Assessing Intellectual Development: Three Approaches, One Sequence

In this paper, I compare three developmental assessment systems, employed to score a set of 152 interviews of engineering students: the Perry Scoring System (W. G. Perry, 1970), the Hierarchical Complexity Scoring System (T. L. Dawson, 2004, 1/31/03), and the Lexical Abstraction Assessment System (LAAS; T. L. Dawson & M. Wilson, in press). Overall, the Hierarchical Complexity Scoring System and Perry Scoring System agree with one another within the parameters of interrater agreement commonly reported for either one of the systems, and the Perry system and the LAAS agree with one another about as well as the LAAS and the Hierarchical Complexity Scoring System, upon which the LAAS is based.
