For a child with Rett Syndrome it usually points to communication (often via eye-gaze/AAC), hand function, mobility and comfort. The next step is a clinician-led profile review to set 2–3 meaningful goals and begin a coordinated plan.","answer_md":"*An AbilityScore in the 100–200 band is not a verdict — it's a starting map, and with Rett Syndrome it tells us exactly where to begin building.*\n\n## In short\nAn AbilityScore band of 100–200 simply describes where your child's current developmental profile sits *today*, against their own baseline — it is a planning tool, not a ceiling. For a child with [Rett Syndrome](/), this band usually points to a focus on communication, hand function, mobility and daily comfort. The next step is straightforward: review the full profile with your Pinnacle clinician, agree a small set of meaningful goals, and begin a consistent, multi-disciplinary plan.\n\n## What this band means for a child with Rett Syndrome\nRett Syndrome (ICD-11 **LD90.0**) affects children in a distinctive way — there is often a period of regression followed by stabilisation, and many children retain far more *understanding* than they can show through speech or hand use. A score in this band typically means the priorities are:\n\n- **Communication first** — many children with Rett respond beautifully to eye-gaze and AAC (alternative and augmentative communication) systems, because comprehension often outpaces expressive ability.\n- **Hand function & purposeful movement** — supporting whatever the child *can* do, and reducing the impact of hand stereotypies on daily tasks.\n- **Mobility and posture** — protecting walking, sitting balance and comfort, working closely with physiotherapy.\n- **Comfort and regulation** — supporting breathing patterns, sleep and calm, which directly free up a child's energy for learning.\n\nProgress with Rett is real but often quiet — measured in a steadier gaze, a chosen symbol, an easier transfer. The band lets us see that quiet progress objectively over time.\n\n## How to move forward\n1. **Book a profile review** so the clinician can interpret the band alongside your child's history and medical care.\n2. **Set 2–3 meaningful goals** tied to daily life — not a long list.\n3. **Begin a coordinated plan** across speech, occupational and physiotherapy, with you as the central partner.\n4. **Re-measure** against your child's own baseline, never against other children.\n\n## The Pinnacle way\nA clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under the care of a qualified clinician — never from a number alone or an online form. Our team brings 25 million+ therapy sessions of experience across 70+ centres to plan gently and precisely around *your* child. Start with [speech & communication therapy](/speech-therapy), understand the measure itself at [how the AbilityScore is calculated](/ask/what-is-the-abilityscore-and-how-is-it-calculated), and learn more about supporting your child at [Rett Syndrome](/).\n\n## Trusted sources\nWHO ICD-11 (LD90.0, Rett Syndrome); American Academy of Pediatrics guidance on developmental and behavioural support; ASHA guidance on AAC and complex communication needs; Pinnacle Blooms Network clinical studies.\n\n**Next step —** Turn this band into a clear plan. [Book a profile review](/enroll) with your Pinnacle clinician to agree your child's next two or three goals.\n\nThis is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.","canonical":"https://pinnacleblooms.org/ask/my-child-with-rett-syndrome-has-an-abilityscore-of-100-200-what-should-we-do-next","editorial":{"reviewed_at":"2026-06-11T20:12:18.613642+00:00","reviewed_by":null,"developed_by":"SETU Consortium · Pinnacle Blooms Network"},"alternates":[{"href":"https://pinnacleblooms.org/ask/my-child-with-rett-syndrome-has-an-abilityscore-of-100-200-what-should-we-do-next","lang":"en","indexable":true},{"href":"https://pinnacleblooms.org/ask/my-child-with-rett-syndrome-has-an-abilityscore-of-100-200-what-should-we-do-next-te","lang":"te","indexable":true}],"dimensions":[{"key":"conditions","label":"Conditions"}],"meta_title":"Rett Syndrome: AbilityScore 100–200 Next Steps","meta_robots":"index, follow, max-image-preview:large","everyday_tip":"Offer real choices through the eyes: hold up two objects a little apart and ask 'Which one?'
