Background: The professional development (PD) of early childhood teachers is of strategic importance in higher education and the profession given the need to improve responsiveness and progress towards millennium goals. Aim: The purpose was to analyse classroom practices and teachers' experiences of PD programmes, through the theoretical lens of the UNESCO ICT Competency Framework for Teachers to construct an authentic data-based model, which can be used to understand PD challenges and guide decisions about the improvement of education quality. Setting: The study was conducted in Gauteng with teachers from a selection of early childhood centres. Methods: A phenomenological inquiry explored the settings and practices of 23 selected teachers in Gauteng province. Interview and observation data were analysed for content categories and grounded theory articulations. Results: The main finding is that teachers facing everyday educational challenges benefit from school-based support and available media but need additional learning to advance their professional aspirations. The grounded theory analyses of the data highlighted that early childhood practices and articulated development needs are best explained as authentic caring. This was conceptualised metaphorically as garden spaces where careful tending, deliberate planning and various elements of nurturing knowledge may harmoniously be blended. The model extends prevailing theories of PD and the flipped ICT Competency Framework for Teachers. Conclusion: The model of authentic caring is a grounded theory articulation based upon beliefs of practising EC teachers. Contribution: The article provides a comprehensive online teacher professional development framework for EC teachers, emphasising authenticity, care and alignment with global educational standards.
