School Revenue ForecastK-12 funding now comprises almost half of the State General Fund Budget, and state funding is the primary source of K-12 revenue. With that in mind, the Governor's Revenue Forecast Committee was established in 1999. This committee's task is to calculate an "essential budget level" budget for K-12 schools. The figure is the amount of state funding required to keep the current level of program available in the state's K-12 system. The forecast is to be provided with the December 1 Oregon Economic and Revenue Forecast in even numbered years. Here is the latest forecast. The COSA Executive Director is a member of the committee.
