New York City's June graduation rate rose to 71.1%, up from 70% the year before.
While graduation rates are up, dropout rates are at an all-time low citywide, and more high school seniors are going to college - about 57 percent of the class of 2016, according to de Blasio.
The graduation rates are determined by the number of students who graduate in four years divided by the number of students who started ninth grade.
"New York's graduation rate continues its steady, upward trend", Education Commissioner MaryEllen Elia said in a statement.
"It's clear that more support needs to be provided to black and Latino students", Davids said.
Some critics have questioned the significance of ever-rising graduation rates, noting constantly changing state standards along with credit-recovery options for lagging students.
High-school graduation rates in New York City and statewide continued to inch up past year, according to state data released Wednesday.
The West Ada School District, Idaho's largest district, has a 84.7 percent graduation. State education officials say black, Hispanic and white students all made small gains in the four-year graduation rate, but a 20-point gap exists between white students and their minority peers. The Boise School District's graduation rate was 82.9 percent.
All but two of the eight local districts - Nyack and Suffern - saw slight drops in rates, though every district except for East Ramapo continues to maintain a percentage that is higher than the state's average of 80. Last year, the Legislature approved increased funding for college and career advising and the State Board has requested an additional $5 million this year to expand those efforts to freshmen and sophomore students. The Idaho Distance Education Academy posted the highest rate among virtual schools, at 75.5 percent. The organization said "closing the opportunity gap requires real investment in education equity".
"In order to achieve real progress in student outcomes including graduation rates in high need districts, many of which serve Black, Brown and low-income communities, the Governor and State Legislature need to commit to fully funding equity in this year's budget with a commitment to fully phase in the Foundation Aid formula". They also posted the highest gain from previous year with a 1.8-point hike. "Despite what the Governor believes, money does matter when it comes to educational outcomes; studies show that a 10 percent sustained increase in school funding leads to an 11 percent increase in graduation rates".
