Admin often wants to look at attendance for specific grades and departments, especially when certain grades/depts have more problems taking attendance. Also, although the school is divided into levels, practically admin is mostly split along departmental lines, so the head of one dept will want to deal with class attendance for classes of all school levels in their department only.

Adding these filters as well as a search bar (like other SKY lists in the system) would really enhance Class Attendance's usefulness.
