Delaware Special Education Timelines: Every Deadline Parents Need to Know

Delaware's special education system runs on strict legal timelines. When a district misses them, your child loses services — and the district has violated the law. Most parents don't know these deadlines exist, let alone know how to enforce them. That gap is exactly what districts count on.

Here are every major timeline in the Delaware special education process, the regulation that backs it, and what to do when a district blows past it.

Evaluation Timelines

45 school days or 90 calendar days — whichever is less. Once a parent provides written, informed consent for an initial evaluation, the school district must complete the evaluation and convene an eligibility determination meeting within 45 school days or 90 calendar days, whichever comes first. This is codified in 14 DE Admin. Code §925.2.3.

The dual-metric structure is specifically designed to prevent districts from exploiting summer breaks. If you sign consent in May, a district cannot run out the clock by pointing to June, July, and August as school-day-free months. The 90-calendar-day outer limit forces action before fall.

What to do when missed: Document the date you signed written consent. If either deadline passes without an eligibility meeting, you have grounds for a state complaint. The DDOE regularly cites districts for evaluation timeline violations.

Reevaluations. Reevaluations — which must occur at least every three years unless the parent and district agree otherwise — follow the same procedural requirements. The district must obtain written consent before conducting any reevaluation (with limited exceptions), and timelines apply once consent is provided.

IEP Development and Meeting Timelines

IEP must be in place before services begin. For a child newly determined eligible for special education, the IEP must be developed and in effect before special education services begin. This is a non-negotiable sequencing requirement. Districts that delay the first IEP meeting after an eligibility determination are violating the law.

Annual review — within 12 months. The district must review your child's IEP at least once per year. The annual review meeting must occur within 12 months of the previous year's IEP effective date. A district that schedules the annual review late — even by a few weeks — may be technically out of compliance, which matters if you are building a state complaint record.

10-day notice for IEP meetings. The district must notify you of an IEP meeting early enough to give you an opportunity to attend. While IDEA does not specify an exact number of days, Delaware practice and DDOE guidance establish 10 days as the standard advance notice expectation. If you receive a meeting notice with less than 10 days' advance warning, request reschedule in writing.

PWN before implementing changes. After any IEP meeting that results in proposed changes to your child's program, the district must provide Prior Written Notice before implementing those changes. There is no fixed number of days, but "before implementation" is the legal standard — not "we'll send it eventually."

Dispute Resolution Timelines

State complaint: 60-day investigation. Once you file a state complaint with the DDOE's Exceptional Children Resources (ECR) workgroup, DDOE has 60 calendar days to investigate and issue a written decision. This 60-day clock starts when DDOE receives the complaint. Violations documented in the complaint that occurred more than one year before filing are outside the statute of limitations.

Due process: 15-day resolution session. When a due process complaint is filed, the district must convene a resolution session within 15 calendar days. This is the district's opportunity to resolve the dispute before a formal hearing. If the resolution session does not result in an agreement, a 30-day resolution period begins.

Due process: 45-day hearing timeline. If the dispute is not resolved within the 30-day resolution period, a 45-calendar-day timeline is triggered. The hearing panel must conduct the hearing and issue a final written decision within this window. Delaware uses a three-person panel — typically a licensed attorney, an educator, and a layperson.

Mediation: no fixed timeline. Mediation through the University of Delaware's SPARC program has no mandated timeline — it proceeds by mutual agreement of the parties and the mediator's schedule.

Part C to Part B Transition Timelines

Notification to school district — 90 days before third birthday. Child Development Watch (CDW), Delaware's Birth-to-Three early intervention program, must notify the local school district that a child is approaching age three. This notification triggers the district's obligation to begin the transition process.

Transition planning meeting — between 90 days and 9 months before third birthday. A formal transition planning meeting must occur within this window, involving parents, CDW coordinators, and school district representatives.

IEP in place by third birthday. If the child is determined eligible for Part B preschool special education services, the IEP must be fully developed and implemented by the child's third birthday. A child who turns three on a weekend or school holiday must have services in place when school next resumes.

Extended School Year (ESY) Decision Timeline

ESY decision within the annual IEP. Delaware requires the IEP team to make ESY determinations on an individualized basis as part of the annual IEP process. The decision cannot be made unilaterally by the district based on administrative policy. Under 14 DE Admin. Code §923.6.0, districts cannot limit ESY to specific disability categories, cap the type of services, or restrict eligibility by policy rather than by individual assessment.

What the team must assess: Regression during breaks, recoupment time needed when school resumes, and whether an emerging critical skill would be jeopardized without continuous summer intervention. If the IEP team fails to document this individualized assessment, the ESY determination may be challengeable.

Using Timelines as Advocacy Tools

The most effective way to use these timelines is proactively. When you submit any formal request — evaluation consent, IEP meeting request, records request — note the date in writing and note the applicable deadline. Follow up in writing as the deadline approaches. If the deadline passes, document the miss and consult the state complaint process.

Delaware's timeline violations are not technicalities. They are the mechanism by which children lose months of services they were legally entitled to. Every missed deadline is a potential compensatory education claim.

The Delaware IEP and 504 Advocacy Playbook includes letter templates that explicitly cite the regulatory timelines and are designed to put districts on notice that you are tracking compliance from day one.
