'We often use Hogrefe questionnaires in our assessment centres for selection purposes. We appreciate the robustness of factor structure, the construct validity, and that reports are clear and versatile, for example when using the AMI (Achievement Motivation Inventory) to study the correlation among "motivation to success" and "orientation to change". […] I can confirm that Hogrefe is helping us through valid and reliable assessment tools, letting us improve the quality of our output.'
