The CNRep presents children with forty unfamiliar non-words ranging in syllable length from 1 to 4 syllables spoken aloud one at a time. The child is asked to repeat each word immediately after presentation. Correct scores are given for non-words pronounced correctly. Raw scores out of a possible total of 40 are recorded. The CNRep test was not administered to the first 300 children attending the CALM clinic. Closest-age matching was used to derive age-referenced scores for children outside the age-normed reference frame.
