NLP analysis of clinical documentation provides a scalable, detailed method for tracking EM residents' clinical exposure and progression.

These findings suggest that a 4-year training model may offer meaningful additional educational value, while also highlighting the importance of individualized assessment given the variability in learning trajectories.
