Essentially, Levies are for learning support - staff in mosts cases - and bonds are for buildings.
Levies fund the day-to-day learning operations of a school district. In most cases this is staffing. Levies can also fund teaching/learning materials, classroom supports and technology tools and services. Typically levies have a 10-year life span.
Bonds fund major renovations or additions to the physical school buildings. Such improvements cannot be resourced through the facilities maintenance fund. Typically bonds have a 20-year life span or more.
A referendum is the holding of an election for levies and/or bonds. A levy referendum was held last year (Nov. 8, 2022), and a bond referendum is being held this year (Nov. 7, 2023).
Levies and bonds are independent of one another and must be utilized for their designated purpose.
