A coalition of lawmakers, business leaders and teachers unveiled the proposal (HB 29/SB 92) at a press conference Thursday.
Sen. Dorothy Hukill, R-Port Orange, called the measure "an economic no-brainer."
"Graduating seniors need to have a basic understanding of real world finance to be successful," she said.
The proposal has the support of Chief Financial Officer Jeff Atwater, the Florida Chamber of Commerce and the Business Law Section of the Florida Bar.
A similar proposal gained traction last year. But it died after some lawmakers voiced concerns about putting too many requirements on schoolchildren.
