Real-Time Student Performance Dashboard API with GraphQL

Design a GraphQL API using Python and Graphene that aggregates student performance metrics from multiple learning management systems (LMS). Create resolvers that can dynamically fetch and combine grade data, engagement metrics, and learning progress across different educational platforms. Implement authentication using JWT that allows granular access control for administrators, teachers, and students, with role-based data visibility. Include complex query capabilities to support advanced analytics like comparative performance tracking, predictive learning intervention points, and personalized curriculum recommendations.
