Abstract
Strengthening the education of health professionals is imperative to effectively address contemporary public health challenges. Preceptorship, by integrating teaching and care within service settings, stands out as a relevant strategy for developing clinical, ethical, and relational competencies. This study aimed to construct a theoretical model based on the meanings attributed by nurse preceptors to preceptorship in pediatric nursing within the context of hospital-based training at a referral institute specializing in rare and complex diseases in Rio de Janeiro, Brazil. The study used Grounded Theory and Symbolic Interactionism as its methodological and theoretical frameworks, respectively, and involved interviews with 14 preceptors. The resulting model characterizes preceptorship as an interactive process materialized in pedagogical practices that integrate technical skill, empathy, responsibility, and creativity into the daily routine of care. The findings offer valuable insights for strengthening professional training programs in health and contribute to public policies that recognize preceptorship as a component of interprofessional education and of workforce development, with a focus on humanization, safety, and contextualized care.
