Hello Adam,

I suspect you are exploring this for 508 compliance so please don't
consider this any sort of official opinion.  That said, I have a couple
comments.

Your present design doesn't strike me as all that bad and is quite common
from the perspective of what a user is used to.  Most check boxes on web
pages appear before the text of the check box.  I can actually make a case
that this is a better design as the appearance of the check box after the
prompt is likely to seem more confusing by comparison.

With JAWS in the Virtual PC mode, the default for web content, the user
would experience a check box, arrow down once and then the text.  If the
user presses enter (this is how you set focus to a check box or other form
control from the VPC mode) on the check box, the associated label text
will be read along with the fact that it is a check box.

Window-Eyes takes the label text and explicitly associates it with the
control in what it calls the MSAA mode.  This means that label location is
not critical for Window-Eyes because the user will experience the label
text on the same line as the control as well as in the original location.

Home Page Reader behavior is similar to JAWS.

All three of these screen readers use what I'll term
a buffered reading mode.  By that I mean they load the web content and
reformat into a decolumnized view among other items.

There's also the possibility of using a title tag directly on the input
control.  At present Window-Eyes is the only product I know will use this
information but I believe other products will in the future.  Nor it it
clear to me how Window-Eyes and other products will handle title and label
text being present for the same control.  I believe Window-Eyes defaults
to label text in such cases at present.

This makes perfect sense to me - why present someone with a checkbox before telling them what it's for? However, a colleague prefers the layout of the draft form as it is - it's visually closer to most paper-based or web-based forms she's familiar with.
