If a teacher/headteacher calls the parents of just one pupil in to the school for a meeting, it is usually because the child has a problem or is in trouble. I don't think we have a word for that. The parents would just say that they've been called in for a meeting with the school about their child.
Note: please make your thread titles more relevant to the thread. A good title would have been "Homeroom teacher has a meeting with a pupil's parents" or something similar.
Please also note that we say "What do you call this?" or "How do you say this [in English?"
