The range at seven is much wider than most parents expect. Some children are reading chapter books, and others are still working out that the letters make sounds in a fixed order, and both of those children can end up perfectly fluent readers. Age on its own is a poor signal, which is why a single worried comparison at the school gate is rarely worth losing sleep over.

What is more useful than age is direction. A child who could not blend three sounds in September and can manage it, slowly, by December is moving. A child who is producing the same guesses in December that they were producing in September is not, and that flatness over months is the thing worth paying attention to rather than where they sit against a classmate.

It also helps to separate reading from everything around it. A child who listens to a story beautifully, follows the plot, asks good questions and then cannot decode a simple printed sentence is telling you something quite specific: the language is fine and the code is the problem. That is a much more hopeful picture than it feels like at the time, and it is a very teachable one.

The signs that tend to matter more than the calendar: effort that stays high long after classmates seem to have relaxed into it, reading a word correctly on one line and not recognising it three lines later, avoiding reading in ways that look like bad behaviour, and a gap between how bright your child obviously is and what they can get off the page.

If several of those are true and have been true for months, that is the moment for a closer look — not because something is necessarily wrong, but because finding out early is so much easier on a child than finding out at ten. An educational assessment describes how your child reads, spells and writes and what teaching would help. It is not a diagnosis, and where a formal diagnosis would be useful, a good assessor will say so and point you to someone qualified to make one.

One last thing worth saying to any parent reading this at eleven at night. A child who cannot yet read is not a child who cannot learn to read. Almost every child gets there with teaching matched to how they learn, and the ones who struggle hardest at seven are very often the ones whose parents noticed at seven.
