If a teacher is not scheduled for the first term of a section, that teacher cannot enter course recommendations. For example, if a class is year long with terms 1 and 2, if the teacher is only scheduled for term 2, the teacher is not able to enter recommendations. As a workaround, we temporarily schedule the teacher for term 1 and later remove them when the recommendation period has ended (and we have to be sure to reschedule them for term 2 when doing that, so it is a bit clunky). It is important to correctly reflect the teachers because the school has report cards set to print all teachers.
