Selected items from various forms of the original Benton Visual Retention Test (BVRT) were used to construct two parallel forms with 20 items in each form. The extension of the test has improved its reliability, often criticized as being too low. By enhancing the reliability, we improved the sensitivity of the test for impairment, however the specificity remains unchanged in the revision. We examined the impact of age and education on the BVRT test scores. The modified forms were standardized for four age groups between 15 and 70 years. Based on the results of a Rasch analysis, we suggest that the administration of the revised BVRT may be discontinued after four consecutive failures without any serious effects on the test score.
