Brownsboro ISD operates on a fiscal year that begins September 1 each year and ends the subsequent August 31. A plan of spending for the District, a useful budget has to be a flexible and adjustable document. From time to time, plans and ideas change with new leadership and as needs change, the budget changes. When the budget is changed within the fiscal year, it is through a budget amendment. Budget amendments that move funds between functions are approved by the Board of Trustees before they are available for use.
