The news wasn't quite as bad for high schools as it was for elementary and middle schools this fall, but report card grades are down all-around this year.

The city gave 331 high schools an "A" through "F" letter grade on Wednesday. Forty-six schools went up at least a grade, while 82 schools went down. But most stayed the same.

"This is very sophisticated stuff and I believe very accurate in looking at different schools that are performing in different ways making different progress and rolling it up into an overall score that I think is meaningful overall," said Schools Chancellor Joel Klein.

Scores are based on attendance, how quickly students earn credits, graduation rates and surveys of students, parents and staff. High school grades have been more consistent from year to year than those for elementary and middle schools, which rely heavily on state test scores.

"We've had issues with the one's they're using for K to 8. We've always been very happy with the one's for high schools because they're a finished product," said Principals Union President Ernest Logan.

This year, the breakdown is as follows:

• 133 schools (40%) received an "A"
• 97 schools (29%) received a "B"
• 69 schools (21%) received a "C"
• 23 schools (7%) received a "D"
• 9 schools (3%) received and "F"

The highest scoring school was Theatre Arts Production Company School. The lowest score went to New Day Academy. Both are small schools in the Bronx.

Teachers and principals at schools that do well get cash bonuses -- soon to be announced. Schools that get a "D" or an "F" or three "Cs" in a row can be closed down. Officials say they're deciding which schools will go on the chopping block. One of those at risk is Herbert Lehman High in the Bronx. It did not receive a grade last year, since the principal is being investigated for tampering with students' grades. This year, it got an "F."

"On Lehman, I will obviously look at the entire record and we'll make appropriate decisions," Klein said.

Next year, the high school progress reports will start to measure how well graduates of each school do in college -- a big change that officials say fits their focus on preparing students to succeed after high school.
