Elementary public, 20 minutes. You can always ask for one outside of official conference time.
Elementary middle, 20, but student led. They have their advisory teacher there and he/she helps facilitate, but the kids had to have filled out self-assessments for each class, the teachers each check "agree or disagree" and add comments to the self assessment sheets. They have examples of their work and the assessments in a portfolio and they have to talk about their strengths and "opportunities for growth." The grades area always available online and we can request individual meetings with their teachers in each subject as well. I thought it was a good compromise when they are old enough to move from class to class all day.
