This test is intended as a problem-solving tool for adults seeking to teach spelling in a systematic, explicit way. It is not a standardised test, nor a substitute for standardised testing.
The main aim is to help you explore which spelling patterns and word structures learners know, and which they don’t, and thus be able to focus on teaching the patterns they don’t know yet, and not waste time teaching patterns they already know.
Don’t ask children to do the whole test, just start where you’re fairly confident the child can get most words correct, and work forwards if they do indeed get them correct, or backwards if not. Stop when they’re getting most words incorrect (if going forwards) or correct (if going backwards). Help them practise the patterns on which they made errors.
This test might also help adults organise their thinking about spelling/word structure, and the influence of sounds (phonemes), spelling patterns (graphemes) including position in words, meaningful word parts (morphemes) and word origin (etymology) on spelling.
