Preparing for adulthood: the SEND transition nobody starts early enough

The move from children’s services to adult ones is one of the steepest drops a SEND family meets. The families who manage it best start years before it arrives.

Eighteen. That is the number the whole thing turns on, and it arrives whether or not anybody has prepared for it.

There is a moment that quietly frightens a lot of SEND parents, and it is not the diagnosis. It is not the first plan either. It is the realisation that the structures built around their child in childhood do not simply carry on into adult life. They change shape. They change rules. Some of them fall away, often at eighteen and sometimes earlier.

“Preparing for Adulthood” is the formal name for getting ready for this, and the phrase does the thing no favours. It sounds like an event with a date on it. It is not. It is a transition measured in years, and the commonest mistake families make is starting it far too late.

Why the drop is so steep

Children’s services and adult social care are different systems. Different thresholds, different assessments, different funding rules, and frequently different people at the other end of the phone. A child who comfortably met the criteria under children’s services can find that the adult system looks at the same young person and reaches a different view.

Education has its own version of this. The structured, legally backed world of the EHCP does not map neatly onto adult life, where the questions turn into employment, independent living, friendships and taking part in a community. The scaffolding that held childhood together has to be rebuilt for a different stage of life. Rebuilding takes time, however capable the people doing it.

Start at fourteen, not eighteen

Good practice says preparing for adulthood should be woven into a young person’s plan from around Year 9. Roughly age fourteen. In my experience, far too many families are not properly engaged with any of it until the transition is nearly on top of them.

Four years sounds like a luxury when you are deep in the day to day and struggling to see past next term. It is not a luxury. It is the runway, and you need every foot of it, because the questions genuinely take years to answer: what meaningful occupation looks like for your young person, what living arrangement is right, who funds which part of it, and how the various systems hand over to one another without dropping anything in the gap between them.

Quite often the timing is the only part of this process that is actually within your control. Everything else depends on other people’s thresholds, budgets and diaries. The one lever you hold is starting sooner than you are invited to.

The questions change shape

In childhood the questions are largely about education and care. In adulthood they broaden, and the broadening is the difficult part.

Employment, or meaningful daytime activity where conventional employment is not realistic. Where and how your young person will live, and with what support around them. Health, including the move from paediatric services to adult healthcare. Friendships, relationships, being part of something. The things that make a life rather than a care plan.

None of those is quick to answer. All of them benefit enormously from being thought about while there is still time to shape them, rather than assembled in a hurry in the final few months by people who are already worn out.

The financial transition runs alongside

Here the professional hat goes back on, because the financial transition is happening at the same time and it is easy to lose in the noise.

At eighteen the law treats your child as an adult. It does that whether or not they can manage their own affairs, which is a sentence worth reading twice. That single fact opens up a set of questions most parents have never had explained to them: deputyship, the Court of Protection, and who actually holds the legal authority to make financial decisions on your young person’s behalf. Knowing about all of that before the eighteenth birthday, rather than discovering it in a crisis a few weeks after, makes an enormous practical difference.

It runs into the benefits transition too. The move from DLA to PIP at sixteen. The way adult means testing works. Why how money is held for your young person can matter every bit as much as how much of it there is.

None of this is urgent when your child is fourteen. That is precisely why it is worth doing then.

The word to hold on to through all of it is continuity. The aim is not that nothing changes, because plenty will. The aim is that the change is a managed handover rather than a series of drops, and that the support alters shape without quietly disappearing while everyone waits for somebody else to pick it up.

That does not happen by accident. It happens because somebody, usually you, started early, asked the awkward questions ahead of time and refused to let each system treat the transition as another department’s problem. It is tiring to be that somebody, and I am not going to pretend otherwise.

Which brings us back to eighteen. It is only a number. It changes nothing about your young person on the morning of their birthday, and it changes almost everything about the systems standing around them. The distance between those two facts is the work. Start it at fourteen.
