The authors state in a very condensed and compact paper, the following observations on the Roschach Test: (1) that it is beyond doubt the most potent single diagnostic instrument clinical psychology possesses; (2) that as an exclusive basis of diagnosis the test has serious limitations and its real potency is exploited only when used as the center of a battery of tests; (3) that the literature on the test can be used as a simple tool, and skill in handling it may be easily acquired, although its efficient use requires psychological and clinical knowledge, understanding and versatility.

The best attitude and procedure during the testing process is passivity. Extensions and refinements of the test tend to make it cumbersome, time consuming and prohibitive for clinical use.
