Totally agree. But, not to give school districts any slack, it is more difficult these days to determine "preferential seating," because the teachers tend to more around the room, teach from different locations/white boards, etc. As Lisa states above, you have to look at the individual student and what his/her needs are and then precisely define "preferential seating." You also have to ask if the onus is on the child to determine the best seating or the teacher. This depends on the child's age, awareness of their issues, and ability to self-advocate.
