Intake for children under three goes through the NJEIS Northern Regional office. Caseloads in the county's urban districts run heavy, and the effect shows up later rather than sooner: a family that waits for the IFSP to be finalized before calling about private therapy often discovers the blocks they wanted filled in the interim. Start those availability conversations while the early intervention paperwork is still moving.
West Orange, Livingston, and Montclair each maintain their own preschool programs, and they do not use the same model. Livingston leans integrated, with related services attached to the IEP; West Orange runs both integrated and self-contained rooms; Montclair and South Orange–Maplewood carry larger caseloads and spread evaluations across several buildings, which is why the eligibility decision and the placement offer sometimes arrive in the same meeting. Ask for the draft in advance in those two districts especially — reading proposed goals cold, with a team waiting on your signature, is not a fair way to make a decision. Caldwell–West Caldwell is small enough that its sections fill; if a neighboring program is proposed, get the transportation plan and the named case manager written into the IEP rather than promised verbally.
The single most useful question in Essex is how related services are delivered. Pull-out, push-in, or consultation to the classroom teacher produce three genuinely different school days for the same number of minutes on paper, and districts here vary in what they default to.
Roseland sits just off Eisenhower Parkway near 280 and is the easier reach from Livingston, Caldwell, Essex Fells, and Verona — usually inside 15 minutes. West Orange is the shorter drive from Montclair, South Orange, and the Oranges, where the local streets matter more than the highway. Almost everyone in the county is within 20 minutes of one or the other, and Hanover-area Morris families sometimes find Roseland quicker than Parsippany depending on how 280 is running that afternoon.
