The Danbury Board of Education is expected to vote tonight on Superintendent Kevin Walston's proposed budget for the coming academic year.  The $152 million proposed budget is a 6.2 percent spending increase, after grants and surplus funding from previous years is taken into account.  More than 30 new staff members would be added under the plan.  Danbury’s enrollment continues to grow, including a disproportionate number of high-need students such as English language learners and those who require special education.  Danbury needs 12 more teachers in bilingual, world language and English as a second language.  Social workers and counselors would also be added.  Walston reiterated in budget presentations that Danbury spends less money per student than all the other district in the state of Connecticut.  Health insurance, transportation, security and supply costs are also up.
