What does apportionment refer to at the federal level?

Apportionment at the federal level specifically refers to the process through which Congress releases funds for federal agencies to spend as part of the budget that has already been approved. Once a budget is legislatively established, apportionment is the mechanism that allows for the allocation of that budget in portions or segments, enabling agencies to utilize these funds over a specified period and for specific purposes.

This process is essential because it ensures that agencies receive access to resources in a controlled manner, allowing for financial management and oversight. It helps prevent agencies from overspending and promotes accountability by requiring them to adhere to the budgetary limits set forth in the legislative approval. This function serves as a crucial part of the management of public funds, reinforcing fiscal discipline within the federal government.
