Whereas psychology seeks to understand the mind, psychometrics is the science of actually measuring mental capacities and processes. It is about taking psychological science—like theories of personality and cognitive ability—and building tools that allow us to measure these underlying traits and abilities of people. Psychometrics are immensely challenging to get right. Unlike other fields where you can directly measure stuff—like height and weight— psychological structures are invisible and therefore can’t be measured directly. Psychometrics is about building tools that indirectly but accurately measure people’s psychological make-up.

Our psychometricians build, refine and test tools like the behavioral assessment and cognitive assessment. That means they are valid and measure what they are supposed to measure. It also means they are precise and reliable. In order to demonstrate validity and reliability, psychometricians gather evidence and conduct analyses using fancy tools, like SPSS and R, and statistical techniques such as Confirmatory Factor Analysis, Latent Modeling, and Item Response Theory.

You should know that both the behavioral assessment and cognitive assessment are psychometrically rigorously developed tools and we have the technical documentation to back it up.
