The preliminary phases of this study were the development and validation of an instrument which examines their competence on action research AR , and clustering them based on the similarity of their responses through Hierarchical Cluster Analysis. The factor analysis in instrument development yields five competencies in conducting AR, namely: a problem identification, b data collection, interpretation, action, and reflection, c appropriate use of data collection tools, d application of technology, and e research ethics which total percentage of variance explained is Meanwhile, the Cluster Analysis created two clusters of teacher-researchers. However, these levels still indicate recalibration of competencies to both clusters.
