Darlah Krug has ended her short tenure as executive director at Woodbury Leadership Academy, the charter school she helped found in 2012.

In an end of year update sent to families earlier this week, the board of directors at the charter school said that Krug had resigned, along with manager of operations Becky Kullman and office manager Dekontee Lombel.

"The Director, Darlah Krug, has informed the Board that she does not intend to return next year," according to the letter, which was signed WLA Board. "We want to assure you that the Board is taking immediate action to fill all of the vacancies created by the departure of these staff members."

Board chair Barbara Young did not return a call seeking comment.

The board is expected to discuss the search for a successor at a special meeting Friday at the school. They hope to hire an interim director by the end of this month, according to the letter.

Krug, who became executive director in February, did not return emails seeking comment.

In Minnesota, charter schools are tuition free independent public schools that are governed and operated by licensed teachers, parents and community members. But parents and staff at Woodbury Leadership Academy have frequently clashed over the school's direction and what critics said was the board's over-reliance on closed meetings.

This school year has been marked by turmoil and turnover, including the resignation of executive director Dan Hurley, Krug's predecessor, and the departure of board member Michael Flint, who said he was forced out for his efforts to bring more transparency to board proceedings.

Earlier this year, the academy's leadership drew a rebuke from the Minnesota Department of Education for allegedly violating a state open meetings statute.

A document titled "Notice of Intervention 2", from the MDE's Compliance and Assistance Division, also cited a meeting on Nov. 24 in which the board accepted the resignation of two ineligible board members and rehired them at the same meeting - an attempt, it suggested, to skirt another statute that requires that new board members to receive training in "board role and responsibilities, employment policies and practices."

The letter to families, dated June 14, concluded by assuring parents that officials at Woodbury Leadership Academy were taking all the necessary steps to right the ship.

"....(T)he Board will be taking all other necessary steps to ensure the continued vitality and success of Woodbury Leadership Academy into 2016-17 and beyond. We will keep you informed as things move forward. We believe that WLA is and will continue to be a vibrant, dynamic school for all learners for many years into the future."
