Early in their career, occupational therapists may require a range of additional development for a successful transition to the profession. However, both the definition of 'early career' and the relevant development for this career stage vary between sources. In regard to occupational therapists transitioning to mental health professional practice, there is very little evidence to draw upon when designing the structure and content of development programs. This study aimed to review current practices in early career programs for mental health occupational therapists within the Australian state of Victoria. Tertiary mental health services in Victoria were purposefully recruited, supplemented by snowball recruitment. The participants responded to a bespoke survey including open and closed questions, designed to benchmark practices against previous research and explore current practices with early career mental health occupational therapists. Thirteen services participated, with respondents including senior clinicians, allied health chiefs, allied health clinical educators and early career development program coordinators. The participants confirmed the perceived value of development programs for early career mental health occupational therapists; however, limited resources were available to develop, implement and sustain these supports. Program content, structure and terminology varied significantly, as did the identified competencies for participants to achieve. Some of this variability was related to program eligibility criteria and early career workforce structure within organisations. Early career mental health occupational therapist development should be responsive to their local service environments. A better understanding of the outcomes of these programs for early career occupational therapists, from both an individual and service perspective, could also provide a firmer rationale and foundation for sustained resourcing of this valuable approach to workforce development.
