As far as the open enrollment policy, it is not as easy. I just talked to someone from the CCISD administration about that couple weeks ago. Although CCISD has an open enrollment policy, each school make the decision if they want to be an open or closed campus and makes the final decision if they want to take on students not within their attendance boundary. A few of my friends just went through this last year, and all were denied and had to go to their home school. All intermediate and high schools are closed campus this year..and i was told that they may remain that way. So I would definitely not buy a house in one area and count on being able to enrol your child in a different school.
