School Website Accessibility

My school's website is fairly accessible.  The Wave site only found three errors and they were all the same type of error; a "form label" was missing.  It seems like a text reader would easily be able to read through the site and the only video on the site doesn't have audio so it would still be accessible for the visually impaired.  The site is very clear and straight forward making it easy for a novice internet user to navigate.  I can also access the site from my smart phone and the site is accessible from older computers (like the ones we have at school) as well, making it robust.  I'm waiting for our site administrator to get back to me about any accessibility guidelines she has to use when putting the site together.
