In a special election held in September 2013, voters from Lambertville, Stockton and West Amwell Township passed referenda to dissolve the South Hunterdon Regional School District and to combine the three existing school districts from each municipality (Lambertville City School District, Stockton Borough School District and West Amwell Township School District), with majorities in each community passing both ballot items. A single combined regional district was created, serving students in pre-kindergarten through twelfth grade, in which property taxes are levied under a formula in which 57% is based on property values and 43% on the number of students. The executive county superintendent appointed an interim board of education for the new regional district, which was responsible for implementing the merger.
