Six to eight weeks off is enough for decoding skills to go rusty — not gone, just rusty. Before term starts, a quick check plus a light 2-week tune-up gets most kids back to where they left off, without turning the last weeks of summer into school.
Is "summer slide" real?
Yes, and it hits decoding harder than almost any other reading skill. Sounding-out and blending are automatic only with regular use — a summer without any reading practice genuinely does make word-reading feel slower and more effortful in September. The good news: it comes back just as fast as it faded.

This is a quick gut-check, not a full assessment — for the real depth, see our age-by-age guides: 2-year-olds, 4-year-olds, 5-year-olds, and 6-year-olds.
| Age going into September | Should be comfortable with |
|---|---|
| 3-4 | Rhyming, clapping syllables, first letter sounds |
| 5 (Reception/K) | Most single-letter sounds, blending simple CVC words |
| 6 (Year 1/1st grade) | CVC words, common digraphs (ch, sh, th), some blends |
| 7 (Year 2/2nd grade) | Vowel teams, silent-e, multisyllable decoding |
The 10-minute "where are we really" check
Skip the guessing — run our phonics assessment you can do at home a week or two before term. It tells you exactly which sounds are secure and which need a refresh, so your tune-up time goes toward the right things.
A simple 2-week tune-up plan
- Week 2 before term: run the home assessment, note 2-3 rusty sounds or patterns.
- Week 1 before term: 5 minutes a day on just those rusty spots — use the phoneme map for audio if a sound feels unfamiliar again.
- First week back: keep the daily habit going with our 5-minute daily phonics routine so the momentum doesn't drop again once school starts.
One more thing worth checking before term: our full phonics stages by age guide, if you want the complete developmental timeline rather than just the September snapshot.
