NCLB testing (aka FCAT) results in Google spreadsheet form. Broward County schools ordered by percentage of students qualifying for free and reduced lunch.
The "poverty percentage" column is ordered from lowest to highest to highlight the test results in low poverty communities. All schools have been included regardless of student age. Without working any further, it appears to me that minority percentage may be a stronger indicator but if you're high in both columns, an A or B looks really hard to do.
I might order it differently from time to time so don't be surprised. It should not be hard to tell.
