If you're interested in schools I recommend you check
www.greatschools.net. They provide a consolidated source of information including their rating, the state rating, average math class size, TAKS results for 4th 8th and 10th grades, the teacher average years of experience and a percentage of new teachers, attendance rates, percentages of free and reduced lunches and limited English proficiency, and an ethnic breakdown on the students.
They also offer parents opinions. Which can be a very mixed bag, both because it's typically on the very happy or very upset parents that post, and because their experiences are individual and not an overall representation of the school.
