I've been screaming this for years: there was never a rational reason not to buy off-the-shelf solutions. This problem is identical to those faced by thousands, even millions, of other organizations. The solution has been developed and refined for decades. Why should a single school district try to reinvent the wheel from scratch? There must have been bribes and kickbacks involved, as there is no other explanation for them choosing this path over utilizing existing solutions. It's astounding that people haven't been imprisoned for this yet.
