An assessment instrument is a standardized tool or procedure used in psychology to measure, evaluate, or observe specific cognitive, emotional, behavioral, or developmental aspects of an individual. These instruments are designed to provide valid and reliable information for diagnosis, intervention, or educational planning.

Every psychological assessment instrument should meet the following features:

1. Validity – the instrument measures what it is intended to measure.

2. Reliability – it produces consistent results over time and across contexts.

3. Standardization – it follows the same procedure for all individuals.

4. Relevance – it is appropriate for the construct or population being assessed.

5. Sensitivity – it detects developmental differences or changes.
