FYI, email from ETS today:
Our Audiology Study Guide for 0341 will be available in the next few days. If you don't see it posted my EOD tomorrow, check the website on Monday or Tuesday. The link to that would be found on the test prep page for the Audiology test http://www.ets.org/praxis/prepare/materials/0341. The study guide should appear below the Related Test Prep heading.
