I don't think they've done CELF. It was mentioned a few times, but I don't think it was ever actually done.

They did tell us once his expressive language was poor and he needed a special group to learn how to express himself with his peers. But I think that was based on a less formal assessment, and when we pressed, the SLP said the only thing he was low on was code switching from formal to casual speech--he used formal speech too much, which really didn't seem an issue to me.
