# Validity

Validity indicate the individualized authenticity of assessment results obtained. However, when assessment reliability is absent, the results obtained from such an assessment instrument are completely worthless and unusable to either form an opinion or use as reference point for possible probabilities or a likelihood for being present.

Assessment validity - on the one hand - is to determine the applicability of norms and performance standards for a specific individual. On the other, it also ensure that assessment results are a credible or believable reflection of the true nature of the individual assessed. Assessment validity implies (under the auspices of reliability) that an assessment instrument measures the desired performance levels, traits or attributes of an individual and allows for the drawing of appropriate contextual conclusions from the results as generated and calculated by that particular assessment instrument.
