Parent teacher conferences are held each year they are normally done at the beginning of the year because by now the teacher would now have an idea of each student's strengths and weaknesses. Schools understand that parents have a lot to deal with and so to make parent teacher conferences more convenient.
Things discussed at these meetings include the teachers study plan for the year and the child's performance. Behavior, attendance, class work performance, and students attention span in class are some of the things that each teaching system is expected to describe about each student.
If the child is a bully or is a disturbance for other students, the teachers have to discuss what they can do to make the classroom more conducive for all students.Usually when a child is behaving badly at school something is wrong at home. At parent teacher conferences teachers get the opportunity to find out what the situation is like at home.
