Locus of control is fairly stable over time but does change as a result of natural events, such as the acquisition of college education. Previous research found this to be so in a study of the high school class of 1972. This investigation asked whether a model of stability and change in locus of control had changed since the benchmark study of the 1972 high school class. Using a carefully designed structural equation model comparing high school classes of 1972 and 1992, we concluded that the influence of college on locus of control, although small to begin with, has not changed in 20 years.
