I had the opposite experience (at Richardson ISD in Texas).  I spent my entire senior year being 18, and aside from a few nice teachers who let me sign my own syllabi, they just completely ignored the fact that I was an adult.  They made me have my mom sign things and excuse me from class (although to be fair, in this state adults enrolled in K-12 classes are still required by law to attend).  I had to get a parent signature in order to get a non-zero grade on a research paper.  I even had my choir director tell me that I &quot;don&#x27;t get a bunch of rights&quot; when I had the gall to ask if I could consent to my own medical care for trips.<p>I also heard a couple of stories of adult students who didn&#x27;t live with their parents being tricked into signing &quot;affidavits of residency&quot; that actually took away their rights and gave them a guardian until their graduation.  If this is true, then I have no clue how it could possibly be legal.  I&#x27;ve found nothing online about that kind of thing.<p>And all of this while we have a law on the books <i>requiring</i> adult students to exercise parental rights for themselves:  <a href="http:&#x2F;&#x2F;www.statutes.legis.state.tx.us&#x2F;Docs&#x2F;ED&#x2F;htm&#x2F;ED.26.htm#26.002" rel="nofollow">http:&#x2F;&#x2F;www.statutes.legis.state.tx.us&#x2F;Docs&#x2F;ED&#x2F;htm&#x2F;ED.26.htm#...</a>
