Note that it asks the teacher to checkbox rankings of the student versus others the teacher has encountered in various aspects.
The ranking options are “no basis”, “below average”, “average”, “good (above average)”, “very good (well above average)”, “excellent (top 10%)”, “outstanding (top 5%)”, and “one of the top few encountered in my career”. There are 15 aspects plus “overall” to be ranked. This is in addition to a short written evaluation.
