What's in the ECS Formula?

Jun 29, 2023 - less than 1 minute

The Education Cost Sharing (ECS) formula is the method the State of Connecticut has established to distribute approximately $2.2 billion annually in state education funding. The ECS formula is used exclusively to provide state funding to local and regional public school districts.

In October 2017, the Connecticut General Assembly passed a new ECS formula, which began being implemented in fiscal year 2019. Additional revisions to the ECS formula have been made since that time, including as part of Connecticut’s biennial state budget for FYs 2024 and 2025.

This one-pager compares the components of the ECS formula that was updated in 2022 and the most recent revisions to the formula.
