The study determined the significant relationship between self-concept and skills competency of 44 Alternative Dispute Resolution (ADR) Accredited Supreme Court Mediators in the 11th Judicial Region. Based from the findings, policy enhancement related to alternative dispute resolution was created. Using descriptive correlational method, validated questionnaires, mean, t-test, ANOVA and Pearson r, results showed that mediators have high level of self-concept and very high level of skills competency. Significant relationship existed between self-concept and skills competency. It is recommended that educational trainings and other intellectual transformative undertakings may be regularly conducted. The proposed University of Mindanao policy on the selection of alternative dispute resolution mediators may be given due consideration by administrators. Replication of this study may be undertaken involving College of Law and other colleges of the University as a way of evaluating practitioners.
