Each state agency prepares a detailed legislative appropriations request (LAR) under the guidelines of the state’s Legislative Budget Board (LBB). These LARs itemize the funding each agency is requesting. By the end of summer or early fall, the LARs are generally submitted to the LBB and several other key state agencies. Hearings are held on the content and after the hearings, the LBB will use the LARs as a basis to prepare a draft of the state’s general appropriations bill, which will provide state agencies and institutions with funding for the following two fiscal years.
