An estimate for the 2017-18 budget will likely be presented to the board of trustees in March, including new expenses for costs related to the successful 2016 bond referendum, SISD Chief Financial Officer Ann Westbrooks said.

Those costs include about $2 million for two new full-day prekindergarten classes and 60 new bus drivers, both part of the November 2016 bond package.

The district’s enrollment of 36,890 is expected to remain about the same for this school year, and property value in the district will increase by 7.5 percent, Westbrooks said.

“The funding environment we’re operating in and flat enrollment equals budget constraints and challenges,” Westbrooks said.
