EI (Early Intervention) serves children from birth to age three with developmental delays. CPSE (Committee on Preschool Special Education) serves children ages three to five. In New York City, both programs are large, both have persistent provider shortages, and both employ SLPs, OTs, and PTs in significant numbers.
They look similar on the surface but feel quite different in practice. The funding sources are different, the paperwork is different, the scheduling dynamics are different, and the clinical populations overlap but are not the same. A therapist who thrives in EI might find CPSE frustrating, and vice versa.
The quick comparison
| Factor | Early Intervention (EI) | CPSE (Preschool Special Ed) |
|---|---|---|
| Age range served | Birth to age 3 | Ages 3–5 |
| Governing body | NYS DOH / NYC DOHMH | NYC Department of Education |
| Service setting | Home, daycare, community | School, clinic, home (varies) |
| Per-session pay (SLP) | $58–$72 per 30-min session | $50–$68 per 30–45 min session |
| Employment model | Mostly 1099, flexible schedule | Mix of 1099 and salaried |
| Schedule control | High — you set your hours | Lower — school or clinic hours |
| Caseload size | Typically 12–22 active cases | Typically 20–40 on roster |
| Documentation burden | High (session notes, progress reports, IFSPs) | Varies — some settings lighter |
| Billing handled by | Agency (at best agencies) | Usually DOE or employer |
| Family involvement | Very high — parents in every session | Lower — often pull-out model |
| Clinical complexity | Moderate — birth to 3 profiles | Higher — more diagnoses, more complex |
| Career development | Mostly lateral | More paths to supervisory roles |
What EI does better
Schedule flexibility is unmatched
This is EI's biggest advantage over almost every other clinical setting. Because you're going to families' homes and daycares on their schedules, and because you work as an independent contractor, you genuinely control your time. You can build a caseload around school pickup, around a partner's schedule, or around a private pay practice you're growing on the side. CPSE in a school setting means showing up at 8am and leaving at 3pm. Not bad, but not flexible.
Higher per-session rate for short sessions
A 30-minute EI session at $65 is $130 per hour of billed time. A CPSE pull-out session in a school setting might pay a similar or lower hourly rate but locks you into a fixed location for the full school day. The effective per-hour compensation in EI is higher if you build your caseload efficiently.
Natural environment practice
EI sessions happen where children actually live — at home, at daycare, at the park. The research is clear that this produces better outcomes than clinic-based treatment, and it develops a different clinical skill set. Therapists who do EI well tend to become very good at coaching parents, which is a career-long skill that pays off in every subsequent setting.
What CPSE does better
More stability
A salaried CPSE position at a school or clinic is predictably $X per year, with benefits, PTO, and a retirement plan. EI income is inherently variable — case cancellations, family vacations, end-of-year transitions all thin your caseload. For therapists with mortgages and families, the CPSE salary model removes a genuine source of stress.
Richer clinical population (for some disciplines)
By age three, many children have formal diagnoses — autism, Down syndrome, cerebral palsy, rare genetic conditions. The clinical complexity in CPSE is generally higher than in EI, where many cases are developmental delays with no clear diagnosis. If you want to develop depth in a specific diagnostic area, CPSE gives you more of it.
Clearer career paths
A CPSE therapist in a large clinic or school district can become a lead therapist, clinical supervisor, department head, or director of therapy services. EI's independent contractor model doesn't have those ladders. If you're thinking 10 years ahead, CPSE offers more structured advancement.
The case for doing both
The most common approach among experienced NYC therapists is EI as a primary or supplemental income, with CPSE as additional work during the school year. The populations are adjacent — children transitioning out of EI at age three flow directly into CPSE — so the clinical knowledge transfers completely.
A typical combined schedule might look like: EI cases in the morning from 9am–12pm (home-based, flexible scheduling with families), CPSE in-clinic or school sessions from 1–4pm, finishing by 4:30pm most days. It's a long day but a very high earning day, and the variety reduces burnout.
Which should you prioritize if you're choosing one?
Choose EI if: You have childcare or family commitments that require a truly flexible schedule. You're new and want to build clinical confidence in a natural, low-pressure setting. You're a CF and want EI's strong supervision opportunities. You're bilingual and want to serve families in your language community. You're building toward private practice and want an income source that doesn't tie you to one location.
Choose CPSE if: You need income stability and benefits. You want to develop clinical depth with specific diagnoses. You're interested in leadership roles. You prefer being in one location rather than traveling between homes. You want more collaboration time with other therapists in a team setting.
The CPSE transition: when EI children age out
One thing EI therapists appreciate is that children who age out of EI at age three often transition directly into CPSE, and families frequently want to continue with the same therapist. If you're working with a child from age 18 months to age 3, their CPSE evaluation typically happens around their second birthday, and with parent preference, you can often follow them into CPSE at a different (sometimes higher) rate.
This transition pipeline means EI experience is genuinely valuable to CPSE providers. Agencies and clinics doing CPSE work often prefer hiring therapists with EI backgrounds because they already know how to work with young children in non-clinical settings and how to coach parents — skills that don't transfer automatically from adult or school-age caseloads.
