The Battery consists of nineteen different work samples. Each work sample is timed to measure the speed with which the individual is able to do a series of similar tasks. The individual's score on each work sample establishes whether a particular task is more or less easy for that individual. Shown together on a personal profile and bar chart, the scores achieved by each individual reveal patterns or "clusters" of abilities which require analysis by a skilled interpreter. Once these patterns or "clusters" are understood, the individual is helped to guide his life and work into more productive and satisfying channels.
