Yes, it's a public school, gasp gasp, but it's one of the best public schools in the Tempe High School District.
If you're looking for a school that isn't as dangerous as let's say, McClintock or Mountain Point, Desert Vista is for you.
If your kid is studious and competitive and all around smart and you want him/her to stay that way, Desert Vista is for you.
Sports are also a highlight at DVHS; no one joins a team unless they know what they're doing, and more than likely, everyone on the team works together. It's a great environment academically and athletically.
