I expect students to be hassled about search refusals due to the newness of this law, but hopefully school officials will respect students' right to privacy as reflected in this law. I find this respect unlikely, unfortunately. I also believe schools will try to balk this law and overturn it as it applies to them. With the way the courts have gone, I foresee them wiggling out of this law in the school setting. I hope I am wrong.
This law should make for some fireworks. Hopefully it will lessen the almost continuous intrusions into students' phones and personal data, which is rather common these days.
