This is a public elementary school. He is in a preschool program that is for 'high risk' children. Because his mom didn't graduate from highschool and we are divorced he qualified for this program (he is 4). We thought it was best to get him in school, but we make to much for him to go to head start and I wasn't going to shell out 700-1700 for a private preschool! The home visit is so that the teacher can see how the child reacts at home with the parent and the teacher and parent can discuss what the program is like and any concerns the parent may have about the child.
No, it is not mandatory to meet at your house. The teacher can meet you somewhere else like a restaurant if you prefer them not to come to your house. The one on one time is to help your child, they are not ridiculing your housing situation.
The visit went well. She was impressed with his knowledge of language and it was a real laid back situation. I think this will be good for my son this year!
