A new framework called PEARL has been developed to rigorously evaluate differentially private synthetic educational data. PEARL ensures that synthetic datasets not only meet privacy standards but also remain useful for specific educational tasks, such as dropout prediction or knowledge tracing. In extensive testing across 96 settings, only a small fraction of datasets passed all PEARL checks, highlighting significant challenges in generating synthetic data that balances privacy with predictive accuracy and fairness across different student groups.
