Background
About Crystal Clack
I'm a registered Psychometrist specialising in psychometric research, data analysis, and the practical application of psychological assessments. My expertise is grounded in both classical test theory and modern methods such as Rasch modeling, with a strong focus on developing assessments that are valid, reliable, and fair. I’ve worked on applied research projects, updated normative data, and developed technical documentation to support assessment certification. I also enjoy knowledge sharing and have lectured on psychometrics and research methods. My professional interests lie in test development and the ongoing refinement of psychological tools. I’m passionate about ethical, evidence-based assessment and continuous improvement in measurement practices. I’m currently seeking new opportunities where I can contribute to meaningful work in psychometrics, assessment, or research. I’m especially interested in roles involving test development, validation, applied research or lecturing. I welcome connections and conversations with professionals in related fields.
