The Wisconsin IEP Evaluation Process: Timelines, Forms, and How to Request One

Your child is struggling. The teacher says she is "monitoring" the situation. The school mentions something called Response to Intervention. Another quarter goes by with no formal action. You are wondering whether there is a process you can trigger that actually has deadlines — something the school cannot just watch slide.

There is. Here is how it works in Wisconsin.

Your Right to Request a Special Education Evaluation

Any parent can submit a written request for a special education evaluation at any time. You do not need the teacher's blessing, a doctor's diagnosis, or the school's agreement that your child is struggling enough. The right to request an evaluation is unconditional under IDEA and Wisconsin's Chapter 115.

Write a brief letter or email to the school principal and special education director stating:

• Your child's name and current grade
• Your concern that your child may have a disability affecting educational performance
• A formal request for a comprehensive special education evaluation under Chapter 115 and IDEA
• The date you are submitting the request

Keep a copy. Note the date it was delivered or sent. The 15-business-day clock starts from the date the district receives your written request.

The 15-Business-Day Timeline

After receiving your written referral, the district has 15 business days to convene the IEP team to review existing data. At that meeting, the team makes one of two decisions:

Option A: Additional evaluation is needed. The district sends you a formal written notice requesting your consent to conduct a comprehensive evaluation. This notice must describe the assessments proposed, why each is necessary, and the potential impact on your child.

Option B: Existing data is sufficient. The district sends you a formal written notice explaining that it believes no additional evaluation is necessary and why, and informing you of your right to request an evaluation anyway.

If you receive Option B and you disagree, you can demand an evaluation. The district cannot simply refuse all evaluation requests — it can disagree with your conclusion, but it must then follow the consent-or-deny process and document its reasoning.

One thing to know: districts cannot use participation in a Multi-Level System of Supports (MLSS) or Response to Intervention (RtI) framework to delay or deny your evaluation request. This is explicitly stated in federal guidance and reinforced by Wisconsin DPI. If your child is in Tier 2 or Tier 3 interventions and the school tells you it needs to "wait and see how interventions go" before evaluating, that is not a legal basis for delay. The 15-business-day clock still applies.

The 60-Calendar-Day Evaluation Window

Once you sign the consent to evaluate, the district has 60 calendar days to:

1. Complete all assessments
2. Convene an IEP team meeting
3. Present the evaluation results and determine eligibility

Sixty calendar days includes weekends and holidays. This is strict. Exceptions are narrow: student transfers mid-evaluation, parent repeatedly fails to make the child available for testing, or a mutual written agreement extends the timeline specifically for a Specific Learning Disability evaluation.

During the 60 days, the evaluation must be comprehensive — it cannot be limited to the area the school suspects is the primary concern. If your child is referred for reading difficulties but also displays signs of attention deficits, behavioral challenges, or communication differences, the evaluation must be broad enough to assess all areas of suspected disability.

What a Comprehensive Evaluation Includes in Wisconsin

Wisconsin's special education evaluation is not a single test. Depending on the suspected disability category, it typically includes:

• Cognitive/intellectual assessment — Overall ability and processing profiles
• Academic achievement — Reading, writing, and math performance across multiple measures
• Behavioral observations — Systematic observation in academic and non-academic settings
• Parent input — A structured interview or questionnaire documenting developmental history and current functioning at home
• Teacher input — Reports on academic performance, adaptive behavior, and classroom functioning
• Domain-specific assessments — Speech-language evaluation for communication concerns, occupational therapy assessment for fine motor or sensory needs, etc.

The evaluation team uses the results to complete the appropriate Wisconsin DPI evaluation form. For most disability categories, this is Form ER-1. For Specific Learning Disability, it is Form ER-2-A. For Autism, Form ER-1-AUT. These forms structure how the findings connect to Wisconsin's PI 11 eligibility criteria.

A clinical medical diagnosis is relevant data but not dispositive. The evaluation team must document educational impact — how the condition affects the child's ability to participate in and progress through the general education curriculum — using educational assessment data. A child with a documented ADHD diagnosis who is performing at grade level and keeping pace with peers may not meet the IEP eligibility threshold under PI 11, even though they have a real disability.

The Eligibility Meeting and What Happens Next

After the evaluation is complete, the IEP team meets to review the findings and determine whether the student meets the eligibility criteria for one of the 13 disability categories under PI 11 and has a demonstrated need for specially designed instruction.

If the team determines the student is eligible:

• The district has 30 calendar days from the eligibility determination to develop the IEP and make a formal placement offer
• You receive Prior Written Notice (Form M-1) describing the proposed placement and services
• Services cannot begin until you consent

If the team determines the student is not eligible:

• The district issues a notice of ineligibility documenting the reasons
• You can disagree and request an Independent Educational Evaluation at public expense
• You can file a state complaint with the DPI if you believe the evaluation was procedurally deficient
• You can request a due process hearing

The Evaluation Timelines at a Glance

These are Wisconsin-specific timelines governed by PI 11. They are not suggestions. If the district misses them, that is a violation you can raise through a DPI state complaint.

The Wisconsin IEP & 504 Blueprint walks through the evaluation request process with a step-by-step checklist, sample language for your written referral letter, and a guide to what to look for in the evaluation report to verify the district met its legal obligations under PI 11.
