> It is the purpose of public school educators to help their kids

Let's assume this statement is true, and public school educators are all saints who would never use the survey responses against their students in any way.

How do you know that only public school educators will have access to the information?

What if the surveys are sent back to the survey company for scanning, so that company now has the results as well? What if the information is stolen, leaked, or hacked, and posted on the Internet for anyone to read?

How do you know that some ambitious prosecutor who's looking for easy targets won't just find a lax judge who'll sign off on a subpoena of the survey results? School officials refusing to comply with a subpoena and going to jail to protect their students in this situation seems to be squarely in the realm of fantasy. Before you say something like "it is the purpose of prosecutors to serve the interests of justice, so they would never do crappy things," please read about Aaron Swartz. And really, by some definition, enforcing anti-drug laws in the most cost-effective manner may be an optimal use of a prosecutor's time.
