Pediatric Evaluation of Disability Inventory
PEDI vs the AbilityScore developmental assessment
The PEDI and AbilityScore® both measure functional abilities but answer different questions. The PEDI focuses on self-care, mobility and social function for young children with disabilities, often via structured parent interview. The AbilityScore® is a clinician-administered structured assessment mapping a child across many developmental domains against their own baseline to guide therapy. They complement each other, and any diagnosis comes only from a qualified Pinnacle clinician.
Wondering how a well-known disability inventory stacks up against the assessment your Pinnacle clinician uses?
In short
The PEDI and the AbilityScore® both measure a child's functional abilities — but they answer slightly different questions. The PEDI is a respected, internationally used inventory focused on self-care, mobility and social function, usually for children with disabilities aged roughly 6 months to 7.5 years. The AbilityScore® is a clinician-administered structured assessment that maps your child across multiple developmental domains against their own baseline, to guide a personalised therapy plan. They complement rather than replace one another — and any diagnosis comes only from a qualified clinician.How the two compare
Think of them as two lenses on the same child:- What they measure — The PEDI looks closely at functional skills in three areas: self-care, mobility and social function, plus how much help (caregiver assistance) a child needs. The AbilityScore® takes a broader developmental view across communication, cognition, motor, social-emotional and daily-living abilities.
- Who completes it — The PEDI is often gathered through structured parent interview or clinician judgement. The AbilityScore® is always administered by a trained Pinnacle clinician, blending your history with direct observation.
- Age and purpose — The PEDI is well validated for children with disabilities in the early years and is widely used to track functional change. The AbilityScore® is designed to turn a full developmental picture into a practical, measurable therapy roadmap.
- How progress is read — Both can track change over time. The AbilityScore® measures your child against their own previous baseline, so progress is personal rather than only compared to a norm.
Neither tool is a label or a verdict — each is a way of seeing strengths clearly and planning support kindly.
When each helps
If your child is already in physiotherapy or occupational therapy for a known physical disability, a PEDI-style functional inventory is excellent for tracking everyday independence. If you want a broad, multi-domain picture to decide which therapies will help most, a clinician-administered AbilityScore® at a Pinnacle centre gives that wider map. Many families benefit from both perspectives working together.The Pinnacle way
A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under the care of a qualified clinician — never from an online figure or a single form. The AbilityScore® is a clinician-administered structured assessment that measures your child against their own baseline and shapes a personalised plan, drawing on 2.5 billion+ data points and 25 million+ therapy sessions across 70+ centres. Explore what the AbilityScore is and how it's calculated, and see how it links into occupational therapy for everyday skills.Trusted sources

What to watch
If your child has a known physical disability and is in physio or OT, a PEDI-style functional inventory tracks everyday independence well. If you want a broad, multi-domain picture to decide which therapies will help most, a clinician-administered AbilityScore offers that wider map — and many families benefit from both.
Try this at home
Whichever measure is used, keep a simple home note of small wins — dressing independently, a new word, climbing stairs alone. These everyday observations help your clinician read progress accurately between assessments.

Frequently asked
Is the PEDI better than the AbilityScore?
Neither is simply better — they answer different questions. The PEDI focuses on functional skills (self-care, mobility, social function) for young children with disabilities, while the AbilityScore® gives a broader multi-domain developmental picture to guide a therapy plan. Many families benefit from both perspectives.
Can the AbilityScore replace the PEDI?
Not exactly. The AbilityScore® is a clinician-administered structured assessment with a wide developmental scope, while the PEDI is a focused functional inventory. Your Pinnacle clinician will advise which measures suit your child's needs and goals.
Who administers the AbilityScore?
The AbilityScore® is always administered by a trained Pinnacle clinician at a centre, blending your history with direct observation. A clinical AbilityScore® and any diagnosis are formed only under qualified clinician care.
