School dropout ER model maps nine interconnected entities capturing family income, work necessity, academic performance, motivation, family problems, and socioeconomic factors that influence student attrition. Data flows from Ingreso Familiar through Necesidad de Trabajar to Desercion Escolar, with branches tracking Bajo Rendimiento, Falta de Motivacion, and Problemas Familiares as contributing factors. This relational schema enables education institutions and researchers to analyze root causes of dropout and design targeted interventions. Fork this diagram on Diagrams.so to customize entity attributes, add additional factors, or export as .drawio for integration into your education analytics platform. The model demonstrates best practices for capturing multifactorial social phenomena through normalized relational design.
