NJEIS intake for children under three runs through the Central Regional office. In a county this dense, the single most useful habit is submitting the referral the week you decide to make it rather than waiting for the next pediatric visit to confirm what you already suspect. The federal timeline starts at referral, not at the appointment where someone finally says the word out loud.
Edison is one of the biggest districts in the state and schedules evaluations at volume, which in practice means close to the deadline rather than comfortably ahead of it. Keep the dated copy of your written referral and follow up if two weeks pass in silence. Piscataway and Woodbridge both run preschool disabled classrooms across several elementary buildings, so the placement discussion is partly about which building and how the bus routes there. New Brunswick handles a high volume of early childhood referrals and offers bilingual evaluation; if English isn't the language spoken at home, request the evaluation and the IEP meeting in your language at the referral stage, not on the day of the meeting. South Plainfield is compact by comparison, with fewer alternatives but a shorter path to an answer.
In every one of these districts the questions that matter are the same: what is the adult-to-child ratio in the proposed room, is it integrated with typically developing peers, and how many segments of speech and occupational therapy come with the placement. Larger districts are not slower by rule — the state timeline binds them equally — they simply use more of it.
Piscataway is a 10 to 15 minute drive from New Brunswick and Highland Park along Route 18 and River Road, and roughly the same from Edison via Stelton Road. South Plainfield and Bound Brook are close behind. Woodbridge families should budget closer to half an hour and should avoid the 287 approach near the Route 18 interchange at rush hour, where the merge does most of the damage. Somerset County families along Route 22 frequently use Piscataway as their nearest center as well.
