Patrick Exner will be making the jump this month from leader of a small suburban charter school to principal of Washburn High School, which is about four times larger.

Exner, 45, of Brooklyn Park, comes to Washburn from Ubah Medical Academy in Hopkins. He's the second principal in a row to be hired to run Washburn from outside the district, after Carol Markham-Cousins, whom he follows.

Exner is making the transition from associate director of a 320-student charter high school that mainly enrolls East African students to the more racially diverse 1,200-student Washburn. The formal announcement came last Friday, although word leaked out earlier last week.

"He helped a lot with the kids here," said Ubah Director Musa M. Farah. Exner was at Ubah three years, Farah said, and previously was director of teaching and learning for the West Metro Education Program, which holds more than 1,000 students in two schools. Most of his teaching career was spent at Cooper High School in the Robbinsdale district, where he taught writing and literature.

"Bernadeia's very high on him," said school board member Richard Mammen, referring to Superintendent Bernadeia Johnson.

Exner will face a difficult job at Washburn, a school where both faculty and students were riven by a well-publicized dispute over the replacement of Athletic Director Dan Pratt last spring that led to a walkout and a sit-in before Markham-Cousins was reassigned. Some parents also are pushing for increased academic rigor at the school as a new attendance boundary roped in more middle-class students from families with high academic expectations.

Cousins

Markham-Cousins argued that teachers should be able to differentiate their instruction to meet the needs of a wide range of students in the same class. The school's fine arts flourished under her tenure.

The district said in announcing Exner that enrollment increased by 25 percent under his tenure and math and reading proficiency improved. Results for last spring's tests haven't been released, but state data indicate that proficiency rose in math, science and reading at Ubah during his first year, but slid slightly below 2010 levels in his second. State figures show a 32 percent increase in enrollment.

Markham-Cousins was hired at Washburn in 2007-08 from St. Paul schools, where she had been an elementary principal. She had also served in secondary administration at Centennial High School in Circle Pines. She has been reassigned to head the school the district runs in the Hennepin County Juvenile Detention Center.

Three of the six people named by Johnson to fill principal vacancies in the coming school year have come from outside the district, although one later decided not to come and was replaced by a district assistant principal.

"It's really Bernadeia's willingness to get the best possible person," Mammen said. "Sometimes it comes from the system. Other times it comes from elsewhere."

Roger Aronson, who serves as attorney for the district's Principals Forum union, said he's not surprised that Johnson is looking outside. "These folks move around a lot," he said of the state's principals, whose association he also represents. He said the jobs have grown more demanding as pressure for accountability as measured by test results has increased. So superintendents are raiding each others' top performers.

He said St. Paul Superintendent Valeria Silva told him last week, "Everybody wants everybody else's people."
