A talk in the hallway or a phone call does not start the school's clock. There is no dated paper to point to later. A written, dated letter shows what you asked for, when you asked, and what worried you. That is what starts the process in a way you can prove.
You need no special words and no form from the school. A short letter in plain words is enough, as long as it clearly asks the school to test your child.
Keep it to one page. Clear, dated, and specific is stronger than long.
There is no single national clock for this first step. Your state sets how fast the school must answer, and states count days in different ways:
In another state, ask the school in writing which rule applies and what date it counts as the deadline.
[Your name, address, phone, and email. Today's date.]
Dear [Principal or Special Education Director],
I am writing to request an evaluation of my child, [full name], born [date of birth], in [grade] at [school name]. I am concerned about [name the areas, for example reading, paying attention, and finishing written work]. I have noticed [one or two short examples, with dates].
Please let me know in writing what happens next, and please send me the consent form to sign if you agree to evaluate. If you decide not to evaluate, please tell me that decision and the reasons in writing. Thank you. [Your signature and printed name], parent of [child's full name].
Send the letter in a way that proves the school received it. Hand-deliver it and ask for a date-stamped copy. Or email it and keep the sent email. Or use certified mail and keep the tracking receipt. Keep your copy, proof, and any reply in one folder, in date order. If the school answers by phone, follow up the same day with a short email confirming what was said. That creates the paper the call did not.
