High school achievement, or the lack of it, has been related to various non-intellectual variables, including personality and psychopathology as measured by personality inventories. The personality instruments chosen have typically been the Bernreuter, the Bell, and teh MMPI. Two studies (Finch, 1932; Sappenfield, 1938) found no relationship between achievement and adjustment as measured by the Bernreuter inventory. Two studies with the Bell inventory were contradictory, with a positive report by Resnick (1951) and negative findings by Griffiths (1945). Gough (1949) was unable to predict achievement from selected MMPI items. The present study was designed to clarify the status of the Bell Adjustment Inventory as a predictor of high school achievement.
