If the school offers separate conferences to divorced parents, can it exclude one biological parent from one of the conferences? Assume there is no legal reason (e.g. EPO) why the parent cannot be present at both.
Concerns related to having two conferences where one parent might disagree with this process include:
1) Information about the child's education might get missed, parents will have different questions and it is unrealistic to expect the teachers to keep detailed notes and share all that was discussed
2) One parent might say (or find it easier to say) uncomplimentary things about the other (credit to Catija in the comments for suggesting this reason)
3) Having two conferences is a burden for teachers, and even if offered by the school, might not be appreciated esp. if the teacher has to take personal time out to accommodate the parents
4) Having two conferences can confuse the child (e.g. why is this happening now differently to the past) or demonstrate that two parents cannot set aside their differences for the short duration of the conference
5) If the child can only be present at one of the conferences due to scheduling issues, then the excluded parent might prefer to be at the conference where the child is present
