It really depends on your school district. We're in Loudoun and my K-grade DC gets preferential seating, speech therapy twice a week at the school, and one on one with a special ed teacher 15 minutes a day. We requested occupational therapy as well and it's pending right now. The district mainstreams everyone until they're 7yo and then you have an IEP re-look. I think only extreme cases end up at special ed and you have to agree to it. Dedicated aide at the mainstream school is a no go here, only at a special ed school. They just don't have the resources to provide this type of service at every school, which is completely understandable. I think the only way we got to an IEP quickly is the school district/our school realizing that we do a lot at home/private services on top of help we receive from school, so hopefully we will be a success story for them. Kids where parents can't afford private services, usually get sent to special ed school, but only extreme cases.
