About this calculator

This free tool turns each state's special education timeline rules into dates. It is built and maintained independently. It is not affiliated with any school district or state education agency.

How the dates are calculated

• Calendar days count every day, including weekends and holidays.
• School days count weekdays inside the school year that are not on the closure list you entered.
• The day consent is received is day 0. The deadline is the last day the rule allows.
• Annual review and reevaluation dates are counted from the IEP date you enter, or from the latest allowed IEP date if you leave it blank.

Limits

Results are estimates. They are only as accurate as the school calendar you enter, and they do not cover every exception in the regulations (for example, a student who changes districts during an evaluation). This is not legal advice. Confirm deadlines with your district, your state's parent training center, or an advocate.
