This study aimed to analyze the perception of speech in noise in children with poor school performance and to compare them with children with good school performance, considering gender, age and ear side as variables.The intelligibility of speech was evaluated in school children utilizing the Brazilian Hearing in Noise Test (HINT) in the situations of quiet (Q), Left ear competitive noise (NL), Right Ear Competitive Noise (NR), as well as the global average of other hearing situations, denominated Noise Composite (NC). Ninety seven school children between the ages of 8 and 10 were recruited in five schools of São Paulo-Brazil; the control group (CG) consisted of 54 students (23 male/ 31 female) without language and/or speech difficulties and good school performance, and the study group (SG) consisted of 43 students (28 male/ 15 female) identified by their teachers as having poor school performance.The variables gender and ear side did not interfere in speech perception. The age variable influenced only the CG. The SG had worse performance than the CG in the Q, NF and NC conditions. NF was the most difficult for both groups.The perception of speech in noise was the worst in children with poor school performance. The variables gender and ear side did not interfere in speech perception. The age group variable influenced the performance of the group of children with good school performance, demonstrating a better ability in older children. The speech perception in noise ability is more difficult for both groups when the noise affects both ears.
