Student records should contain both positives and negatives. What would be the point of them otherwise? However, on one occasion I have to hold my hand up. We've all had them. Students of limited ability who rarely appear. We were doing circuits. It was like the student had never had any flying instruction before. Shockingly bad. I was exasperated. All I could enter on their student record was "Clueless. Marginally less so by end." Not very constructive but fair none the less. The comment has become part of my flying club's folklore. Sometimes you have to say it as it is.
