Most people don't wake up one day and decide, out of nowhere, to look into a dyslexia assessment. Something usually prompts it. The trouble is, the moments people wait for aren't always the right ones, and waiting for them can mean months, sometimes years, pass before anything actually happens.
The moments parents wait for:
Parents' evening is a common trigger. So is a school report, or the results of SATs. There's a logic to it, these are the moments when a teacher's observations are put in writing, so it feels like the natural point to act. But a screener or a set of results is only ever a snapshot, taken on a particular day, and concerns that have been building quietly at home for months don't need that snapshot's permission to be taken seriously.
If you've been noticing avoidance around reading, frustration with homework, or a gap between how capable your child clearly is and what ends up on the page, that's already enough. You don't need a parents' evening to validate what you're seeing.
Why adults often wait for a crisis:
For adults, the pattern looks different but comes from the same place. It's rarely a quiet, considered decision. More often it's reactionary, a difficult performance review, a course that suddenly feels unmanageable, a promotion that exposes gaps that were easy to hide before. Something forces the question, rather than the question being asked on its own terms.
For adults, the pattern looks different but comes from the same place.
That's understandable. Many adults have spent years building quiet workarounds, and it often takes a moment of real pressure to notice they're not enough anymore. But waiting for that moment isn't necessary, and it often means the assessment happens at the most stressful possible time, rather than a calmer one.
So when is the right time?
Whenever you're the one asking the question. Not after a specific event, not once things have got difficult enough to force the issue, but whenever the concern itself feels persistent enough to act on. That's true whether it's a parent noticing a pattern over several months, or an adult who's wondered about this for years without quite putting a name to it.
Earlier is almost always better, not because there's a deadline, but because clarity tends to open doors rather than close them, whether that's school support, exam access arrangements, or simply understanding yourself better.
If you're wondering whether what you're noticing is worth acting on, it's worth reading our guides on the signs of dyslexia in children and the signs of dyslexia in adults. And if you're an adult who's already sensed it might be time, we've written more on why now is often the right moment.

A final word
Choosing when to trust your gut at first glance seem difficult, but it is personal choice. Trust that gut!
