Montgomery County schools will come up nearly 250 jobs short of initial expectations after the school board finalized a 2009 operating budget on Tuesday that will increase many teachers’ workloads while delaying planned reforms and expansions, especially at the middle school level.

The $2.1 billion budget will require 54 central office employees and 12 school-based employees to lose their current jobs, and an additional 182 planned-for positions to remain unfilled.
