Objective To set up a standardized examination system for clinical internship at the de-partment level

and to evaluate the system using educational measurement method. Methods All the 327 clinical five-year and eight-year intern trainees who took clinical internship in the spinal orthopedics de-partment of a teaching hospital from July 1

2014 to June 30

2016 were selected as the research subjects. All the subjects took the standardized examination

educational and measurement methods such as general descriptive analysis

project relevance analysis and grader consistency analysis were executed to assess the content validity of the system

the relevance of the project and the consistency of the scorers. Statistical calculation was executed by SPSS 23.0 software. Results The average score of all 312 trainees included was controlled at (80.07±4.67)

the lowest score was 70.01

and the highest score was 90.01

which reflected that the overall difficulty was moderate

the difference was reasonable and the scores were evenly distributed. To the theory

skills

medical records

teachers' score and the reward plus

normalized regression coeffi-cients were 0.479

0.473

0.118

0.135 and 0.364 respectively

which were in good agreement with the scores of each item in the total score. To the theory

skills and teacher evaluation

the analysis of variance of the total score showed that the P values were both ≥0.05 with no significant difference between the groups

so the consistency of the scorers were satisfactory. The P values of variance analysis of the two items of the medical record and bonus points were 0.000 and 0.002 respectively

with significant differences among the groups

the scorers were less consistent. Conclusion The standardized examination system can meet the requirements of comprehensive

full-scale

quantitative and stable feedback teaching effect. The system of internship practice examination must be able to withstand continuous implementation and repeated correc-tion over many years

so as to ensure the teaching quality.
