The more people get to know Schools Chancellor Cathie Black, the more they disapprove of her, according to a new NY1-Marist poll. 
 
 Black's approval rating stood at 17 percent, down from 21 percent in February. 
 
 A Quinnipiac University poll released last month also showed a 17 percent approval rating for Black. 
 
 The school's chancellor is becoming better known, according to the latest Marist poll. Twenty-three percent of respondents said they don't know how to rate her or have never heard of her; down from 35 percent in February. 
 
 "Chancellor Black is still not on firm footing with New Yorkers," said Dr. Lee M. Miringoff, Director of the Marist College Institute for Public Opinion. "She's somewhat better known, but not better graded." 
 
 Black has been mercilessly booed at several events, including meetings where Department of Education panels voted to close schools. 
 
 From the New York Times: 
 
 Ms. Black has remained largely sequestered from the public since taking over in January from Joel I. Klein, and at public functions she commonly hews to scripted remarks or takes limited questions. She made a couple of gaffes in her first weeks in office, including one in which she jokingly recommended birth control as a solution to school overcrowding in Lower Manhattan. 
 
 The Marist poll also showed the Bloomberg Administration's efforts to vilify the United Federation of Teachers has been largely unsuccessful. 
 
 Fifty-five percent of people said the teacher's union does more good than harm, with 35 percent disagreeing. ||||| Michael Appleton for The New York Times

 Cathleen P. Black, a magazine executive with no educational experience who was named New York City schools chancellor last fall, stepped down Thursday, Mayor Michael R. Bloomberg announced. 
 
 Mr. Bloomberg called Ms. Black into his office Thursday morning and urged her to resign, officials said, ending a tumultuous and brief tenure for the longtime publisher. Mr. Bloomberg said at a news conference that he and Ms. Black had agreed that a change was required. 
 
 Ms. Black’s resignation, which follows a series of high-level departures at the Education Department, was nearly as surprising as her appointment. When Mayor Bloomberg plucked her from her post as chairwoman of Hearst Magazines to run the nation’s largest public school system, people in New York and across the country — including some of the mayor’s closest aides — were stunned. 
 
 Ms. Black will be replaced by Deputy Mayor Dennis M. Walcott, who has long aided the mayor in educational matters, Mr. Bloomberg announced at the news conference, at 11:30 a.m. at City Hall. 
 
 “I take full responsibility for the fact that this has not worked out as either of us had hoped or expected,” Mr. Bloomberg said. “But now it’s time to look forward, not back.” 
 
 Ms. Black’s time as chancellor was troubled from the start. During her three months on the job, she offended parents with an offhand joke about birth control and bewildered City Hall aides when she seemed to mock a crowd of parents protesting the closing of a school. Aides complained that she required intensive tutorials on every aspect of education policy. And on Monday, a NY1-Marist poll put Ms. Black’s approval rating at 17 percent, the lowest ever for a Bloomberg administration official. 
 
 Inside City Hall, mayoral advisers said, there was a growing sense that Ms. Black could no longer do the job. But Mr. Bloomberg is famously reluctant to dismiss members of his handpicked team, and Ms. Black remained resolute. 
 
 At a February town hall meeting of the District 14 Community Education Council, in Brooklyn, Ms. Black was booed and heckled, but told the parents and teachers in attendance, “I have a three-year term, and I am willing and excited to fulfill it to the absolute end.” 
 
 But eventually even Mr. Bloomberg agreed it was time for Ms. Black to go, the advisers said. 
 
 At the news conference, Mr. Bloomberg said he and Ms. Black had agreed that news about her handling of the school system had become overly distracting. 
 
 “Cathie and I decided that it would be better to have somebody else lead our education efforts,” he said. “We both agreed the story had really become about her and away from the kids, and that’s not good. We’ve got to focus on what’s good for the kids.” 
 
 Mr. Bloomberg praised Ms. Black, saying she had done “an admirable job pitching herself into the work” and that he had “nothing but respect and admiration for her and the work she has done.” Asked whether he blamed the news media for its coverage of her, he demurred, saying, “It is what it is.” 
 
 Mr. Walcott appeared at the news conference announcing the change, but Ms. Black did not. 
 
 Ms. Black’s resignation is a stinging setback for Mr. Bloomberg, who has made education a priority for his third and final term. It was also the latest sign of trouble inside an administration renowned for top-notch managers and high-function style. 
 
 In many ways, the episode seemed to confirm anxieties within City Hall about a third term, which has proved problematic for previous mayors. 
 
 When Mr. Bloomberg abruptly announced in November that Joel I. Klein, a former federal prosecutor who had spent more than eight years as chancellor, would be replaced by Ms. Black, he dismissed criticism that she was unqualified. “This is a woman who is eminently qualified,” the mayor said. 
 
 But on Thursday, Mr. Bloomberg made a point of noting Mr. Walcott’s numerous connections to the school system. Like Mr. Klein, Mr. Walcott attended city public schools and has spent years in public service. Mr. Walcott taught kindergarten for two years in Queens, Mr. Bloomberg said, and holds master’s degrees in education and in social work. Mr. Walcott also headed the Urban League for a dozen years, where he helped develop programs to prevent students from dropping out, the mayor said. 
 
 “For the past nine years, Dennis has been a key part of all our education reform issues,” Mr. Bloomberg said. “He has been involved in our schools at every level, as a student, as a teacher, as a parent and as a deputy mayor. His children, you should know, went to our public schools, and he has a grandson now in public schools. So I think there is no better person qualified to step into the job of chancellor at this point.” 
 
 Nonetheless, Mr. Walcott does not have all of the credentials required under state law, so before he ascends to the chancellorship he must get a waiver from the state education commissioner. In the interim, Shael Polakow-Suransky, the school system’s chief academic officer, will serve as acting chancellor, officials said. 
 
 Mr. Walcott, who grew up in Queens and whose grandparents immigrated from the Caribbean, said he was “very blessed” to lead the city’s schools, saying, “with my children, my grandson, we represent four generations of public school students.” 
 
 “To me, the great equalizer in society is ensuring that every child receives a quality education, especially a quality public education,” he said. 
 
 Early Thursday evening, Ms. Black briefly addressed a crowd of reporters who had gathered outside her Park Avenue apartment building. 
 
 “It’s been a great privilege to serve the city of New York and the mayor for three months,” she said. “I have loved the principals, the teachers and the kids. Dennis Walcott is a great guy. We have a wonderful relationship and I wish everybody the best.” 
 
 “I went out, I bought a new pair of running shoes today, so I’m off,” she added. 
 
 Ms. Black answered just one question: Asked how she felt, she replied, “I feel great.” 
 
 Robert Jackson, chairman of the City Council Education Committee, said his first indication that something was afoot came late Wednesday afternoon, when education officials asked to postpone a Council hearing on the school budget at which Ms. Black had been scheduled to testify. About 10:30 a.m, Mr. Jackson said, just before the news conference, Mr. Walcott called to tell him the news. 
 
 Mr. Jackson said he would have preferred a candidate with more experience as an educator but thought that Mr. Walcott would have the mayor’s ear. “Dennis is a seasoned diplomat,” he said. “But knowing Dennis Walcott, and knowing the role he has played as an advocate at the Urban League, and knowing he had children and has grandchildren in the public school system, I think that Dennis is on the ground.” 
 
 Jennifer Freeman, an Upper West Side parent leader who had been one of many to balk at Ms. Black’s lack of credentials, said, “I guess zero was not the optimal amount of education experience for a chancellor, after all.” She added: “While I am sure there will be many things to disagree with Walcott about, at least there will be a substantive base from which to have a discussion.” 
 
 Mr. Klein, in a statement, said Mr. Walcott was a “superb selection” who “knows the field of education” and is “a fighter for kids.” Mr. Klein’s predecessor, Harold O. Levy, also praised Mr. Walcott, describing him as a “class act” and “consummate listener.” 
 
 City Councilman Lewis A. Fidler, who represents Brooklyn, said Ms. Black’s tenure “was bad from the beginning,” adding, “It wasn’t properly vetted; it wasn’t properly thought out.” 
 
 Ms. Black, he said, “didn’t have either a unique qualification in education or a unique ability as a communicator in the public sphere.”
– Cathie Black has resigned just three months into her tumultuous tenure as New York City schools chancellor, and city officials tell the New York Times that mayor Michael Bloomberg gave her a strong nudge out the door. Many were stunned when Bloomberg appointed Black in the first place; she’s a magazine executive with no prior experience in education. “I take full responsibility for the fact that this has not worked out,” Bloomberg said in the announcement. Black had muddled into several controversies during her short reign, such as when she seemingly mocked a crowd of parents protesting a school closure, or jokingly recommended birth control as a solution to school overcrowding. She had an approval rating of just 17%, according to the Huffington Post.
