Abstract
30 elementary school pupils in grades 2 to 6 were given 2 tests each containing 100 consonant items, identical except for the position of the consonant element or combination. In the 1st test, the consonant was in the initial position and in the 2d, in the final position. When consonants are in the middle or final position, children make more errors in discrimination between consonants. Such a short test is effective and statistically reliable.
