Appendix G has the list of what IS required on the Special Symbols page – everything else is not required 🙂 A transcriber should consider the reader though – as, for instance, the asterisk is not listed as one of the required symbols but might not be familiar to the reader. It’s not REQUIRED but it might be helpful for a reader. Please note that if you are taking a certification test, what is not required should not be listed.
