Standardized training, the full name of standardized training for residents, belongs to the content of re-education after graduation and is a policy formulated by the state to standardize the clinical level of residents and improve their clinical ability. General medical undergraduates graduate for three years and master students graduate for two years. Doctoral students need to go to the standardized training base for residents for one year. After the training, standardized training theories and skills should be assessed, and training certificates can only be issued if the results are qualified.
