The PEDI is indicated for measuring everyday functional capability and caregiver assistance in children roughly 6 months to 7.5 years (PEDI-CAT extends further), across self-care, mobility and social function. Its strength is ecological, function-focused profiling well suited to cerebral palsy, developmental delay and acquired injury; its limits are informant reliance, classic-version floor effects in young children, and that it is functional rather than diagnostic.

*The PEDI shines when you need a true picture of a young child's everyday function — not just what they *can* do in a test room, but what they actually do at home.*

## In short
The [Pediatric Evaluation of Disability Inventory (PEDI)](/pedi) is indicated when you need a structured, norm-referenced measure of functional capability and caregiver assistance in children roughly **6 months to 7.5 years** (with the computer-adaptive PEDI-CAT extending into adolescence). It captures three domains — self-care, mobility, and social function — across both *capability* and *caregiver assistance/modifications*, making it well suited to children with cerebral palsy, developmental delay, acquired injury, or complex disability. Its strength is ecological, function-focused profiling; its limit is that it relies on informant report and is not a discriminative diagnostic test.

## When it is indicated
Reach for the PEDI when the clinical question is **functional**, not diagnostic:

- **Baseline functional profiling** in cerebral palsy, global developmental delay, spina bifida, traumatic or acquired brain injury, and other disabling conditions.
- **Goal-setting and rehab planning**, because it separates what a child is *capable* of from how much *caregiver assistance* and *environmental modification* they currently need — a distinction that directly shapes therapy targets.
- **Outcome measurement over time**, given its sensitivity to change in paediatric rehabilitation.
- **Eligibility and service-planning** decisions where a defensible, standardised functional record is required.

The original PEDI uses structured interview/observation with caregivers and clinicians; the **PEDI-CAT** uses item-response-theory-based computer-adaptive testing to shorten administration and reduce floor/ceiling effects.

## Strengths and limits in early childhood
**Strengths**
- Genuinely *ecological* — measures real daily function across self-care, mobility and social participation.
- The capability-versus-assistance split gives a richer, more actionable picture than a single ability score.
- Norm-referenced and scaled scores support both peer comparison and individual progress tracking.
- Strong responsiveness to change, useful for demonstrating rehab outcomes.

**Limits**
- It is **informant-based** (parent/clinician report), so accuracy depends on caregiver familiarity and recall.
- It is a **functional, not diagnostic, instrument** — it characterises disability, it does not identify aetiology.
- The classic version has **floor effects** in very young or profoundly affected children (mitigated by the PEDI-CAT).
- It assesses function in context but does not replace domain-specific assessments (e.g. standardised motor, speech or cognitive testing).

## The Pinnacle way
Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under the care of a qualified clinician — never from a form or an online figure. Our clinicians use validated tools such as the PEDI alongside our own clinician-administered [AbilityScore® structured assessment](/ask/what-is-the-abilityscore-and-how-is-it-calculated) to build a function-first picture, then convert it into measurable therapy goals. Backed by 2.5 billion+ data points and 25 million+ therapy sessions across 70+ centres, findings flow directly into individualised [occupational therapy](https://www.pinnacleblooms.org/best-occupational-therapy-center-india-proven-improvement-rate) and allied care that target self-care, mobility and participation.
