Priority levels

Accessibility checking is assigned to three levels of priority are :

  • Priority 1 : Are those points that a web developer has to comply because, otherwise, certain groups of users could not access the Web site information.
  • Priority 2 : Are those points that a web developer should comply because, if it were not so , it would be very difficult to access the information for certain groups of users.
  • Priority 3 : Are those points that a web developer should comply because, otherwise, some users may experience some difficulties in accessing information.

Conformance levels

Based on previous checkpoints there are three different levels of conformity::

  • Conformance Level " A" : All checkpoints of priority 1 are satisfied.
  • Conformance Level " Double-A" : All Priority checkpoints 1 and 2 are satisfied .
