The Bruininks-Oseretsky Test of Motor Proficiency (Bruininks, 1978) is a standardized, norm-referenced measure used by physical therapists and occupational therapists in clinic and school practice settings. This test recently was revised and published as the Bruininks-Oseretsky Test of Motor Proficiency, Second Edition (BOT-2; Bruininks & Bruininks, 2005). The BOT-2 is an individually administered measure of fine and gross motor skills of children and youth, 4 through 21 years of age. It is intended for use by practitioners and researchers as a discriminative and evaluative measure to characterize motor performance, specifically in the areas of fine manual control, manual coordination, body coordination, and strength and agility. The BOT-2 has both a Complete Form and a Short Form. This review of the BOT-2 describes its development and psychometric properties; appraises strengths and limitations; and discusses implications for use by physical therapists and occupational therapists.
