Abstract

The purpose of this research employs concepts of control charts to establish a new evaluation standard for a test quality index. First, this study establishes criteria for assessing test quality by exploring the item discrimination index (D) in the general test areas. Further, data of this one index are normalized, and standard deviation is applied for the control limit of the control chart. Thus, the zone rules for the standardized D (SD) control chart proposed in this study are found to be an excellent evaluation method for test quality from the perspective of control charts.
