If he does have speech needs, he may be able to get early intervention. My daughter was 3 and was in an intergrated pre-school. She was considered a "model" student which meant only that she was on target. It was by lottery that she got in. The class was made up of 12 children with half being model and half being children with needs, whether physical or speech, mild to moderate needs. My child went 4 days a week for a fee and the children who needed services went free 1 to 4 days, depending on their need and they got free transportation. It was a wonderful program. Those children would have therapy, speech or PT, but they would also take the children without need with them to model. It was a great ratio per child and my child was automatically allowed to go the following year. This was through my town. She also ended up being in the intergrated kindergarden class where there was also a great teacher:student ratio. Many of those children just needed a little extra but caught up very quickly. It is worth having him evaluated. I would also make sure you have his hearing checked to make sure it isn't medical. Has he had a lot of ear infections?
