What is The Children's Test of Nonword Repetition (CN Rep)?
The Children's Test of Nonword Repetition (CN REP) is suitable for use with children between 4 and 8 years who are attending mainstream schools and can also be used for older children with language related learning difficulties.
CN REP provides a reliable indicator of short-term memory which correlates well with language and other difficulties. The easy to use tables supply standardised scores and centile points for ages four, five, six, seven and eight years which are derived from a sample of 612 unselected children attending primary schools in England.
Why is there a need for CN REP?
Failure of children to progress readily through key areas of the primary curriculum is probably the most serious and most common problem faced by teachers and educational psychologists.
A common observation is that many of the children who are experiencing difficulties in English and reading have difficulties in remembering spoken language for even short periods of time. This often manifests itself as the apparent inability of a child to attend to and carry out simple instructions.
The most widely used technique of assessing a child's short-term memory has been the digit span task. Unlike other measures, CN REP has been developed using unfamiliar spoken words which the child must attempt to repeat.
The results have shown that this test is even more closely linked to important abilities such as vocabulary knowledge, understanding of spoken language and reading achievement than the digit span.
Features of CN REP include:
- The test performance provides a better predictor than digit span of children's later achievements in the key curriculum areas of English and reading.
- Because the test uses unfamiliar spoken items which are not part of the English language, it does not disadvantage children with a less rich environmental experience of language.
- It is rapid to administer and easy for children to understand.
- It has excellent correlation with later school performance.
