I would suggest comparing Fort Worth ISD with other local districts such as Keller ISD, Northwest ISD, White Settlement ISD, Birdville ISD, Saginaw ISD, and other surrounding areas in which you might wish to live. FWISD is what it is, although if schools are important to you, I would compare it to others first. Are the highest in FWISD higher than the lowest in adjacent districts?
I believe te rankings are posted on the district site. Otherwise, hunt just a little more. You will find these answers and more.
