Speech sound disorders (SSD) are associated with difficulties in communication, social participation, literacy, and learning. An early identification process is therefore necessary. Our study was aimed at determining the utility and accuracy of parent's and teacher's concerns in screening for SSD. We also aimed to determine whether the accuracy of parent's and teacher's concern varied according to kindergarten grades. For this study, 215 French-speaking preschool children were recruited from preschools. Eighty children were classified as SSD and 135 were classified as Typically Developing (TD). Children were assessed by a standardised single-word speech sound test. Parents and teachers expressed their level of concern about each child's speech development by answering 'no', 'a little' or 'yes' to the same question about their concern. Parents' and teachers' concerns were also gathered in a variable called 'joint concern' to investigate the utility and accuracy of their combined concern. Analyses included tetrachoric correlations, logistic regressions, Kruskal-Wallis tests, and sensibility/specificity analyses. Analyses were employed across all children and within age groups. Results showed positive and significant correlations between the SSD-TD classification, parent's concern, teacher's concern and joint concern. Parents' and teachers' concerns both showed fair specificity rates (85.2% and 88.1%, respectively) but remained under 80% on sensitivity. The joint concern was the most sensitive measure of all (87.3%) but showed a low specificity rate (76.3%). In conclusion, parents' and teachers' concerns both emerged as useful measures for screening for SSD. The combination of their concern revealed how parents and teachers are complementary for SSD screening.
