I think the things that you don't like about the school you are at are an important consideration. What is it---besides school ratings--that is different at the other school. I am a teacher, and I do understand the importance of ratings, but they are not everything. Those ratings are based on a lot of different criteria, and you really have to look at the individual numbers to see if the rating is really accurate. The way that the rating system works just one student of a particular ethnicity or socioeconomic status passing or failing a test can make a difference in the school's rating--I know that sounds impossible, but it is true. Also, being close to home can be a big bonus.
On the flip side, atmosphere can mean a lot. Is your daughter happy in the current school? If your daughter is miserable it will have an impact on her future relationship with school. Does she have lots of friends there--do most of the neighborhood kids go there? Good schools are very important, but I believe that they become more important when it comes to middle and high school. The long-term impact is much greater at that level.
I know that this was kind of rambling, but there is definitely no right answer to this question. You just have to take all the factors into consideration and do what is right for your family. I do think that whatever choice you make, it would be best if you stick with it for the rest of elementary.
