Age-specific competencies refer to skills that allow nurses to provide care tailored to a patient's unique needs based on their age and stage of development. There are eight major life stages: infant, toddler, preschooler, school-age, adolescent, young adult, middle-aged adult, and older adult. Each life stage is associated with specific physical and psychosocial characteristics that should inform how nurses communicate with, assess, educate, and provide care for patients of different ages. Understanding age-specific competencies is key to delivering patient-centered care.
