Can a child get an IDP in Wales without a medical diagnosis?

Yes. A medical diagnosis is not required for a child or young person to be identified as having ALN or to receive an IDP in Wales. Support and ALN decisions should not be delayed solely because a family is waiting for an NHS assessment or diagnosis.

Wales has its own ALN framework. England EHCP guidance does not apply to learners educated in Wales.

What matters legally

The ALN test focuses on whether the learner has a learning difficulty or disability and whether this calls for additional learning provision. A medical label may help explain needs, but it is not the threshold for an IDP.

Useful evidence while waiting for diagnosis

What to ask the school

Ask what barriers the school has identified, what support has already been tried, what additional or different provision may be needed, and whether the school is making a formal ALN decision.

Do not wait for a label to describe need

Describe the actual difficulty: for example understanding language, regulating sensory input, recording work, reading, concentration, communication or attendance. This makes the conversation about provision rather than a diagnosis alone.
