Building a full EI caseload in New York City is genuinely achievable in 4–8 weeks for most disciplines if you approach it right. The city has consistent demand — 70,000+ children are in the EI program annually — and the provider shortage that's been growing since 2019 means qualified therapists don't sit idle for long.
What follows is a practical guide to getting to a full caseload as fast as possible, whether you're brand new to EI or re-entering after time away.
Step 1: Sort out your DOH approval first
Everything in NYC EI flows through your NYS Department of Health Early Intervention Provider Agreement. You cannot bill for sessions until you have it, and some agencies won't let you start with families until it's in hand.
Apply as soon as you have your NYS license. The application is submitted through the NYSDOH's provider enrollment system. Processing time runs 4–8 weeks and there's no way to speed it up meaningfully — but you can start the agency onboarding process in parallel so you're ready to take cases the day your approval arrives.
A few agencies will let you shadow or observe during the approval window. Worth asking.
Step 2: Join two agencies at the start, not one
The single biggest mistake new EI therapists make is signing with one agency and waiting for cases. One agency has one pipeline of available cases in one geographic area. Two agencies doubles your access to cases and halves the time it takes to fill your schedule.
There are no exclusivity requirements in NYC EI. Working with two or three agencies simultaneously is standard practice and expected. Agencies know this.
A smart starting pairing is one tech-forward agency with a strong citywide case pipeline (like Bloomer Health) and one borough-specific or specialty agency that covers a gap. If you live in Brooklyn, that might be Bloomer plus Puzzle Pieces. If you're in Staten Island, Bloomer plus Thrive By 5.
Step 3: Geographic concentration beats geographic spread
Resist the temptation to accept cases in every borough because you want more volume. A caseload spread across Manhattan, Queens, and the Bronx can easily cost you 2–3 hours in transit every day — time you're not getting paid for.
The faster path to a sustainable full caseload is concentration: build density in two or three neighborhoods close together. A caseload where every case is within a 20-minute walk or one subway transfer looks like a lot less work on paper but earns you just as much — and leaves room for a second cluster.
The best agencies let you filter available cases on a map. Use it ruthlessly. Decline cases that are inconveniently located even when your caseload is thin. A case 45 minutes away looks like $65 but costs you 90 minutes of your day.
Step 4: Know your caseload target by income goal
How many cases you need depends on what you're trying to earn. Some rough math for a licensed SLP at $65/session:
- Supplement to another job: 6–8 cases per week, 2–3 sessions each = 12–24 sessions/week, roughly $800–$1,500/week gross
- Transition to EI full-time: 16–20 active cases averaging 1.5 sessions/week = 24–30 sessions/week, $1,560–$1,950/week gross
- Maximum sustainable caseload: 22–28 active cases. Above this, documentation time compounds significantly and most therapists report burnout within a few months.
Step 5: Accept cases slightly outside your preference zone at first
When you're building from zero, be more flexible on location and case type than you will be once you're full. Accept a case slightly farther away than ideal. Take a feeding case even if it's not your strength. Say yes to the daycare case even if you prefer home visits.
Why: caseloads fill by momentum. Families talk to their service coordinators, who remember the providers who picked up quickly. Being known as responsive and flexible early builds your reputation as someone to route cases to. Once you're full, you can be selective — the therapists with full caseloads are usually the ones who were easy to work with when they were starting out.
Step 6: Respond fast when a case comes your way
This sounds obvious but it's the most commonly cited factor from agency administrators. Cases get routed to the first therapist who responds. If an agency sends you a case notification and you wait two days to reply, it's gone.
Set up push notifications from your agency's platform or app. Respond within a few hours when you're available, even if just to say you need a day to review the location. Agencies will keep routing to you if you're reliably responsive.
Disciplines with the fastest caseload build in NYC right now
All disciplines have demand in NYC, but these three fill fastest in 2026:
- SLP (speech-language pathology). NYC has a persistent SLP shortage in EI, especially in the outer boroughs and among bilingual providers. SLPs with Spanish or Mandarin ability can fill a caseload in 2–3 weeks.
- Special Instruction. The lowest barrier to entry in terms of licensing requirements (NYS teaching certification). Cases are plentiful and agencies hire aggressively.
- ABA Therapy. Autism cases represent a growing portion of the EI caseload. BCBAs are in particularly high demand. RBTs typically need more time to fill because there are more of them, but demand is still strong.
OT and PT fill well in Manhattan and Brooklyn but can be slower to fill in the Bronx and Staten Island, partly because fewer OTs and PTs live in those boroughs and commute willingness is lower.
How to maintain caseload once you have it
Caseloads naturally churn as children age out of the program at age 3 or achieve their IFSP goals. A typical EI case lasts 6–18 months. To maintain a full caseload, you'll need to take on new cases at roughly the same rate old cases close.
The easiest way to do this: stay active on your agencies' platforms even when you're full. When a case closes, you want to be visible and available so the next available case comes to you. Some agencies let you set a status as "accepting new cases" — use it.
