We use Nutrikids since no one wanted to pay the $ to use the IC tools.
Ditto what they use for SpEd; that involved the timing of a vendor contract
that renews in the middle of the school year, and trying to get the data out
of there to put it into IC. They weren't cooperative, and it was decided that
it wasn't worth it.
The library systems are still what they already were; that was about change
and nobody liking it.
Same with the financial piece and student fees; our network guy and I lobbied
hard to use it, and the Business Manager at the time didn't want anything outside
of her direct in-office control, so that was out.
Resistance and $ have been the stumbling blocks here.
