HB 199 requires Texas school districts to hold bond elections for voter approval on specific, standardized dates - either a general primary election, general election for state/county offices, or the May uniform election date. This directly affects all school districts seeking bond issuance, as they can no longer schedule these elections on arbitrary dates. The bill mandates that school boards must align bond elections with existing statewide election schedules, eliminating district discretion over election timing. This change streamlines the voting process by ensuring bond votes occur during established election cycles, reducing administrative complexity for districts.
