The school is asking your permission to evaluate your child, or you have asked the school to evaluate. Nothing has been decided; an evaluation is information, and it belongs to you as much as to the school. Under Child Find, every Washington district must look for children who may need extra support, so the letter means the system is doing its job of looking. Saying yes does not place your child in special education; that takes another decision, with you at the table. Once the school has written permission, Washington law gives it 35 school days to finish the evaluation (WAC 392-172A). You can ask what the evaluation includes, request a bilingual evaluation or an interpreter during testing, bring anyone you want to the results meeting, and take documents home before signing.
