Hello E.-My twins are 23 months old so not in school yet but I did teach for LISD prior to having them so I consider myself just knowledgeable enough to get myself into trouble. I'm kidding.
I'm attaching a link for LISD schools and you can check them all out but the two schools you might want to look into are Old Settlers Elementary andMcKamy Middle School which are both EXEMPLARY schools. The high schools you would feed into are either Flower Mound or Marcus and both are Recognized schools. I live near Prairie Trail Elementary which is also Exemplary and Lamar Middle School which is Recognized. My kiddos would attend Marcus High School after that.

Good luck to you!
