With increasing calls for authentic assessment in higher education, the reference point for authenticity has been questioned. Typically, researchers define authenticity in relation to purposes of higher education, which are contested. Advancing the notion of educational authenticity rather than professional, societal, disciplinary, or developmental authenticity, we shift the reference point from outcomes to the process of meaningful student engagement. To illuminate features of educational authenticity in assessment, we surveyed students about their most interesting, engaging assessment and analysed 302 explanations why that assignment was so engaging. While many students cited real-world connections, consistent with most authentic assessment literature, more described having choice in some aspect of the assignment. We examined how choice, not typically a defining feature of authentic assessment, and real-world connection mattered to students and promoted meaningful engagement. Understanding and designing for educational authenticity can lead to various, valued outcomes highlighted in existing authentic assessment literature.
