Societal Impact Statement Plant biology is an essential discipline for addressing global challenges from food security to climate change. In order to achieve this, we need to educate plant biologists who can contribute to research, enterprise, policy, public engagement and beyond. This article explores the potential of competency‐based education, which emphasises what students can do rather than what we know. A flexible and adaptable model of competency based plant biology education is presented, along with practical suggestions and examples. This provides a framework through which we can educate plant biologists equipped to address major scientific and societal challenges of the future. Summary Plant biology is an essential discipline for addressing global challenges from food security to climate change. In order to achieve this we need to educate plant biologists who can contribute to research, enterprise, policy, public engagement and beyond. In this article, I explore some of the issues and challenges facing plant biology education from authentic research driven curricula to the impact of AI. In order to effectively educate the plant biologists of the future I propose moving to a competency based approach to education. Competency based education emphasises what students can do rather than what they know. I present a three‐domain competency model for plant biology, structured around (i) knowledge and information literacy (ii) disciplinary and professional experience and (iii) self‐awareness and personal development as three interdependent aspects of competency. I accompany this with twelve proposed competencies for plant biologists. The model is flexible, robust and adaptable to specific local requirements and future demands of plant biology education. In reimagining plant biology education in this way we can present our discipline as exciting and relevant to students, and equip them with the capabilities required to contribute to plant biology activity from research to public policy.
