The founder of the Hartford school, Steve Perry, said in an interview on Monday that it was unclear what role Mr. Combs would play in the new school. Beginning in 2011, Mr. Combs recruited Mr. Perry to bring his educational model to Harlem, provided office space and quietly rallied support in the community, Mr. Perry said.

“It’s important to note it was he who inspired our team to come in and expand into New York,” Mr. Perry said. “It starts there, and the rest of the role will develop over time.”

The school is set to open for the 2016-17 school year, with 160 students in sixth and seventh grades. School officials said it would expand one grade per year, eventually enrolling 700 students in grades six through 12. It is currently accepting applications for students and staff members.

Mr. Perry said that he initially resisted Mr. Combs’s suggestion of opening another school — suggesting an after-school program or a scholarship instead — but that Mr. Combs was adamant.

“I think that there’s a lot to be found in the fact that you have someone such as Combs, who is highly visible within our community, who has decided that his major push is going to be with our model and in education,” Mr. Perry said.
