? Letter to the SD to request evaluation


Warrior Mom since 2007
I am getting ready to send a letter to the SD to request a full initial evaluation of my 5 year old son (entering Kindergarten). Could someone please point me in the right direction about what specifically I need to mention in the letter and what I need to know about timelines, etc. I know it has been discussed before and many of you have said there is info in the archives, I just need some help finding what I need. Also, do I send the letter to the director of Special Education for the district, and not to the principal of his specific school? Thanks!
