What Is the Horizontal Scoring System?

The Horizontal Scoring System is a rank-order scoring method by Gordon and Cochetti (1980s). All responses within each channel are ranked by magnitude; ranks for comparison questions receive positive values, relevant questions negative values. The method is used with the IZCT but may be limited to single-issue testing. Some criteria lack empirical support.
