DC IEP Process: The 120-Day Timeline for DCPS and Charter School Parents

Federal IDEA uses a 60-calendar-day evaluation baseline after parental consent. DC uses a 120-calendar-day window from signed parental consent through evaluation, eligibility, IEP development, and service initiation, with the AED meeting occurring before that clock within 30 days of referral. If you are starting the process or watching the school miss its deadlines, this is the map.

Why DC Has a 120-Day Timeline Instead of 60

Federal IDEA sets a 60-day evaluation baseline after parental consent. DC's process under 5-A DCMR §§ 3000–3099 uses a 120-calendar-day period from signed parental consent through evaluation, eligibility determination, IEP development, and service initiation; the AED meeting occurs before that period, within 30 days of referral.

The extended timeline reflects DC's complexity: DCPS is a large urban district with a separate school system running in parallel (60+ independent charter LEAs), a population with significant socioeconomic disparities, and a history of special education non-compliance that has generated more state complaints per 10,000 students than any other state or territory. More time in theory gives the process room. In practice, it can mean children wait months before services start — which is why submitting your written request as early as possible matters.

Stage 1: Written Referral and Child Find (Before the Consent Clock Starts)

The 120-day timeline does not start automatically. It begins when you sign written parental consent to a comprehensive special education evaluation.

A verbal conversation does not start the referral process. An email noting concerns does not necessarily constitute an evaluation request. To initiate the referral, send an unambiguous written statement requesting a special education evaluation for the purpose of determining whether your child is eligible for an IEP. The 120-day period starts only when you sign parental consent to evaluate. Send the request to the principal and the special education coordinator by email and keep your sent timestamp.

Schools also have independent Child Find obligations — the school is supposed to identify students who may need evaluation without waiting for a parent request. In practice, Child Find is inconsistently implemented in both DCPS and DC charter schools. If the school has been "monitoring" your child for several months without initiating a referral, a written request from you is the most reliable way to initiate the referral and document the concern.

Stage 2: Analysis of Existing Data (AED) — 30 Days

Within 30 calendar days of receiving your written request, the school must hold an Analysis of Existing Data (AED) meeting. The AED meeting brings together the parent and relevant school staff, including special- and general-education staff and an administrator, to review all data already available:

• Current grades and progress reports
• State assessment scores
• Teacher observations and behavioral records
• Previous evaluations or assessments
• Attendance and discipline records

The AED team determines two things:

1. Whether additional assessment is needed, and if so, in which areas
2. Whether the existing data is sufficient to make an eligibility determination without additional testing (rare, but possible for students with extensive prior evaluation histories)

If additional evaluation is needed, the school issues a Prior Written Notice (PWN) describing the proposed assessments and requests your written consent to evaluate. If you do not receive an AED meeting within 30 days of your written request, document the missed deadline and request the meeting in writing.

Stage 3: Evaluation and Eligibility — Within 120 Days from Consent

Once you sign consent, the 120-calendar-day DC period begins. The evaluation and eligibility stage includes:

• Complete all assessments in all areas of suspected disability
• Hold an eligibility determination meeting with the full IEP team

The eligibility meeting determines:

1. Whether your child qualifies under one of the 13 IDEA disability categories
2. Whether the disability adversely affects educational performance in a way requiring specially designed instruction

You are a required member of the eligibility team. The school must give you a copy of the evaluation reports before the meeting — not at the meeting, before it. Request them in advance.

The 120-day consent-to-services period is one of the most important deadlines in DC. If day 120 passes without an eligibility determination, a completed IEP, or services beginning, send an immediate written notice to the school noting the missed deadline and requesting a prompt status update. You can also file a state complaint with OSSE.

Stage 4: IEP Development and Implementation — Within the 120-Day Consent Period

If your child is found eligible, the school must develop the IEP and begin services within the 120-calendar-day period measured from signed parental consent. This phase includes:

• The IEP team meeting to write the annual goals, accommodations, services, and placement
• Your review of the draft IEP
• Your written consent for initial IEP services
• Services actually beginning

You do not have to accept the first IEP draft as written. You can request changes to goals, services, accommodations, or placement before signing. If the team disagrees with your proposed changes, they must issue a Prior Written Notice explaining the refusal and your right to dispute it.

Once you sign consent for services, the school must begin delivering them. The start of service delivery is the end of the 120-day window.

The Full DC Timeline at a Glance

What Happens at Charter Schools

Charter school LEAs follow the same 5-A DCMR timelines as DCPS — there is no separate charter school process. Each charter school must maintain its own special education coordinator, conduct or contract for evaluations, hold AED and eligibility meetings, and develop IEPs. The LEA designation means each charter school board is legally responsible for these timelines.

Charter schools are significantly more variable in their capacity to meet these requirements than DCPS. Small charter schools with part-time special education coordinators may struggle to hold timely AED meetings or complete the evaluation-to-services process within 120 days of consent. If your charter school's timeline is slipping, document the dates, send written reminders, and file an OSSE state complaint if deadlines are missed. The complaint process is free and OSSE must respond within 60 days.

Transferring Between Schools During the Process

If your child changes schools — from one DCPS school to another, or from a charter to DCPS — mid-evaluation, the timelines carry over. The receiving school does not get a fresh 30-day AED period or 120-day consent-to-services period — the clock that started at the prior school continues running. If the receiving school tries to restart the clock, that is a misunderstanding of DC law. Provide written documentation of the original request and consent dates and the days already elapsed.
