IDP in Wales Explained

A Complete Parent Guide to Individual Development Plans

If you are navigating Additional Learning Needs (ALN) in Wales, you will hear one term again and again:

IDP — Individual Development Plan

But what an IDP actually means in practice is often unclear.

Parents are frequently told:

  • “Your child might need an IDP”
  • “We’ll review the IDP”
  • “The IDP is being drafted”

Without ever being shown: 👉 what a strong IDP looks like
👉 what your rights are
👉 what to do when things go wrong

This guide brings everything together in one place.

⭐ What an IDP Actually Is

An Individual Development Plan (IDP) is a legal document under the ALN Act 2018.

It sets out:

  • your child’s needs
  • the support required to meet those needs
  • who is responsible for delivering that support

If something is written clearly in Section 2 of an IDP:

👉 the Local Authority must secure it

If it is vague or missing:

👉 it is very difficult to enforce

⭐ The 4 Things Every Parent Needs to Understand

1. An IDP is enforceable (but only if written properly)

The difference between a weak and strong IDP is everything.

2. You can request an IDP at any time

You do not need to wait for school to suggest it.

3. The responsibility can sit with school or the Local Authority

This affects:

  • funding
  • provision
  • escalation routes

4. IDPs must be reviewed and updated

An IDP is not a static document.

If needs change: 👉 the plan must change

⭐ What Should Be in a Strong IDP

A strong IDP includes:

  • clear description of needs (Section 1)
  • specific, quantified provision (Section 2)
  • named responsibility (who delivers what)
  • frequency and duration of support
  • measurable outcomes

Weak wording looks like: ❌ “access to support”
❌ “opportunities to develop”

Strong wording looks like: ✔ “1:1 support for 60 minutes, 3 times per week delivered by…”

⭐ Health and Social Care in IDPs

IDPs are not just about education.

They can include:

  • Speech and Language Therapy
  • Occupational Therapy
  • mental health support
  • social care input

⭐ Private Diagnoses and IDPs

Parents often worry:

“Will a private diagnosis be accepted?”

The answer is: 👉 sometimes yes, sometimes no
👉 but it can still be powerful evidence

⭐ IDP vs IHP (Common Confusion)

Many parents are given an Individual Healthcare Plan (IHP) instead of an IDP.

These are not the same.

⭐ If the IDP Process Breaks Down

This is where many families struggle.

Common issues:

  • delays in drafting
  • vague provision
  • refusal to escalate
  • school retaining control when LA should take over

⭐ How IDPs Link to EOTAS

In some cases, an IDP leads to:

👉 Education Other Than At School (EOTAS)

This happens when:

  • school cannot meet need
  • attendance becomes unsafe or impossible
  • provision breaks down

⭐ The Reality Parents Are Not Told

The system works best when:

✔ needs are clearly evidenced
✔ provision is written precisely
✔ parents understand how to challenge decisions

It struggles when:

❌ language is vague
❌ responsibility is unclear
❌ delays go unchallenged

⭐ Final Thought

You do not need to become a legal expert.

You just need to understand:

👉 what your child needs
👉 how that must be written
👉 how to challenge when it is not

That is where things start to change.
