CDC Learn the Signs. Act Early. Milestones
CDC-LTSAE vs the AbilityScore developmental assessment
The CDC-LTSAE milestones are a free, parent-friendly checklist for spotting whether your child is on track and acting early — a screening and awareness tool, not a diagnosis. The AbilityScore® is a clinician-administered structured assessment at a Pinnacle Blooms Network centre that profiles your child across multiple domains against their own baseline to guide a personalised plan. They complement each other: the checklist tells you when to look closer, the AbilityScore® tells you exactly where your child is and what to do next.
Both watch over your child's development — but one is a free awareness checklist, the other a clinician-administered measure of your child's whole-self growth.
In short
The CDC's Learn the Signs. Act Early. milestones are a free, parent-friendly checklist that flags whether your child is on track and prompts you to act early if something seems off — it's a screening and awareness tool, not a diagnosis. The AbilityScore® is a clinician-administered structured assessment done at a Pinnacle Blooms Network centre that measures your child across multiple developmental domains against their own baseline, to guide a personalised therapy plan. Think of CDC-LTSAE as the doorbell, and AbilityScore® as the detailed walk-through with a specialist.How the two compare
They serve different jobs at different moments in your journey, and they work beautifully together.- Who uses it. CDC-LTSAE is designed for you — parents and carers — to tick off at home. AbilityScore® is administered by a qualified Pinnacle clinician.
- What it's for. CDC-LTSAE answers "should I look more closely?" — a quick check by age. AbilityScore® answers "where exactly is my child, and what's the plan?" across communication, social, motor, cognitive and daily-living domains.
- Depth. The CDC checklist is a small set of yes/no milestones per age. AbilityScore® is a structured, multi-domain profile that becomes a baseline you can measure real progress against.
- Outcome. CDC-LTSAE points you toward acting early; AbilityScore® turns concern into a clear, personalised next step — neither, on its own, is a diagnosis.
- Cost and access. CDC-LTSAE is free and available to anyone; AbilityScore® is part of a clinical assessment at a Pinnacle centre.
When to use which
Use the CDC milestones any time you're curious or want a quick reassurance check at home — it's brilliant for catching things early. If the checklist raises a flag, or if your instinct says something needs a closer look, that's the moment to book a full assessment. Acting early is never wasted: the earlier we understand your child's profile, the more we can support their natural growth.The Pinnacle way

What to watch

Frequently asked
Is the CDC-LTSAE checklist a diagnosis?
No. The CDC's Learn the Signs. Act Early. milestones are a free awareness and screening tool to help you notice whether your child is on track and to prompt early action. A diagnosis is never made from a checklist — it requires a qualified clinician's assessment.
Can I use the CDC checklist and the AbilityScore together?
Yes, and they work well as a pair. Use the CDC checklist at home for quick, regular checks; if it raises a flag or you simply want a clearer picture, a clinician-administered AbilityScore® at a Pinnacle centre profiles your child across domains and guides a personalised plan.
What does the AbilityScore measure that a checklist doesn't?
The AbilityScore® is a structured, multi-domain assessment covering areas such as communication, social, motor, cognitive and daily-living skills, measured against your child's own baseline. It becomes a starting point for therapy and a way to track real progress over time — beyond a simple on-track/off-track tick.
