The aim of the study is to design a model for the development of creativity in primary school students in Tehran. The research method is applied in terms of its objective, qualitative in terms of data type, and a systematic grounded theory (paradigmatic) approach in nature. The target population of the study includes experts in the fields of educational sciences and psychology. Using a purposive sampling method of the theoretical type and based on theoretical saturation, 15 experts were selected for interviews. The research instrument was a semi-structured interview, during which the dimensions, components, and indicators of the model for developing creativity in Tehran’s primary school students were outlined. Initially, in-depth interviews with the experts were conducted to develop the interview form. Subsequently, open coding was used to extract the indicators, which were categorized into components and indicators using axial coding. The identified components and indicators were then sent to 15 experts for further analysis through selective coding, interviews, and brainstorming sessions. Consequently, the model was finalized with 5 dimensions, 16 components, and 102 indicators for fostering creativity in primary school students. After final validation and prioritization by the experts, the dimensions, components, and structural indicators of the model were drawn and revalidated by the experts.
