I'm not sure about this (at all), but the feds do some type of yearly school evaluations (called AYP) in accordance with the No Child Left Behind (NCLB) Act. If I am reading the new report correctly, I think Bridgeport High School may have taken another hit. The above is a screen shot of a huge pdf file for all schools.
But I've received no confirmation of this. Also, I think its possible the feds consider the TAKS results which could explain this ranking.
