This paper highlights the reflective experiences of five graduate students who emerged as practitioner-scholars in the field of technical and professional communication (TPC) through their participation in the Spring 2025 graduate course, Writing Grants and Proposals, at Sam Houston State University. The semi-simulated, Better Sam Program assignment, grounded in a community-engaged and social justice framework, required students to develop unsolicited full proposals addressing local issues or opportunities within SHSU or the Huntsville community. This assignment challenged students to align their proposals with community needs while engaging in ethical, research-driven practices. Drawing on extensive community engagement, students developed proposals that were not only realistic and contextually grounded but also reflective of broader social justice concerns. The reflective process, guided by structured questions, encouraged students to critically analyze their proposal development experiences and consider the broader implications of their work for community advocacy and social responsibility. This paper presents these reflections, offering insights into how grant writing can be a transformative educational experience that fosters critical thinking, ethical engagement, and social impact.
