Jeff Bryant writes here about the billionaires who corrupted the school leadership pipeline. Chief among them, of course, is billionaire Eli Broad, who created an unaccredited training program as a fast track for urban superintendents.

Bryant has collected stories about how superintendents who passed through the Broad program hire other graduates of the program and do business with others who are part of their network. The ethical breaches are numerous. The self-dealing and the stench of corruption is powerful.

Bryant begins with the story of a phone call from Eli Broad to one of his graduates:

It’s rare when goings-on in Kansas City schools make national headlines, but in 2011 the New York Times reported on the sudden departure of the district’s superintendent John Covington, who resigned unexpectedly with only a 30-day notice. Covington, who had promised to “transform” the long-troubled district, “looked like a silver bullet” for all the district’s woes, according to the Los Angeles Times. He had, in a little more than two years, quickly set about remaking the district’s administrative staff, closing nearly half the schools, revamping curriculum, and firing teachers while hiring Teach for America recruits.

The story of Covington’s sudden departure caught the attention of coastal papers no doubt because it perpetuated a common media narrative about hard-charging school leaders becoming victims of school districts’ supposed resistance to change and the notoriously short tenures of superintendents.

Although there may be some truth to that narrative, the main reason Covington left Kansas City was not because he was pushed out by job stress or an obstinate resistance. He left because a rich man offered him a job.

Following the reporting by the New York Times and the Los Angeles Times about Covington’s unexpected resignation, news emerged from the Kansas City Star that days after he resigned, he took a position as the first chancellor of the Education Achievement Authority of Michigan, a new state agency that, according to Michigan Radio, sought “radical” leadership to oversee low-performing schools in Detroit.

But at the time of Covington’s departure, it seemed no outlet could have described the exact circumstances under which he was lured away. That would come out years later in the Kansas City Star where reporter Joe Robertson described a conversation with Covington in which he admitted that squabbles with board members “had nothing to do” with his departure. What caused Covington’s exit, Robertson reported, was “a phone call from Spain.”

That call, Covington told Robertson, was what led to Covington’s departure from Kansas City—because it brought a message from billionaire philanthropist and major charter school booster Eli Broad. “John,” Broad reportedly said, “I need you to go to Detroit.”

It wasn’t the first time Covington, who was a 2008 graduate of a prestigious training academy funded through Broad’s foundation (the Broad Center), had come into contact with the billionaire’s name and clout. Broad was also the most significant private funder of the new Michigan program he summoned Covington to oversee, providing more than $6 million in funding from 2011 to 2013, according to the Detroit Free Press.

But Covington’s story is more than a single instance of a school leader doing a billionaire’s bidding. It sheds light on how decades of a school reform movement, financed by Broad and other philanthropists and embraced by politicians and policymakers of all political stripes, have shaped school leadership nationwide.

Charter advocates and funders—such as Broad, Bill Gates, some members of the Walton Family Foundation, John Chubb, and others who fought strongly for schools to adopt the management practices of private businesses—helped put into place a school leadership network whose members are very accomplished in advancing their own careers and the interests of private businesses while they rankle school boards, parents, and teachers.

Covington’s tenure at the Education Achievement Authority in Michigan was a disaster, and the EAA itself was a disaster that has been closed down.

Bryant compares the Broad superintendents to a cartel.

The actions of these leaders are often disruptive to communities, as school board members chafe at having their work undermined, teachers feel increasingly removed from decision making, and local citizens grow anxious at seeing their taxpayer dollars increasingly redirected out of schools and classrooms and into businesses whose products and services are of questionable value.

In fact, Broad superintendents have a very poor track record. They excel at disruption and alienating parents and teachers by their autocratic style. Despite their boasts, they don’t know how to improve education. They are not even skilled at management.

What they do best is advance themselves and make lucrative connections with related businesses owned by Broadie cronies.
