The challenges observed in health-service-psychology (HSP) training during COVID-19 revealed systemic and philosophical issues that preexisted the pandemic but became more visible during the global health crisis. In a position article written by 23 trainees across different sites and training specializations, we use lessons learned from COVID-19 as a touchstone for a call to action in HSP training. Historically, trainee voices have been conspicuously absent from literature about clinical training. We describe long-standing dilemmas in HSP training that were exacerbated by the pandemic and will continue to require resolution after the pandemic has subsided. We make recommendations for systems-level changes that would advance equity and sustainability in HSP training. This article advances the conversation about HSP training by including the perspective of trainees as essential stakeholders.
