The complete guide

Chapter 1 of 9

Their Next Chapter is a site for parents and teens working out what comes after high school. If you're new here, start with how it works.

What's actually happening (and why you're not behind)

If your teen still can't name a plan, that's closer to on time than late.

The short version

The years right after high school are now seen as a stage of their own, and exploring is a normal part of it.

Your teen works this out from a steady base. In studies, support at home went with more exploring, and pressure with more trouble deciding.

There's no shared timetable. Going straight to a four-year school is common but far from universal, and living at home is ordinary at this age.

Your worry is real, so take it to a partner, a friend or a notebook instead of to your teen.

Aim for a decision your teen will stand behind and one small, real step to test it.

What's actually happening at 17 to 19

Your teen becomes a legal adult at 18 in most states. In the ways that take years, they're still becoming one. Living in that gap is normal at this age.

The stretch right after high school is now understood as its own stage. The psychologist Jeffrey Arnett named it "emerging adulthood" in 2000, running roughly from 18 to 25. Its normal features are exploring who you are, some instability, feeling in-between, a focus on yourself, and a wide sense of what's possible. If that list sounds like someone you live with, you're in the right chapter. A teen stuck on a decision is right in the middle of this stage.

Ask young people themselves what makes someone an adult and the answers are quiet and internal: taking responsibility for yourself, making your own decisions, and, over time, paying your own way. So "becoming their own person" is about owning choices, not about moving out or reaching a birthday. A teen wrestling with this decision is practicing exactly that.

Most people this age also don't feel fully grown yet. In Jeffrey Arnett's interviews, many said they were taking responsibility for themselves but still didn't completely feel like an adult (APA Monitor, 2006).

This work happens with you close by. In studies of teens and their parents, feeling supported at home went with more career exploring, and pressure or interference went with more trouble deciding (Dietrich and Kracke, 2009; Ahn and colleagues, 2023). Young people find themselves from a steady base they can leave and return to, which is how John Bowlby described a secure base in 1988.

That changes what's worth worrying about. A teen who says "I don't know yet" may be exploring rather than drifting. The pattern that tends to signal trouble is closer to the reverse, a cold pulling-away. Healthy growing-up keeps the bond and renegotiates it, so a kid staying close isn't failing to grow up.

Most 18-year-olds aren't on one timetable

The picture of the on-track 18-year-old, packed for a four-year school and gone by August, is less universal than it feels from the outside. A few numbers, as context and not as a target:

• Of 2022's roughly 3 million high-school completers, 62% were enrolled in college that October, 45% at four-year schools and 17% at two-year schools. So nearly four in ten weren't enrolled in college that fall (NCES, 2022 data). Going straight to a four-year college is common and far from universal.
• 57% of 18-to-24-year-olds live in a parent's home (Pew Research Center's analysis of 2023 Census survey data), and 68% of adults under 25 with a living parent got some financial help from a parent in the past year (Pew survey, late 2023, released January 2024).
• In that same Pew survey, which asked adults 18 to 34, 69% said a parent is as involved in their life as they'd like, and only 9% said a parent is more involved than they'd like. And 59% of young adults, along with 77% of parents, rate the relationship excellent or very good.

These figures are dated and shift a little from year to year, so treat them as a rough picture. What they show is that living at home, needing some help, and not having it all mapped out are the middle of the range. Money is one real factor in what comes next, one among several. These numbers are about how ordinary that help is, not what to spend.

A trade, a job, the military, a gap year, community college, a four-year school, starting something of their own, or a plan you'd describe some other way are all real options, and none of them is the assumed default. "Behind" only means something against a shared timetable, and there isn't one.

The first year after high school is mostly for gathering experience, the kind that shows your teen who they want to become, and it comes in many forms. Nobody settles that at 18. Your teen finds out by doing real things and noticing how each one sits with them, so every path on that list counts: each adds a piece of self-knowledge, a clearer sense of what fits and what doesn't. A first step that turns out not to fit still did its job, because it told your teen something true about what they want from this next chapter.

Your worry is real, and it needs a home that isn't your teen

None of this makes your fear silly. Many parents feel grief in this stretch, the quiet loss of the daily version of their kid, and that grief needs somewhere to go. It can't go to your teen. Worry poured onto them tends to land as pressure, and pressure is what an undecided kid pushes against. Take it to a partner, a friend, a walk, or your own notebook instead. (Chapter 5 gets into the conversation itself.)

Time is on your side, too. The developmental psychologist Laurence Steinberg argues that adolescence now runs from about 10 to 25, a stretch when the brain is especially able to change with experience (Age of Opportunity, 2014). Warm, steady support during these years fits what's actually going on in there, and your teen isn't late.

The finish line this guide aims at is smaller than a neat five-year plan: a decision your teen will stand behind, plus one small, real next step to test it. If you want the sequenced version that walks a family through getting there, that's the tool at /start. A calmer parent and a teen who isn't being rushed are the conditions a good decision gets made in.
