2. The Psychometric Foundations of IQ Testing in the UK
At the core of any credible psychological assessment, including IQ tests, lie two fundamental psychometric properties: reliability and validity.
In the UK, these principles are paramount in the development, selection, and application of cognitive assessments.
Reliability: Consistency in Measurement Reliability refers to the consistency of a measure.
A reliable IQ test should produce similar result IQ scores follow a normal distribution (mean 100, SD 15).
3. Standardisation and Norms: The UK Context

This is achieved through standardisation, a process that establishes norms for a specific population.
In the UK, the development of culturally and demographically appropriate norms is a crucial aspect of responsible IQ testing.
The Importance of UK-Specific Normative Data IQ scores are typically presented as Standardization Norms derived from large representative samples.
