In addition to hours of attendance, we measure quality: Every student gets two "performance reviews", either of which could prevent them from traveling.

The first review is in week 2, and here we focus on opportunities for improvement (if any), or just reaffirm they are on the right path. The second review in week 5 checks if they fixed any challenges they were having or not.

Reviews are carried out by the student team leader with a mentor present. We have a rubric (a kind of checklist) with specific examples of poor, acceptable and excellent behaviors. It's not very subjective, but that can't be eliminated entirely.

Virtually every student with a 'need improvement' review in week 2 cleans up their act by week 5. Some do drop off the team though.
