Written against the backdrop of the 2020 twin pandemics of a global health crisis and greater national awareness of structural racism, this article issues a call for psychology to invest in training all psychologists to respond to the social ills of racial and other forms of oppression. We introduce a public psychology for liberation (PPL) training model. Essentially, the model reflects a science, a pedagogical commitment, and practice of, by, and with the people who have been most marginalized in society. The PPL consists of five foundational domains or cross-cutting areas of expertise (e.g., facilitate human relationships; generate reciprocal knowledge and translation) and 10 interrelated lifelong practices (e.g., cultural humility; care and compassion) that foster healing and equity. The model centers the perspectives of the Global Majority, focuses on radical healing and equity, and emphasizes a developmental, culturally grounded, strengths-based approach to training. Various training initiatives consistent with a public psychology for liberation approach are presented. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
