This study represents an attempt at incorporating empirical item difficulty data into the Angoff standard-setting procedure without affecting the subjective judgment of the raters. The Rasch-model ability level corresponding to minimal competence was estimated for each of 536 items on the American Association of State Social Work Boards (AASSWB) social work licensure examinations from their empirical calibrations and Angoff ratings. The mean of these estimates for all items on a given examination was taken as the level of minimal competence for the entire examination. This procedure yielded raw parsing scores that were 4 to 6 items lower (out of 150) and pars rates that were 7% to 15% higher than those obtained using the ''standard'' Angoff procedure.

Increasing concerns regarding the cost of medical care have led to research that has found a relationship between alcohol abuse, increased medical problems, longer hospital stays, and higher medical costs. Research has also found a positive relationship between alcohol availability and crime, car accidents, and liver cirrhosis deaths. One area of interest is how alcohol availability, as measured by the number of alcohol outlets, is related to medical care needs. The purpose of this study was to examine the relationship between the geographic density of alcohol outlets and the number of alcohol-related hospital admissions. alcohol-related ICD-9 codes were selected based on epidemiologic research in the literature to determine alcohol-related morbidity from the California Discharge Data System, which collects information on all hospital admissions and discharges in California. In San Diego County, in 1996, 3,759 admissions were alcohol-related. Alcohol-related admissions for each zip code were compared to the number of liquor licenses that were held by each zip code through a multiple regression analysis. The regression model demonstrated that the number of liquor outlets was a significant predictor of alcohol-related hospital admissions, net of other predictors. Implications are discussed, including regulation of alcohol availability, which may have a beneficial impact on alcohol morbidity.

A correlation of .80 was obtained between mean national licensing examination score in 1988-1995 of graduates of clinical programs and mean score of these programs in 1997. It was maintained that this stability over time strengthens the inference that this mean score is a good index of program quality.
