Background <p>Lung ultrasound is a valuable tool for pediatricians, aiding in diagnosis and procedural safety while reducing radiation exposure. Its application has significantly increased. However, unlike some other medical specialties, structured ultrasound training is not consistently integrated into pediatric residency programs, resulting in variable skill acquisition among national practitioners. This lack of standardization necessitates the development of a comprehensive educational framework.</p> Main body <p>A standardized, longitudinal core curriculum for pediatric lung ultrasound is developed through a consensus of nationally recognized experts. The proposed model defines progressive proficiency levels, each with specific clinical competencies, skills, and measurable milestones. An integrated assessment strategy, combining written examinations and objective structured clinical examinations, is recommended to evaluate both theoretical knowledge and practical application. Furthermore, the curriculum outlines a hands-on practical pathway, requiring supervised clinical procedures and tutor validation at each proficiency level. The article also addresses key challenges hindering the widespread adoption of curricula in pediatrics, including a shortage of qualified instructors, limited access to resources and training time, and the need for robust quality assurance measures and standardized image interpretation protocols.</p> Conclusion <p>The proposed core curriculum offers a structured educational platform to promote the systematic acquisition of lung ultrasound skills among pediatricians. Addressing the identified barriers is essential for the successful integration of lung ultrasound into pediatric clinical practice, ultimately improving diagnostic accuracy and enhancing patient care.</p>
