I recently checked out one of my students prior to a solo circuit session. Checkout was very brief since he was perfectly competent. I de-briefed him that his circuits were fine, but he could do with making them a little smaller, and sent him on his merry way.
Half an hour later I had a call from ATC, asking me to have a word with my student when he got back. He was apparently flying his circuits too tight, and had cut up a student from another school on the airport who was flying cross-country circuits.
