The further out you move the less strict/challenging the school (is what I have noticed as well as some friends) in lesser known districts. Denton ISD isn't too bad. However, I have two friends that live in Aubrey and they do not like the school district due to not as challenging, bullies...etc. I do believe that you need to thoroughly check out the school district by seeking out reviews online. Just remember there will always be positive vs negative for all locations.
As a personal experience...my husband and me moved from Plano to Little Elm for our daughter's last year of high school. The school stated it was exemplary but by their standards they were...by ours not so much. Our daughter was highly commended on all her state tests; Little Elm was happy to have her to add to their roster. Plano Senior High School said they did not want to lose such an excellent student and offered my daughter the option to stay for her senior year. She chose not to make the drive and regretted it. The Little Elm high school did not require much of her, at Plano her final year she would have had to take 7 classes in Little Elm only 2 but she had to fill in two electives to meet their 4 classes otherwise they stated by Little Elm standards she would have been graduated. We moved out of Little Elm (denton county) and came back to collin county. We we're glad that we only rented to test the waters.
Every parent has their own set of standards, just as school districts do. It is up to you to weigh the negatives vs. positives for your children. Do your research online, go in person to inquire about curriculum...ask them questions. I am sure you will make the best decision for you and your family :)
