The United States Employment Service (USES) Specific Aptitude Test Battery (SATB) for Carpenter is evaluated from three points of view: (1) technical adequacy of the research; (2) fairness to minorities; and (3) usefulness of the battery to United States Employment Service staff and employers in selecting individuals for Carpenter positions. Research demonstrated a statistically significant and useful relationship between proficiency as a Carpenter and the SATB. The SATB can be expected to produce a useful increase in the proportion of highly proficient workers. When the SATB was applied to the validation sample, composed of individuals who were employed and therefore considered competent, an increase from 66 percent to 82 percent in the proportion of highly proficient workers was found. Similar results were found for the cross-validation sample. A greater increase can be expected when the battery is used with applicants, because the range of relevant abilities is wider among applicants than among employed workers. The report includes: (1) research summary; (2) procedure; (3) analysis; and (4) validity of the battery. Descriptive statistics for subgroups of the validation sample; descriptive rating scale; and job description are contained in the appendices. (Author/PN)
