[Investigation on the affinity between questions in the national examination for medical technologists and student level of education in the course of laboratory medicine--nine years history of the committee evaluating appropriate questions].

In order to evaluate the each question in the National Examination for Medical Technologist by comparison with the educated level in the course of laboratory medicine and the practical level of medical technologists, the investigation has been carried out by our committee established in the National University Association for Education of Laboratory Medicine during 9 years since 1997. The committee has asked each school of the 20 members of the Association to pick up good and/or inappropriate questions with the reasons why they are classified as good or improper ones. Some questions were considered as good ones by a large number of schools, while the others were considered improper. The reasons for the judgment have been sometimes very controversial and opinions uncommonly run counter to each other. It is suggested that a good question may become to be improper when the questionnaire is carelessly arranged even if the concept of the question is initially well considered. It is presumed that the annual reports of our committee may have played a role to gain common recognition that the numbers of the inappropriate questions have been decreasing in the recent National Examination for Medical Technologist.
