Hi there!

To answer your question, I'm afraid that the Praxis exam is not the correct test for the Indiana Instructional License. According to this news article and the Indiana department of education, Indiana switched from the ETS Praxis test in 2014 to another test.

Additionally, here's a video which seems to give an overview of the Indiana Educator License materials: https://www.youtube.com/watch?v=21QNUaKuVzE&feature=youtu.be

I hope this answered your question! If there's anything else that I can help you with, please let me know.
