The question of knowing whether there are any really untestable autistic ch
ildren is attempting the impossible. Because of their pathology, these chil
dren do not follow the usual required norms, the established IQ's and in fa
ct, do not match the finality of the tools at the clinician's disposal. Mor
eover, the global nature of the scales sometimes hides the autistic child's
specificity, the heterogeneity of his profile and his abilities, which is
subsequently not conducive to therapeutic or educational care. For us, psyc
hological assessment must be adaptive to each child, repeated and constantl
y evolving and each interpretation must be finely tuned and above all, comp
lementary to other methods. In the face of clinical practice, research and
care, it is up to each clinician to choose the most relevant and adapted in
struments or scales according to the child in front of him in order to achi
eve the set objectives.
