The United States Employment Service (USES) Specific Aptitude Test Battery (SATB) for Gambling Dealer is evaluated from three points of view: (1) technical adequacy of the research; (2) fairness to minorities; and (3) usefulness of the battery to Job Service staff and employers in selecting individuals for training as Gambling Dealers. Research demonstrated a statistically significant and useful relationship between proficiency as Gambling Dealer and the SATB. The SATB can be expected to produce a useful increase in the proportion of highly competent workers. When the SATB was applied to the validation sample, composed of individuals who were employed and therefore considered competent, an increase from 65 percent to 70 percent in the proportion of highly proficient workers was found. A greater increase can be expected when the battery is used with applicants, as the range of relevant abilities is wider among applicants than among employed workers. The report includes: summary; procedure; analysis; and the validity of the battery. Descriptive statistics for subgroups of the validation sample, descriptive rating scale for trainees, special and standard descriptive rating scales, job duties, and a training course outline are contained in the appendices.
