Requires school district capital project referendums to be voted on at primary or general elections, or certain municipal or special elections.

S 3860 requires New Jersey school districts to hold capital project referendums (for school building or renovation projects) only during June primary elections, November general elections, or during municipal/special elections that include all legal voters of the school district. Currently, such referendums can occur during annual school elections (April or November) or special school elections on specific dates (January, March, September, or December). The bill also mandates the Secretary of State to coordinate with county clerks on how referendum questions appear on primary election ballots. This change amends existing statutes to standardize referendum timing across the state.
