Construction and Administration of Experimental Medical and Chemical Information Items for the ACB

摘要

Research to maintain and improve tests in the Army Classification Battery (ACB) includes the development of information items that measure aptitudes required for medical and chemical MOS. Assignment to medical MOS is based on scores obtained in the General Technical (GT) Aptitude Area, and assignment to chemical MOS is based on scores obtained in the General Maintenance (GM) Aptitude Area. GT is composed of two measures (Verbal and Arithmetic Reasoning) which are highly loaded in general intellectual ability. GM is composed of a general intelligence measure (Pattern Analysis) and a broad mechanical measure (Shop Mechanics). The latter is scheduled to be replaced by a more specific measure related to particular mechanical specialities. New test content (items measuring medical and chemical information) is required to improve differential classification in these aptitude areas.
