Custom Psychometric Test
Development & Validation
From concept to validated instrument: we design scientifically rigorous assessments tailored to your specific organizational needs and target populations.
Custom item pools undergo EFA, CFA, Item Response Theory (IRT), and measurement invariance testing.
Our Custom Psychometric Assessment Development Process
Adhering to best practices in psychometric test development proposed by Van Zyl & Ten Klooster (2022), we employ a rigorous, multi-phased methodology to design robust assessment measures.
Operationalising The Diagnostic Framework & Conceptual Measurement Model
The purpose is to develop a bespoke measurement model centered around the unique states, traits, and behaviours you would like to assess. Here, we identify both what inputs to measure and how to link them to core business outcomes and stakeholder perceptions.
Your Organization is Unique
Our team develops custom conceptual models, like the Organizational Health Persona Model, to target your exact needs. Whether it's enhancing employee experience, customer engagement, or organizational culture, we bring science and strategy together for actionable results.
Developing a Predictive Process Model
Identify drivers (i.e. antecedents) of the target factor and map how they affect business and people outcomes. This visualizes the interplay of wellbeing, organizational health, job demands, resources, and performance (including customer, employee, organizational, and supplier antecedents).
Psychometric Evaluation and Validation
Our validation protocols not only meet but exceed professional standards (APA, SIOP, ITC) to ensure your assessment delivers reliable, meaningful results.
Construct Validity
Confirmatory factor analysis, convergent/discriminant validity testing, and multi-trait multi-method approaches to verify we're measuring intended constructs.
Criterion Validity
Rigorous testing against relevant outcome measures to demonstrate predictive power for your specific organizational use cases.
Cross-Cultural Validation
Measurement invariance testing across demographic and regional groups to ensure fairness and comparable score interpretation.
Typical Validation Metrics & Benchmarks
