Does a school have the right to interrogate a student without parental notification?

Question Details:

School interrogated my 12 year old daughter. They accused her of being on drugs (of which none of this is true), shined flashlights in her eyes to determine dilation, and put her in ISS. I was not notified either by phone or otherwise and now it's all over school. Her cousin, also 12 years old, was done the same way as her. Are they allowed to do this? Important Notice
