Pragmatics refers to the ability to effectively use and interpret language in different contexts. Pragmatic abilities develop and refine through childhood, and they are essential for socialization, academic achievement and wellbeing. The scarcity of assessment tools in this field makes it challenging to provide a comprehensive assessment of pragmatic abilities. The Pragma test, originally developed for Finnish and also adapted into Italian, consists of a battery of tasks assessing children's pragmatic abilities. In this study, a first evaluation of the psychometric qualities of a Norwegian adaptation of this test is presented. In addition, we investigated pragmatic development between ages 5 and 7, and explored possible gender-based differences. Altogether 119 Norwegian-speaking children participated in the study. The children were tested with the Pragma test and parents completed the Children's Communication Checklist-2. The children were allocated into three groups: 5-year-olds, 6-year-olds and 7-year-olds. The psychometric qualities of this Norwegian adaptation supported its use as a tool for assessing pragmatics in children aged 5-7. Strong and significant growth in pragmatic competence was observed from age 5-6, subsequently flattening out between age 6 and 7, and gender differences in favour of girls were identified. These findings indicate that pragmatic ability, as measured by the Pragma test, shows similar age effects in a Norwegian setting as in Finnish and Italian contexts, paving the way for further cross-cultural and cross-linguistic studies.
