Research institutions typically rely heavily on the ability and performance of researchers who may works within various disciplines. As the current researchers are aging and will retire at some point in time, the institutions must have prepared their junior researchers to continue the research work. Previous literatures have proposed and defined the concept of Knowledge Management (KM) in order to meet the goal. However, the implementation of KM in an organization is not easy. The initial step is to take measurements of the degree of readiness of the organization to implement a detailed and comprehensive KM. Thus, this study is to assess KM readiness level of BATAN, a research institution in Indonesia. The KM readiness framework was validated by 3 experts, weighted by 8 experts using the Analytical Hierarchical Process (AHP) and processed using 151 respondent data. The analysis showed that KM readiness in BATAN has reached level 4 (receptive) which means BATAN is ready to implement KM.
