U.S. Secretary of Education Betsy DeVos announced Thursday that she has approved Massachusetts’ plan for the Every Student Succeeds Act.

In a statement, DeVos praised the plan’s details on turning around low-performing schools and for emphasizing the share of high school students who complete accelerated courses such as Advanced Placement and International Baccalaureate.

“I continue to be heartened by the ways in which states have embraced the flexibility afforded to them under ESSA,” DeVos said in her statement. She also praised the plan as a “testament” to the work of the late Commissioner of Education Mitchell Chester, who died earlier this year.

Massachusetts is the 14th state, along with the District of Columbia, to have its ESSA plan approved by the U.S. Department of Education. (Arizona, the preceding state to get approval, got the nod on Sept. 6.) That leaves two states in the first round of submissions, Colorado and Michigan, whose ESSA plans haven’t been approved yet.

Sixteen states and D.C. submitted ESSA plans by the first deadline in the spring. Another 30 states have submitted their ESSA plans before a second deadline of Sept. 18. Another four are due to submit them in a few weeks.
