title: Are CAPTCHAs Accessible?
body: <p>I am writing a website in my spare time for an educational facility and from what I've read on the statistics of this place they seem to have many disabled students studying there. Simply put, I'm setting up an account system where students can log in and receive basic information about their courses, allowing them to comment on their courses and how they felt the course represented them.</p>
  
  <p>I'm not too sure on the legal implications of this, but I am pretty sure that if you are working for an educational body then it is a legal requirement for your website to be accessible to those with disabilities. The code is perfectly fine, apart from one problem; the CAPTCHA.</p>
  
  <p>As far as I am aware most CAPTCHAs are image-based, which will make those using screen readers struggle. On top of that, ones that support sound readings may not work too well as in many buildings there are no speakers for the user to listen to the recording. I could always use a small field asking a user to put two numbers together but those are often far too easy for bots to attack.</p>
  
  <p>I may be making a mountain out of a molehill but it's still an interesting question for those that have an interest in accessibility. Does anyone know of a good way to keep spammers out and users in within this environment?</p>
