Abstract	The purpose of this paper was to examine the psychometric properties of a non-word repetition task (NRT), the Late-8 Non-word Repetition Task (L8NRT). This task was designed similarly to the NRT, but contains only Late-8 consonants to increase articulatory demands and avoid ceiling effects in studies with adolescents and adults. Thirty college students were administered the Woodcock Reading Mastery Tests-Revised/Normative Update WRMT-RNU, L8NRT and NRT. Results showed that inter- and intra-rater reliability of the L8NRT were high; split-half reliability was significant and comparable to that of the NRT. Average L8NRT scores were significantly lower than NRT scores overall and at all non-word lengths but the shortest (1 syllable). Both measures correlated significantly, at similar levels, with Total WRMT-RNU score. We conclude that the psychometric properties of the L8NRT were acceptable, but an error analysis suggested ways in which the task might be improved to better control perceptual demands and articulatory feature overlap.
