I don't know the cost of the edline system and probably don't want to know. It was undoubtedly a sizable investment and there are teachers and schools that do not make full use of it. As it stands, it is a prop that the district can point to and claim that parents are aware and informed of their child's progress.
Unfortunately, some teachers don't use edline at all or only update it once or twice a quarter. If it isn't going to be used universally and regularly then save money and dump the system.
