Actually I think it's a perfectly appropriate use of facial recognition in this case. Firstly, the school district already has a picture of every child at the school. Second, they already track the child (manually) at all times throughout the day. So, they are not collecting any more information than they already had, nor are they collecting any more information than is legally required (attendance tracking is likely to be legally mandated) The end result is the same exact data exposure / privacy risk that they started with, and more classroom hours to actually teach instead of taking attendance. The classroom setting is a particularly good example of the narrow use case when facial recognition is acceptable. Unlike, for example, in a retail establishment, where a casual customer who browses the store but does not buy anything would otherwise remain anonymous. Quite the contrary, you do not want anyone in the classroom who is anonymous.
