Background.-This research aims to register predictive tests of reading
by way of a first intention test usually proposed in children with sc
hool difficulties: the WISC-R. Population and methods.-Thirty-one chil
dren aged from 3.9 to 8.3 years, consulting in a psychiatry service fo
r school difficulties, were tested twice. Twenty-one children aged les
s than 5.9 years (age for beginning to read), consulting for anticipat
ed schooling, were also included in the study. These fifty-two childre
n passed twice WISC-R for the elder and WPPSI for those who were young
er. Results.-Three subtests, similitude test, understanding test and t
est of Kohs' blocks seemed to be good predictive markers of ability to
read. Predictive score for fiability with these three tests was 87%.
Conclusion.-These tests that bring the ability of generalizing into qu
estion, as reality and space adjustment, show well the necessary quali
ties for a child who must begin to read.
