We found that a minority of children (12%) with
ASDs performed below the normal range on this
standardized test of articulation, although the percentage
of children producing a small number of
errors was much higher than this (41%). Unlike
previous studies of larger groups of children with
ASDs, we analysed the types of errors made by the
children. Most errors were developmental in nature,
suggesting a pattern of delayed speech, although
the fact that GFTA-2 scores were not correlated
with scores on other language tests suggests that
the delayed speech may not be part of an overall
language delay.
