Judge not, that ye be not judged. For with what judgment ye judge, ye shall be judged: and with what measure ye mete, it shall be meted to you again. (Matthew 7:1, 2)·This article consists of a step by step refutation of criticisms made by Dr. Hans Jellen in a presentation entitled "Renzulli-it-is: a national disease in gifted education" delivered atthe Illinois State Conference on the Gifted, on 14th November 1983. The threering conception of giftedness (abilities, creativity and task orientation) is justified and supporting research is quoted. The Student Product Assessment Form (SPAF) is defended and compared to Jellen's unadapted S1U 0-100 Approach, and the widely adopted Enrichment Triad Model for developing programmes for the gifted is compared to Jellen's entirely untried "more-of-the-same" approach.
