My school does not have a specific AUP, but covers rules for computer and electronic throughout the handbook. There is a code of conduct for the students as a whole, but no section specifically for computers.
Due to a lack of an AUP there is no definition section. I think the lack of definitions stems from most of our students being fairly technologically adept. I would say at least 90% of them have smart phones and/or a laptop that they bring to school. They regularly use their own laptops in class.
There is nothing about when students can use computers. Most of our students have their own computers, which they prefer to use over the slower school ones.
The acceptable use section is short, with only a single sentence asking that the students use their personal computer equipment for educational uses. The unacceptable use is also a short section with guidelines that specify students are not to be gaming, watching movies, or looking at inappropriate materials during class. The inappropriate material applies for time that is not in class as well. Phones and gaming equipment is not to be used at all during the school day, while laptops are permitted and music is at the teacher’s permission.
The school does not have a comprehensive AUP, as the code of conduct extends to all areas of interaction. There are few disciplinary problems beyond the using a cell phone during a class or looking at youku or youtube on their laptop. I feel if the school had more of an issue with these things an AUP would be developed.
