Setting a standard on the pilot National Board Dental Examination.

Norm-referenced and criterion-referenced approaches to setting a standard, or minimum passing score, were used with the pilot Part II National Board Dental Examination. The criterion-referenced approach used with the pilot is based on the Rasch measurement model. The standards and associated failure rates were found to be similar for both approaches. These findings as well as the advantages associated with using the Rasch model suggest that this criterion-referenced approach to setting a standard on the restructured Part II examination is appropriate.

Reliability and validity of the pilot National Board Dental Examination.

The reliability and validity of the pilot National Board Dental Examination were examined. The results indicate that the pilot examination is a reliable test that assesses a full range of cognitive behaviors. Furthermore, the findings indicate that the pilot examination is a unidimensional test of comprehensive general dentistry. The performance of examinees on the pilot examination was found to be similar to their performance on the traditional Part II examination. These findings suggest that the restructured Part II examination will be a more reliable and valid measure of dental students' knowledge and problem-solving skills than the traditional Part II.

Dental student attrition.

In summary, the attrition rate for the recent dental school freshman classes has been reduced to 3 1/2 %. The national freshman enrollment of US dental schools can be expected to have approximately a 7% attrition rate by the time of graduation. The reasons for student withdrawal are evenly divided between personal and academic problems. The academic problems are experienced with slightly more frequency in nonclinical courses than in technique courses, both areas of difficulty being predicted significantly by DAT scores. Finally, the attrition rate for women is higher than for men, which has been true to a significant degree in the first-year classes during the past two years, as well as for all four years of dental school. However, no specific reason has been identified for this difference.

Continuing education in US dental schools.

This information provides a rudimentary profile of continuing dental education in US dental schools. Some schools have wide-ranging, time-tested programs, whereas others have initiated programs only recently, yet over half of the schools mentioned that there still was an unfilled need for continuing dental education in their locality. To meet the need for quality programs in the future, the great majority of the schools (49) indicated that, although the nature and level of evaluation was open to discussion, a program of accreditation or evaluation is definitely necessary and should be implemented in the future.
