About
I'm Gregory Gorman, a psychometrician and lecturer in psychology in London. My PhD is in psychometrics: the science of measuring things that cannot be observed directly, such as skills, attitudes and wellbeing, and of knowing how far the resulting numbers can be trusted.
I consult on two kinds of problem: organisations that run programmes and need credible evidence of what they achieve, and organisations that sell or use assessments and need to know the scores mean what they claim.
Background
Research and teaching
Scale development and validation, item response theory, structural equation modelling and measurement invariance, alongside mixed-methods evaluation of applied programmes. My doctoral work was the independent design and validation of a new measure, from construct definition to publication, and I have co-authored a review of whether knowledge-translation frameworks hold up inside a national health service. I teach research methods and statistics at university level.
Applied work
Health workforce policy: analysis of nurse staffing and skill-mix data, alongside systematic reviews of staffing models, for the Safe Nurse Staffing and Skill-Mix extension to Irish emergency departments. Public-health research on intervention fidelity and air-quality risk. Published work assessing whether an existing performance metric measured what it claimed. Theory of Change facilitation with the Open Innovation Team, working with senior Department for Education stakeholders.
How I work
Fixed scope, fixed fee
You know what you will receive and what it costs before work begins.
I do the work
The person on the scoping call runs the analysis and writes the report.
Repeatable where it should be
Where measurement must be repeated, I build the tooling: automated scoring, reporting pipelines and reproducible R scripts your team can run without me.
Tools
Analysis in R, which is my working language for psychometrics and modelling. I take data in whatever form you hold it, including SQL databases and survey platform exports.
