This paper outlines a new approach to cultural awareness training, the Individual Differences Approach to Diversity Awareness (IDADA). IDADA is distinguished from other approaches in three ways: (a) it eliminates the need to characterise cultures, (b) it addresses unfair discrimination of any kind (e.g., weight, height, attractiveness), (c) it teaches employees to become aware of how their attitudes affect organisational performance, and (d) it focuses on job requirements. Initial evidence supports the validity of the model. The paper also introduces a new measure of diversity-openness called the Ideal Employee Inventory. Preliminary reliability and validity evidence for the measure is provided.
