Mean length of utterance (MLU) of children with Down syndrome was examined and found to correlate highly with chronological age, r = .87, p less than .001, despite the children's language delays. The correlation was reliable at least up to MLU 3.00. In the 1.00 to 3.50 range, MLU also predicted grammatical complexity.
