He tends to be on the lower side of average for articulation, but keeping up. His grammar seems delayed to me, but I'm used to a highly verbal PG child and his teacher and SLP seem to think it's normal. He just has a few problems with unusual tense constructions. He can have a complex conversation with us; he gets fewer opportunities to do so with his teacher so I can't tell if she would see anything unusual in his speech. I think I will ask her to try having a longer conversation with him at some point to get some feedback. When I picked him up after his pre-kindergarten screening at the school, the tester came over to me to tell me how impressed she was at his verbal ability (his vocabulary and knowledge of sight words). I don't think that most people actually take the time to have a longer conversation, though, and that might make issues more obvious.
