More schools received failing grades from Denver Public Schools this year, the last using the current rating system before the district implements changes for next year.
The annual ratings, known as the school performance framework, were released Monday.
According to the data, in the 2013-14 school year, 22 percent (34 of the district's 154 schools) were rated as accredited on probation or accredited on priority watch — the two lowest of the five, color-coded, ratings.That's up from 31 of 153 schools in the 2012-13 school year.
But the number of schools in the top, distinguished rating, also increased to 26 schools, up from 20 last year.
"We are seeing more and more blue schools, but we're also seeing more red schools," Superintendent Tom Boasberg said Monday. "That's a very significant cause for concern."
Boasberg held a news conference to release the data at McMeen Elementary, touting that it has received a distinguished rating — the highest possible — for the fifth time this year.
The charter network in DPS, Denver School of Science and Technology, also celebrated Monday because the top six schools in the district included five of the charters.
But Boasberg said district staff has been closely monitoring schools that move down on the ratings as well, and although each are different, he said one common factor is a lack of teaching quality.
"I recognize our teachers work very, very hard and have the challenge of reaching often 25 different kids with very different needs," Boasberg said. "It requires very small group instruction, very personalized instruction and a real effort to progress monitor kids."
