The performances on the new exams, which were some of the first nationwide to be aligned with a more rigorous set of standards known as the Common Core, offered Mr. Bloomberg a chance to boast about his education record as his 12-year run as mayor comes to a close.
“Our administration’s core philosophy, when it comes to education, has always been, if we raise our expectations, our kids will meet them,” Mr. Bloomberg said at Talented and Gifted Young Scholars, a citywide gifted school in East Harlem that was one of the 22 high-scoring schools.
The mayoral blitz, carried out with militaristic precision, came as the two men campaigning to lead the city in the post-Bloomberg era have been offering a stark contrast on educational issues.
The Democratic nominee, Bill de Blasio favors undoing much of the Bloomberg administration’s centerpiece educational policies by slowing the growth of charter schools and ending, for at least a year, the practice of closing low-performing schools. The Republican candidate, Joseph J. Lhota, has defended the mayor’s record on education and wants to expand the number of charter schools.
