Because ratings change from year to year, and because there are numerous elementary schools, the best way to keep up-to-date on school rankings is to visit their websites where the very latest information is posted. You'll also find school calendars and other useful information.
For NBISD their website is: http://www.nbisd.org ;
For Comal ISD their website is: http://www.comalisd.org.
If you have specific elementary schools you'd like to compare, just let me know and I'll be glad to help.

Go tour them! You will get the most out of that. Please note that NB school district really tries to balance the mix at the schools so the boundaries are all messed up. You could end up going to school 30 min away from the house.
I have a brochure that shows all of the school ratings and district information from the 2010-2011 school year (the 2011-2012 info isn't out yet I don't think). I can mail it to you if you'd like. You can email me at AjaSellsNB@gmail.com if you'd like me to send it out to you.
Have a good one!
