<p>In terms of “what I wish we had known” when my son was a junior, find out about any conferences or festivals in your area that might have auditions and college representatives. My son benefited enormously from attending the Virginia Theatre Association conference this October (which I only learned about here on CC, by the way) and I wish he had participated in some Thespian festivals and the SETC (South Eastern Theatre Conference) during his junior year. Depending on where you live, there may be more or fewer opportunities. You can learn a LOT this way.</p>
