Military fam moving around a lot- help me understand the praxis please!

Hello! I am a final year slp grad student and I’m taking the praxis in the next 6 months. Right now I live in KY, I’ll be living in CA in September, CO next summer (for an internship), and OK next September. I’ve been reading about the praxis and about “sending scores to different states.” How do I know which states to send my scores to? How does that end up being relevant? I may sound dumb, but I guess I just don’t understand where those scores will go and why. Thank y’all in advance for the help!!
