What should my teenager know before they leave home?
Quick answer
Five areas, done unaided.
Money, food, admin, household, and asking for help.
Roughly five areas: managing money end to end, feeding themselves, handling their own admin such as appointments and forms, basic household maintenance, and knowing when and how to ask for help. The most useful test is not whether you have taught something but whether they have done it unaided, repeatedly, while you were still around to catch the fallout. Anything they have only watched you do does not count.
What to consider
- Doing beats being told
- A skill demonstrated is not a skill acquired. The transfer only happens when you stop doing it, which is the hard part.
- How much time is genuinely left
- At fifteen there are about three years. Listing what is missing tends to be more motivating than it is alarming.
- Mistakes are cheaper now
- An overdraft at seventeen while living with you costs far less than the same mistake at nineteen alone. Let some happen deliberately.
- Admin is the commonly missed one
- Money and cooking get attention. Booking their own appointments, dealing with forms, and speaking for themselves usually do not.
- Your role changes
- From about sixteen the useful posture is consultant rather than manager. That shift is harder for parents than for teenagers.

Time remaining at each age
About 5 years at 13, 3 at 15, 1 at 17
Worth stating plainly, because the runway feels longer than it is.
Arithmetic
A workable pace
One skill a month, deliberately
Roughly thirty to thirty-six skills between thirteen and sixteen, which comfortably covers the essentials without it becoming a programme.

Your action plan
Do firstThis week
- List the five areas and mark honestly which your teenager has done unaided, not just watched.
- Pick the single biggest gap and hand that one thing over permanently, starting now.
- Have them book one appointment themselves, start to finish.
- Tell them what you will and will not fund after school. Do not leave it implied.
ThenNext month
- Move one real budget category onto them, with the money to cover it.
- Let one mistake stand without rescuing it, and talk about it afterwards rather than during.
- Teach one household maintenance task they will need in a first flat.
Keep an eye onWatch for
- Teaching by demonstration and never actually handing over.
- Rescuing every mistake, which removes the only useful part.
- Concentrating on money and cooking while admin and self-advocacy go untouched.
- Leaving it all to the final year, when there is no room for anything to go wrong.

You know what to do.
Now here’s the system to actually do it.
A year-by-year roadmap of the skills, money habits and decisions that need to be in place before your child turns eighteen.
The Road to 18
Prepare your child for adulthood before they need to be independent.
Recommended here because you are working on independence.
- For
- Ages 10 to 18
- The problem
- Your child is growing up, and it is genuinely hard to tell whether you are preparing them for independence or just getting through each year.
- What changes
- See which independence gaps are real, while there is still time to close them
- Hand over one area at a time, permanently, instead of all at once at seventeen
- Compare post-school paths on cost as well as on hope
Common questions
What if my child is already 17 and cannot do much of this?
Then triage. Pick money and admin first, because those cause the most immediate damage when missing, and accept that some things will now be learned after they leave.
How do I teach without it feeling like a lecture?
Hand over the task rather than explaining it. Doing the thing, with you available but not intervening, teaches faster and creates far less resistance.
Should they have a job?
A modest amount of work teaches things home cannot: turning up, being managed, and money that is genuinely theirs. The trade-off against schoolwork and sleep is real, so keep the hours contained.
