Italian Ministry of Education GPS algorithm mis-ranks thousands of teachers
The Italian Ministry of Education's GPS automated allocation system for short-term teachers suffered a critical logic failure. Thousands of eligible teachers were wrongly excluded from assignments, resulting in lost income and numerous lawsuits.
The algorithm classified discarded teachers as drop-outs, ignoring the possibility of matching them with new vacancies.

What happened
The Italian Ministry of Education's GPS automated system for allocating short-term teachers mis-ranked and erroneously excluded thousands of candidates from recruitment. This failure led to wrongful assignments and thousands of teachers losing their pay, sparking widespread legal appeals and intervention by trade unions.
What broke inside the model
- 01 · TriggerAn agent plans a multi-step task.
- 02 · Model stepIt chooses a wrong or destructive action.
- 03 · Control gapNo confirmation gate guards the write.
- 04 · FailureThe action commits to a system of record.
- 05 · ConsequenceData is changed or destroyed irreversibly.
A wrong action commits, and the step is written before anything can stop it.
The algorithm failed to reset the list of remaining candidates after filling a vacancy. Consequently, candidates who missed out on an initial match were permanently classified as drop-outs and discarded from the pool for all subsequent vacancies.

This entry sits in the index's predictive wing: a system that scores, ranks, perceives, or steers rather than generates. Realm's runtime layer is built for the generative and agentic systems now moving into these same decision seats, where it watches a model's internal state and holds an unsupported claim or an unchecked action before it commits. The control gap on this record, an automated decision that reached people with no runtime check in front of it, is the same gap. The index keeps predictive failures on the record because the pattern carries straight into the systems shipping today.
