Boards of supervisors and municipal governing authorities are hereby authorized and empowered in their discretion to divide into two funds the levies which these respective bodies are now authorized and empowered by law to levy for school purposes for other than interest on bonds and bond maturities. One of these funds shall include funds necessary for the current expenses and maintenance of schools, the other fund shall include those items excluded from the term “maintenance tax” as set forth in the homestead exemption law. The levy producing the second fund will not be entitled to reimbursement from homestead exemption appropriations.
