The Council of Chief State School Officers has announced Carissa Moffat Miller as the group’s new executive director, effective March 19.

Miller currently serves as the interim executive director of CCSSO. Previously, she served as the group’s deputy executive director for membership and outreach for five years. She’s also been a deputy superintendent in the Idaho education department. The group said she will be the first woman to lead the organization in its history.

“As a first-generation college graduate, I know how important education is to opening doors and providing opportunities. I remain deeply committed to ensuring every child, across background and income level, has the same opportunity to succeed and thrive,” Miller said in a statement.

She will take over for Chris Minnich, who announced last year that he would step down from his post as CCSSO’s executive director. She appeared on an Education Week panel in 2016 to talk about the impact of Trump’s election, and has also defended how states have handled the Common Core State Standards—CCSSO oversaw the creation of those standards, along with the National Governors Association.

“Carissa is a proven leader who has strong experience at the state and national levels across K-12 and higher education. She is committed not only to the vision but to the work necessary to turn this vision into a reality,” said Carey Wright, Mississippi’s state chief and the president of CCSSO’s board, in a statement.
