It appears that the State of Washington only offers auditing opportunities for Senior Citizens, in other words sit in on classes for free or a small fee of 5 dollars, although this would not be credited and you can not participate in test taking and other assignments.  A great opportunity to fulfill academic curiosities, but would not include receiving credits for those classes.    We will be continuing to seek out more information on the issue.
