Low Voltage Cabling Code Help

[Hagelund]

This installation was completed recently by our local school district IT department, and sadly it seems to be typical work for them. Will someone please tell me that there is a code I can reference somewhere that I can use to stop installs from looking like this in the future?

I wonder how much they pay the beaver to gnaw those holes in the wall?
