"This has provided a growth and a transformation for the school and a real sense of stability," said Sister Nancy Fitzgerald, the principal. "When I register new families and I explain to them . . . that we are an independent Catholic school and that the archdiocese cannot close us, their eyes light up."
Her school has 400 students from kindergarten through eighth grade - 20 more than last year. Parents pay $2,460 per child.
The school's board, the archdiocese, and the nonprofit Business Leadership Organized for Catholic Schools (BLOCS) quietly signed documents in August 2010 making the school independent.
Officials are scheduled to publicly announce Tuesday the school's independence and its successful year-old transition.
"We're just thrilled that the group has come along to ensure that the school will continue," said Mary Rochford, superintendent of Catholic schools.
John F. "Jack" Donnelly, a business executive who is chairman of the Friends of St. Martin de Porres School Board, said the new approach shields the school from the cycle of rising costs and declining enrollment that causes several Catholic elementary schools to close each year.
"The goal is ultimately to use this as a model for other Catholic schools," said Donnelly, chief executive officer at L.F. Driscoll Co. L.L.C., a Bala Cynwyd construction-management firm.
A year ago, BLOCS pledged $4 million in matching grants to help St. Martin de Porres and six other urban Catholic schools create endowments. Although St. Martin de Porres has not yet raised the $5.75 million to qualify for its $225,000 match, the school is the first to become independent.
"We will be doing a full-court press" to get the match, Donnelly said.
