You don't need to estimate an IRT model to contribute meaningfully to assessment decisions, but you do need enough psychometric understanding to ask good questions and collaborate effectively. As assessment programs become increasingly interdisciplinary—and increasingly AI-enabled—professionals from product, technology, content, operations, and business functions are expected to engage with psychometric concepts that influence quality, fairness, validity, and candidate experience. This interactive discussion explores what "psychometric fluency" looks like for non-psychometricians, where communication breaks down, and how cross-functional teams can build shared understanding without expecting everyone to become measurement experts.
