"I don't get what the difference is between ASHA's Evidence Maps, speechBITE, and The Informed SLP..."

Ah—an excellent question!

This one came in a couple weeks ago, and the first thing I did was reach out to folks at ASHA and speechBITE so we could write a collaborative response for you, together! It didn’t fit very well in a standard narrow blog post, so click on the image below, and you’ll be redirected to a full page explaining the three.
 
Cheers, #ebpSLPs!
