Wednesday night is the last chance the Palm Beach County School District has to get the wording right on a referendum that will ask voters for more money later this year.
For the average homeowner with a $300,000 house, the property tax hike means paying an extra $225 a year.
The district says it needs the money for more school police, to pay for teacher raises and to harden school buildings.
Palm Beach County charter schools won't get a share of property tax money if voters approve an increase in November.
Schools Superintendent Dr. Donald Fennoy pulled back his recommendation to send some money to charters after school board members refused to approve it.
The Palm Beach Post reported that a private poll surveyed about 400 county voters in early May.
The poll results found that 59 percent supported raising a special property tax that provides extra money for public schools. While 32 percent of those polled opposed it and 9 percent were unsure.
