filtering, thanks Craig Lyndes) on loan for use outside of school.
This is usually for field trips, etc but did once however include semester long home use where a student signed up for an in-person class, but ended up in an online class.
The student had a computer at home, but no internet access, and could not stay after school to work on assignments, etc
Since we felt that was a situation the school created, and couldn't find any other solution for, we covered the cost.
We are not in a Comcast region, so that option doesn't apply for us.
Prior to promoting access at home, I would think access on school buses would come up more, I know at least a few schools have done that here (and more around the country).
