This symposium highlights recent international research on the Intelligence and Development Scales - 2 (IDS-2), a multidimensional tool for assessing children's and adolescents' cognitive and developmental functioning. The symposium addresses the scientific and practical relevance of advancing assessment practices in school, clinical, and cross-cultural contexts from pure reliance on IQ measures to multidimensional approaches. The symposium presents a breadth of perspectives: from understanding the requirements and opportunities of valid international test adaptations to innovative approaches for profiling strengths and challenges, linking cognitive abilities with emotion regulation, and developing new clinically sensitive indices of intelligence. Together, these contributions emphasize how the IDS-2 can provide evidence-based, culturally valid, and clinically useful insights that move beyond reliance on global IQ scores alone. The first contribution examines the rigorous international adaptation of the IDS-2. It highlights the balance between cross-national comparability and local cultural validity, showing how coordinated processes and collaboration with domain experts ensure robust test adaptations across languages and contexts. A second presentation provides evidence of factorial, convergent, and differential validity across six countries, demonstrating that the added value of combining cognitive and developmental measures is both valid and generalizable. In the third contribution incremental value of developmental profiles is being investigated through latent profile analyses, illustrating how multidimensional assessment refines educational decision-making. Building on this, another study examines how intelligence and executive functions predict emotion regulation strategies, highlighting the role of the cognitive profile in understanding youth mental health. Finally, the symposium presents the proposal of two new indices (Central Ability Index, Balanced Intelligence Quotient) to strengthen the theoretical and clinical sensitivity of IDS-2 intelligence measurement. In sum, the symposium showcases how the IDS-2 can advance psychological assessment by integrating methodological rigor, cultural adaptation, multidimensional profiling, and clinical innovation, thereby enhancing both scientific knowledge and practical application.
