C.R.S. § 22-20-123) and the rule (1 CCR 301-8, ECEA Rule 8.01(1)(j)). Ask for an IEP or 504 team meeting within ten school days. Reference the specific accommodations you want considered — a delayed start, a flexible entry window, a modified order of classes, structured morning transition support, transportation modifications, time-limited reductions tied to data.
Second, demand Prior Written Notice. If the team meets and refuses, or refuses to meet, federal law requires PWN. Insist on a PWN that addresses each of the elements required by 34 C.F.R. § 300.503. A document that just says “the team considered and denied the request” does not satisfy the regulation. The PWN must identify what data the district relied on, what alternatives it considered, and why it concluded the schedule is unnecessary for FAPE. Districts struggle to produce a defensible PWN in this context — and that struggle is itself useful evidence.
Third, ask for the district’s adopted abbreviated school day policy. Every administrative unit was required to adopt one by July 1, 2025. If your district has not — or cannot produce it on request — that itself is a separate compliance issue and is reportable to CDE.
Fourth, escalate through the available legal remedies.
A state-level complaint to the Colorado Department of Education (60-day investigation timeline) is often the fastest path to relief. CDE’s investigators will look at IDEA compliance, ECEA rule compliance, and PWN issues.
A complaint with the Office for Civil Rights, Region VIII (Denver) addresses Section 504 and ADA discrimination claims — particularly if the district is treating disability-related attendance issues with truancy rather than accommodation.
A due-process complaint under the IDEA, including invocation of the stay-put provision, is the most powerful remedy where the district is denying FAPE through schedule decisions or attempting to change placement without proper team action.
A request for an Independent Educational Evaluation at public expense can be appropriate when the district’s evaluation does not adequately address the disability-attendance link.
How This Law Connects to Truancy Court
Families dealing with truancy referrals know that proceedings can move quickly. A district that has not run the abbreviated school day analysis required by § 22-20-123 should not be permitted to obtain a truancy adjudication for absences that the analysis would have excused. Two arguments are particularly important:
The first is statutory. Under C.R.S. § 22-33-107(3), a school district must develop an appropriate plan that addresses the cause of attendance issues before initiating judicial proceedings. For a child with an IEP, that plan must come through the IEP team. A SARB-style “Attendance Improvement Plan” that demands perfect attendance from a student whose own IEP identifies disability-driven school refusal is not an appropriate plan within the meaning of the statute.
The second is the abbreviated-day exemption itself. If the district had run the analysis the law now requires, the resulting schedule would have been protected from truancy enforcement. A district cannot bypass that protection by refusing to do the analysis. Bringing a truancy petition without first considering the abbreviated school day framework is a form of disability discrimination — and a foundation for both procedural challenges and federal claims under Section 504 and ADA Title II.
Reporting and Transparency
Beginning July 1, 2026, CDE will require school districts to report annually on the number of students placed on abbreviated school day schedules, including demographic information. The data will be publicly available and shared with the state legislature. This is a meaningful accountability provision. It will, over time, surface districts that are over-relying on reduced schedules, districts that are not offering them at all, and disparities in who is being placed on them.
For families, the reporting requirement creates one more reason to insist on a formal team-approved schedule rather than an informal arrangement. Children on documented schedules will be counted, served, and reviewed under the new framework. Children on informal arrangements will not.
What Parents Should Do Now
If your child is on an informal modified schedule or experiencing significant attendance struggles tied to disability:
Request an IEP or 504 team meeting in writing. Identify the statute and rule. Bring data — your own observations, evaluation reports, mental-health records you choose to share. Ask the team to formally consider the abbreviated school day framework and to document what the law requires it to document. If the team approves a schedule, get the return-to-full-day plan in writing, with outcomes, stages, and review intervals. If the team refuses, demand PWN. And if the district will not engage, pursue the administrative remedies that exist precisely for this purpose.
Colorado’s new abbreviated school day law is one of the most significant changes in the state’s special-education framework in years. It exists because the legislature recognized that schedule and attendance issues are often disability issues — and that protecting these students requires moving the decision into the IEP/504 team, where it has always belonged, with the documentation, the planning, and the protections the law now provides.
