BOSTON (AP) — High school students in Massachusetts have improved their four-year graduation rate for the ninth consecutive year.

A report released Thursday by the state Department of Elementary and Secondary Education found that more than 87 percent of students who entered as ninth graders in the 2011-2012 school year graduated within four years.

The number includes students who transferred into that group during high school.

The state's annual dropout rate also declined to 1.9 percent in 2014-2015, dipping to the lowest overall rate in more than three decades.

The report found the graduation rate among Hispanic students exceeded 70 percent for the first time.

The report also noted that the graduation rate for urban districts crossed the 75 percent mark and the graduation rate for black females topped 80 percent.
