Test scores, teacher evaluation and truancy

There is consensus that students who are not in school cannot learn; that even the best teachers cannot teach students who are not there.

Since teachers have no control over whether students are truant, how can they be held accountable for truancy (by means of poor test performance by chronically absent students)?

For that matter, how can they be held accountable for the test performance of chronically disruptive students?  Or for that matter, the test performance of the students whose learning those students disrupt?
