At my dc's school, only the students in the School of Logic (6-8) grades do these. At first, I was a bit suspicious and thought it a waste of time. But then I went to them, actually just yesterday, and I was quite impressed. They had to dress in Sunday best and act professional. They had a very impressive portfolio they went through with me, goals they had made for each subject, sample work, report card, etc. The teacher's were there in the room to answer any questions. After the conferences with my kids, I went and talked to the teacher's about behavior and socialization type issues.
