School ratings are F-ing confusing

You suck! No, wait. You’re the best!

Dozens of city schools that were given low marks by the state in late August were given high grades by the city this week — and vice versa, The Post has found.

The conflicting messages sent parents’ heads spinning at schools such as Ella Baker elementary school on the Upper East Side — which was highlighted by the state as one of the city’s 39 best elementary and middle schools, but was given a lowly C grade by the city.

“If it’s truly a C school, I’d strongly consider putting my kids somewhere else. But if it’s in the top 5 percent, it’s good, right?” said David Rodriguez, who has three kids enrolled at the school.

Officials said one obvious difference between the ratings is that the city’s grades include data from the 2011-12 school year, while the state Education Department’s data run only through 2010-11.

The city’s system also gives more weight to progress and accounts for differing demographics.

Of the 39 city middle and elementary schools the state rated at the top, eight got C grades and 17 got B’s from the city. Of the 61 schools the state said were among the worst-performing 5 percent, 20 were given B grades by the city and one was given an A.
