We do something similar on 1126. We have student fill out a time-sheet each week, due on the Saturday at the end of each (Required to get lunch). This sheet includes the days the student attended and the hours they were there for each day. Students are also required to fill out what they did each day, and to get one of the mentors on their subteam to sign it, as well as rate the student on their performance each week.

The goal of this system is two fold:
One, to keep track of student hours. This system is largely based on the honor system, but if a mentor, while reviewing the form before signing, feels the hours are exaggerated, the student did not really WORK for those hours, or that the student is not being fully honest about their hours/days worked, appropriate measures are taken (generally, reducing the amount of hours that student is credited with for that day).

Two, to make our team as much like a real work environment as possible. Workers (students) are required to keep a (somewhat) detailed log of their work each week, and to get it approved by their supervisor (mentors). If not, the student is met with consequences (not being provided lunch for that Saturday until the time-sheet is completed and handed in).

For preseason and community service hours (which are also required by our team to travel) we use a basic sign in sheet.

Hope this helps! Feel free to ask if you have any questions.
