• The rules are written and the clock is set. The state Department of Education issued updated guidance on January 15, 2026, one week after the signing, and every district’s policy must be in effect when school opens in September 2026.
   

• The money question is open, and there is a referee. New Jersey’s constitution contains a rule voters added in 1995, often called State Mandate, State Pay: if the State orders local boards to do something new without providing resources other than the property tax, a body called the Council on Local Mandates can declare the law an unfunded mandate, and it stops binding. Only a covered board (or certain officials) can raise the question. The report finds serious arguments on both sides: the funding was partial and is now gone, but a district can also comply at almost no cost by requiring devices to stay off and put away, which makes bigger spending a local choice. No board had filed as of August 6, 2026, and the report takes no position on the answer.
   

• The daily work lands on school staff. Collecting, storing, and returning devices, checking exceptions, and relaying parent messages through the main office are labor. Under New Jersey public labor law, districts and unions cannot bargain over whether to have the policy, which the statute commands, but they can bargain over its workload effects. The state’s largest teachers union supported the law and helped shape it, so the report expects cooperation rather than conflict, and it found no labor dispute filed anywhere as of its writing.
   

• Custody has consequences. When a school stores devices, loss, damage, and return become its problems, including when school closes unexpectedly. The cautionary tale is New York City’s early district ban, when students paid shops about a dollar a day, roughly $180 a year, to hold their phones, a cost that fell hardest on the lowest-income students. State guidance tells districts to plan storage, logging, and retrieval in advance.
   

• New York is a year ahead. Its statewide bell-to-bell rule began in September 2025 with $13.5 million for storage and a legal guarantee that parents can reach their child during the day, a guarantee New Jersey’s law does not include, leaving that to local policy. New York’s first-year results, and the first academic studies of them, will be the closest preview of New Jersey’s experience.

A practical step before September

The details that will matter most to your family are local. Before school opens, ask your district for its device policy: how devices will be stored, what happens the first time a rule is broken, and how a parent reaches a child during the day. If your child needs a device for a health condition, a disability plan, translation, or the care of a family member, the law protects that use; ask the school in writing how to request the exception, and expect it to be handled discreetly. Districts must explain the policy to students, families, and staff, and state guidance calls for translated materials and multiple channels. School board members and taxpayers should watch the first year’s real costs, storage purchases and staff hours alike, because that record, not predictions, will decide the funding question.
