What Retention Charts Cannot Show
Retention charts offer clarity that institutions understandably welcome. Lines rise or fall, cohorts persist or disappear, and progress appears measurable. Yet such charts describe motion, not education. They reveal who remains enrolled but say little about what students become. New approaches to data visualization suggest a corrective rooted in older academic judgment. Portfolio views show work accumulating over time rather than credits alone. Narrative dashboards reintroduce voice, reflection, and interpretation. Multi dimensional views allow cognitive growth, ethical reasoning, and practical skill to coexist without collapsing into a single score. These designs accept uneven development as natural rather than problematic. Education has always resisted tidy representation. Visualization should honor that complexity, not replace it with reassuring percentages.
