What Happens If a Missouri School Misses an IEP Deadline?

Deadlines in special education are not suggestions. Under the Individuals with Disabilities Education Act (IDEA) and Missouri's State Plan for Special Education, schools are legally required to meet specific timelines at every stage of the IEP process — from evaluation to annual review to service delivery.

When a school misses one of those deadlines, it is not just an inconvenience. It is a violation of your child's legal rights. And you have real options.

Before you can push back on a missed deadline, it helps to know exactly what the law requires. Here are the timelines that apply most often:

Initial evaluation — 60 calendar days. Once you provide written consent for an initial special education evaluation, the school has 60 calendar days to complete the evaluation and hold an eligibility meeting. (See our full guide: How Long Does a Missouri School Have to Evaluate My Child?)

IEP development after eligibility — 30 days. If your child is found eligible for special education, the school must develop an IEP within 30 days of that eligibility determination.

IEP implementation — as soon as possible. Once the IEP is finalized and you have provided consent for services, the school must begin implementing it without unnecessary delay. There is no specific number of days written into federal law, but courts and state agencies have consistently held that weeks of delay without explanation is a violation.

Annual IEP review — once every 12 months. The school must hold an IEP meeting to review and update your child's IEP at least once per year. If the annual review date passes without a meeting, the school is out of compliance.

Reevaluation — at least every 3 years. The school must reevaluate your child at least once every three years (unless you and the school agree in writing that a reevaluation is unnecessary). This is sometimes called a triennial evaluation.

Prior Written Notice — before any change. Before the school proposes or refuses to change your child's identification, evaluation, placement, or services, they must provide you with Prior Written Notice (PWN) in a reasonable amount of time. Failing to provide PWN before making a change is itself a procedural violation.

Under IDEA, procedural violations — including missed timelines — can constitute a denial of a Free Appropriate Public Education (FAPE) if they:

• Impeded your child's right to a FAPE
• Significantly impeded your opportunity to participate in the decision-making process
• Caused a deprivation of educational benefits

In plain terms: if the school's delay caused your child to go without services they were entitled to, or prevented you from being meaningfully involved in decisions about your child's education, that is a serious violation — not just a paperwork problem.

As soon as you suspect a deadline has been missed, start a written record. Note:

• The date you signed consent for an evaluation or services
• The date the deadline was supposed to pass
• Any communications with the school about the delay
• The impact on your child — missed instruction, regression, behavioral changes

Keep copies of every email, letter, and meeting notice. If you have only had verbal conversations with school staff, follow up in writing: "As we discussed on [date], I am noting that the IEP meeting originally scheduled for [date] has not yet taken place."

This paper trail is essential if you later need to file a complaint or request a hearing.

Send a written notice — email is fine, certified mail is better — to the special education director or building principal. State clearly:

• Which deadline was missed and when it passed
• What you are requesting (a rescheduled meeting, an immediate start to services, a written explanation)
• That you expect a response within a specific timeframe (five to ten business days is reasonable)

Keep your tone factual and firm. You are not accusing anyone — you are documenting a compliance issue and requesting resolution.

If the school does not respond or the issue is not resolved, you can file a State Complaint with the Missouri Department of Elementary and Secondary Education (DESE).

A state complaint is appropriate when a school has violated a specific provision of IDEA or Missouri special education regulations — including missing a legally required deadline. Here is how it works:

Who can file: Any individual or organization can file a state complaint on behalf of a child with a disability.

What to include: A written statement describing the violation, the child's name and school, and the facts supporting your complaint. You do not need a lawyer to file.

The timeline: DESE must investigate and issue a written decision within 60 days of receiving the complaint. They may extend this timeline by agreement or in exceptional circumstances.

What DESE can order: If DESE finds a violation, they can require the school to correct it — including ordering compensatory services to make up for what your child missed.

You can find the state complaint form and filing instructions on the DESE website under Special Education.

Mediation is a voluntary, confidential process in which a neutral third party helps you and the school reach an agreement. It is free to families under IDEA.

Mediation can be a faster and less adversarial path than a due process hearing, and it can be used alongside a state complaint — filing one does not prevent you from pursuing the other.

To request mediation in Missouri, contact DESE's Special Education Compliance office.

If mediation does not resolve the issue — or if the violation is serious enough that you need a binding legal decision — you can request a due process hearing.

A due process hearing is a formal legal proceeding before an impartial hearing officer. Both sides present evidence and arguments, and the hearing officer issues a written decision that is legally binding.

Key things to know:

Two-year statute of limitations. In Missouri, you generally have two years from the date you knew or should have known about the violation to file for due process.

Stay-put rule. While a due process proceeding is pending, the school must keep your child in their current educational placement unless you and the school agree otherwise.

Compensatory education. If the hearing officer finds that the school's missed deadline denied your child a FAPE, they can order the school to provide compensatory education — additional services to make up for what was lost.

Attorney's fees. If you prevail in a due process hearing, you may be entitled to recover reasonable attorney's fees from the school district.

Due process hearings are complex, and having an advocate or attorney by your side significantly improves outcomes.

One of the most important remedies available when a school misses an IEP deadline is compensatory education — services provided after the fact to make up for the educational benefit your child lost during the period of non-compliance.

Compensatory education is not automatic. You typically need to request it through a state complaint or due process hearing, and you will need to show that the delay caused your child to miss out on services they were entitled to.

Documentation of your child's progress (or regression) during the period of delay is critical to making this case.

Missed annual review meetings are one of the most common IEP violations — and one of the most overlooked. If your child's IEP anniversary date passes without a meeting, the existing IEP technically remains in effect, but the school is out of compliance.

Do not wait for the school to reschedule. Send a written request for the annual review meeting immediately, noting the date the review was due. If the school does not schedule the meeting within a reasonable time, that written request becomes part of your documentation for a state complaint.

Written notice to the school — First step. Document the missed deadline and request resolution in writing.

State complaint to DESE — File when the school has violated a specific legal requirement. DESE investigates and issues a decision within 60 days.

Mediation — Voluntary, free, and confidential. Can resolve disputes faster than a hearing.

Due process hearing — Formal legal proceeding with a binding decision. Appropriate for serious or unresolved violations.

Compensatory education — Services to make up for what your child missed. Request through complaint or hearing.

Missed IEP deadlines are stressful — but they are also actionable. The law is on your side, and there are clear steps you can take to hold the school accountable and get your child the services they are owed.
