Child diagnosis

My son is 6 and currently in kindergarten and we had a parent teacher conference after he had his school hearing test to go over things. They talked to us about issues in school with him understanding things said to him and the person who administered the hearing test sent us a referral to have him checked for apd. From research it doesn’t seem like a disorder to scare us for him life but one that worries us for the future. I just want to get an idea of what life is like for everyone and things we can do to help him if it ends up being apd.
