What starts the evaluation clock
In most cases, the evaluation timeline starts when the school receives your written consent for the evaluation—not when you first raise concerns verbally.
Send the consent or request by email or letter and keep a copy with the date. If the school gives you an assessment plan or consent form, note when you signed and returned it.
Iowa timeline to know
Evaluation timelines in Iowa are set by state special education rules and published by Iowa DE. Do not rely on a blog's day count—confirm the exact deadline (and whether it uses school days or calendar days) in Iowa's procedural safeguards and on the official Iowa DE special education page linked below.

School days vs calendar days
Some states count only days school is in session; others use calendar days. Holidays and summer breaks can change when the deadline falls.
Ask your district special education office which counting method ${state.label} uses and how summer affects an open evaluation.
If the deadline passes
Write the district, note the consent date and missed deadline, and ask for a completion date in writing.
You can also review Iowa dispute options (state complaint, mediation, or due process) in the procedural safeguards if delays continue without a valid agreement.
Practical tips
- Calendar the consent date and the expected completion date the same day you sign.
- Ask whether the count uses school days or calendar days.
- Download Iowa's procedural safeguards PDF from Iowa DE or request a fresh copy from the school.
Common mistakes to avoid
- Relying on a verbal promise about timing without written consent on file.
- Assuming RTI or MTSS can indefinitely delay an evaluation you have requested in writing.
- Using another state's day count for your child's case.

Confirm timelines, forms, and filing steps on these official pages—rules can change.
Frequently asked questions
- Can the school delay evaluation because of RTI?
- Interventions can happen alongside evaluation, but they generally should not replace or endlessly postpone an evaluation once you have consented. Confirm Iowa practice in the safeguards and with Iowa DE guidance.
- What if I disagree with the evaluation results?
- You can ask for an Independent Educational Evaluation (IEE) and use dispute options described in your procedural safeguards. Get the refusal or proposal in Prior Written Notice.
