I don't teach Special Education so I don't know about SETS
    specifically, but I do know we've been pretty dissatisfied with
    STI in terms of posting grades and the incompetence of the woman
    sent to conduct a 3-hr "training" session, and lack of
    documentation provided. Not to mention the fact that it has
    mysteriously "lost" entire sets of grades -- luckily I had made a
    hard copy the week before, so I just had to re-post the grades
    (and also I had evidence for those in our office that the program
    HAD lost the grades and that I had not simply made a mistake in
    posting them).Not exactly what you asked, I know, but it seemed relevant.
