The present research attempted to modify Rest's Defining Issues Test (DIT) in order to better differentiate stage 6 moral reasoners from stage 5 reasoners. A review of the literature showed that the DIT seems to be both reliable and valid, yet it is unable to clearly differentiate between the stages of principled moral reasoning. After three pilot tests, newly developed stage 6 items were added to the DIT. The revised DIT was then administered to people believed to be stage 6 reasoners. Of the 30 respondents, three made the stage 6 cutoff. No stage 6 items were shown to clearly differentiate between stages 5 and 6.
