Gainey spoke Thursday for the first time since Tony Tata was fired by the school board.
Gainey will lead the district for at least the next 60 days.
The board is in the process of making up the new student assignment plan for next year after this year's choice plan raised plenty of complaints.
Gainey said his main role will be to provide support.
"We're going to work with the board," said Gainey. "My staff role is going to be to provide information and guidance and recommendations. We'll follow the board's direction on which way we go."
Gainey said there's no time to lose focus because there are students depending on the system to move forward.
