The purpose of this study is to analyze the most effective basis for assessing the intellectual capital maturity based on the themes of the ambidextrous learning link. In terms of purpose, this research is part of developmental research. Because of the lack of a basis for assessing the intellectual capital maturity under ambidextrous learning in previous research, based on meta-synthesis in the first step, an attempt was made to identify components as the analytical basis of the research and propositions as reference variables. Then, in order to explain the identified components and propositions, in a small part, intuitive fuzzy sets (IFSs) was used to determine the most effective basis for evaluating the intellectual capital maturity based on the themes of the ambidextrous learning link. In this study, the target population consisted of two parts: qualitative and quantitative. In the qualitative section, with the help of 16 management specialists and experts, an attempt was made at the university level to identify research components and propositions in the form of score forms. In the small section, 50 managers, officials and experts at various levels of knowledge-based companies participated. The results showed that the proposition of strategic tendencies in learning is considered as the most influential themes of the ambidextrous learning link in the studied companies, which strengthens the sustainability of knowledge creation as an effective component in the intellectual capital maturity.
