The troubled Hartford charter school management group known as FUSE continued to unravel Saturday when a new school about to open in New Haven announced it was ending its affiliation with the group.

Administrators of the New Haven charter school, the Booker T. Washington Academy, announced they were parting company with the Hartford-based Family Urban Schools of Excellence Inc. in a terse statement disseminated by email late Saturday afternoon.

The announcement was the latest in a series of blows to FUSE.

In eight days, FUSE’s CEO Michael Sharpe quit after it was learned he had been convicted of embezzlement and claimed falsely to have a doctorate degree, two more top administrators departed and the administration of Gov. Dannel P. Malloy, a long-time FUSE supporter, seemed poised to join its growing list of critics.

“It is with deep regret that effective immediately, the Booker T. Washington Academy. Inc. withdraws from its partnership with the Family Urban Schools of Excellence, Inc.,” said Pastor Eldren Morrison, chairman of the Booker T. Washington Academy board.

Morrison said in the statement that, to afford itself the “best opportunity at success in its first year of operation,” the New Haven school has “developed a plan to operate without FUSE that will allow its administrators, teachers, and professionals to focus on the work of educating New Haven’s children without unnecessary distraction.”

FUSE was created in 2012 as a management organization to oversee three Hartford charter schools known as Jumoke Academy schools. FUSE also manages Dunbar Elementary School in Bridgeport. Hartford announced it is discontinuing, a year early, a three-year agreement under which FUSE managed Milner Elementary School.

Earlier this year, the state approved the plan for FUSE to run the Booker T. Washington Academy, set to open in coming months. FUSE also planned to run another new charter school in Baton Rouge, La.

Since 1997, Jumoke has received $53 million in state grants, according to the Connecticut Department of Education.

It became apparent that FUSE’s fortunes had turned earlier this month when Hartford school officials decided to curtail the management group’s role at the Milner school, expressing concern about muddled curriculum, hiring practices and reading scores.

Within days, it was learned that Sharpe has twice been convicted of criminal charges — forgery in Connecticut in 1985 and embezzlement in 1989 in California — and he acknowledged he had used the title of Doctor without completing a degree.

Reversing the state’s earlier support of Sharpe and FUSE, the state education department is expected to meet Monday to appoint a special investigator to review the group’s finances and operations.

FUSE was to have run all aspects of the new New Haven charter — creating its budget and curriculum, hiring and training staff and evaluating student performance, among other things. In return, FUSE was to have collected a management fee equivalent to 10 percent of the school’s operating budget.

Because the state funds charter schools at the rate of $11,000 per student, the 225-student Booker T. Washington Academy is expected to receive at least $2.475 million for the 2014-15 school year.
