With the vast majority of New York City schools receiving A's and B's on the progress reports released this week, Education Department officials said Thursday that they expected to adjust the grading system, in effect ensuring that more schools would receive lower grades next year.
In fact, school officials who helped create the system said they never meant it to be one that would have so many schools earning the highest marks.
"We are going to raise the bar," said Shael Polakow-Suransky, the chief accountability officer for the department. He said that while he would want to see a wider distribution of the grades, "At the same time, when we set clear goals and schools meet them, they need to be recognized and rewarded for that."
The huge increase in the number of top marks on the city report cards -- 97 percent of schools received an A or B, up from 79 percent in 2008 -- was driven by broad gains on state standardized tests in math and English. This year, the number of students who met state standards jumped to 82 percent in math, compared with 74 percent last year. In English, 69 percent of students passed, up from 58 percent.
