Ok, I've got the data sorted on the highest ranked schools in the Los Angeles Unified School District. I was going to post the table, but I can't figure out how to do it. If you want to create your own spreadsheet to rank the schools look at the following website:

As soon as I figure out which city has the three highest elementary, middle and high schools I will let you know.
