One of the things I have noticed going from preschool to school is that the relationship with the teacher is much more superficial. My son's strongest test was problem solving (AE of 16+ at 5.8) which really only shows if you give him hard problems to solve or have an depth conversation. The preschool teachers had the time and inclination to do that as they are interested in the child developing. School teachers have less time and are more interested in the child conforming. That's what is seems like anyway.
