At the present time, no screening test in French exists to identify children at risk of auditory processing disorder (APD). Children with APD are known to experience more difficulties in processing auditory information than typical developing children, especially in noisy environment. At school, some have problems with several subjects. The objective of the present pilot study was to create a tool to screen children who might have APD. This type of test could be helpful to identify children who need a complete audiological evaluation to rule out or to confirm a diagnosis of APD. Twenty-one 7-13 year-old children participated. They had normal hearing thresholds between 250 and 8000 Hz in both ears and no known neurological disorder or intellectual disabilities. The screening test was composed, in part, of four clinical behavioral tests for which the number of items were shortened for three of them. Those were 10 (instead of 20) of two-pair dichotic digits, 10 syllables (instead of 35) presented in a babble noise in each ear, 15 (instead of 30) sequences of three pure tones; one has a different frequency than the two others. The sequences were sent monaurally. Finally, a digit memory span test was used. Children were assessed first with the screening test and then progressed with the clinical auditory processing test battery. Out of the 21 participants, only three failed the screening and the clinical tests. All of these three participants failed the dichotic listening test, two failed the frequency sequencing test and only one failed the speech in noise test. Based on these preliminary results, among the auditory tests used, the dichotic listening test might be the most sensitive as a screening test to refer children for a full APD clinical assessment._x005F_x005F_x000C_
