Clinical supervision is an essential component of psychotherapeutic practice. However, the literature suggests that the provision of supervision in the public sector has been declining significantly over the past two decades, suggesting that many health care professionals are receiving neither the guidance nor support needed to deliver safe and effective care. Identifying the distinct challenges of supervision in the public sector and proposing prospective solutions is, therefore, a burning issue. In this article, we introduce a novel analytical framework for clinical supervision-the MATRIX-striving to address the unique demands of psychotherapy in the public sector. Various applications of this framework are thoroughly presented and further exemplified using a case illustration. We conclude by discussing the contribution of MATRIX-aided supervision to the acquisition of expert performance in psychotherapy, while also addressing its limitations.
