Live Cycle automatically tags your fields and helps you set your tab order. Like, I said when I use the screen reader tool everything works the way it was designed in Live cycle in terms of the reading order (but it ignores the image).
The only issue I have is that the accessibility tool checker in acrobat pro keeps flagging one item, the top logo and won't allow me to enter alt text. As a workaround I included the text for the logo (institution name) on the page. I would like to edit the alt text either in live cycle or acrobat pro, or any program that will let me do it.
I worked on another document in Indesign and then brought it into live cycle to add some fillable fields with tags. The file has a large image in the background. When brought that file into acrobat pro and it actually allowed me to edit the alt text for the image. It seems like a really long way to get this end result, so I would appreciate a simpler solution that could address the alt text issue.
