I am an Oro Valley resident as well as a father of two (3 year old boy and 6 year old girl) We moved to Oro Valley for the school systems. The Amphitheater school district consistently achieves higher overall test scores than the other school districts in the Tucson area. The neighborhoods are very family oriented with lots of parks, jogging and biking trails. There are many schools within neighborhoods so commuting back and forth is short and easy for the kids as well as parents.
Oro Valley is also the city that consistently has the lowest crime rate in Arizona, so many residents, young or elderly, feel more safe when out and about. I can go on an on about this great town, but we don't have the space for it. Please let me know if you have any other questions.
