The Judgment of Line Orientation Test (JLO; Benton, Hamsher, Varney, and Spreen, 1983) permits assessment of visuospatial processing without making demands on motor skills. However, its administration can be time-intensive and frustrating for patients, particularly when used in a geriatric population. We present a single set of normative data to be used for both the odd-item and even-item forms derived from Form V of the JLO based on responses from a healthy geriatric sample. Mean scores and distributions of odd-item and even-item forms were nearly identical, and both forms showed significant correlations with the Developmental Test of Visual-Motor Integration. Cross-validation using the odd form of the JLO on an independent sample from a different geographic location suggested good generalizability of the normative data. We conclude that these JLO short-form normative data may be used in clinical screening situations or when serial assessments are needed.
