The Pediatric Evaluation of Disability Inventory (PEDI) is designed for children aged from 6 months to about 7.5 years (roughly 6 to 90 months). It can also be used for older children whose functional abilities fall within that range, since it is the skill level rather than the birthday alone that guides its use. The PEDI measures real-world independence across self-care, mobility and social function, and is one tool among several a clinician may choose.

*A simple question with a clear answer — the PEDI is built for the early childhood years, with room to stretch further when a child's skills sit in that range.*

## In short
The **Pediatric Evaluation of Disability Inventory (PEDI)** is designed for children from **6 months to about 7.5 years (roughly 6 months to 90 months)**. It can also be used for older children whose functional abilities fall within that range — so it is the *skill level*, not just the birthday, that guides its use. The PEDI is a structured tool that looks at what a child can actually *do* in everyday life across self-care, mobility and social function.

## What the PEDI looks at
Rather than testing in isolation, the PEDI maps a child's real-world independence — dressing, feeding, washing, moving around the home and community, and joining in social routines. It captures both how much help a child needs and how they manage day to day, which makes it especially useful for understanding progress over time. Because it can be used a little beyond 7.5 years for children whose functional skills are still developing within that band, clinicians often choose it when they want a clear, practical picture of everyday ability rather than a single score in a quiet test room.

## When it is used
A therapist or clinician may draw on the PEDI as part of a wider developmental picture — for instance when planning therapy goals, tracking how a child responds to support, or understanding the impact of a developmental or physical difference on daily living. It is one instrument among several, chosen to fit the child and the question being asked, never used in isolation to label a child.

## The Pinnacle way
This is general information, not a diagnosis — a clinical [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care, never from an app or form. Our clinicians may use validated tools such as the [PEDI](/pedi) alongside their own structured assessment, then shape an individualised plan that can draw on [occupational therapy](https://www.pinnacleblooms.org/best-occupational-therapy-center-india-proven-improvement-rate) and other supports to build everyday independence.

## Trusted sources
Guidance from the American Academy of Pediatrics and HealthyChildren on developmental and functional assessment in early childhood; WHO and CDC resources on monitoring everyday developmental progress.
