What three psychometric criteria are most important for assessments in schools?

The three psychometric criteria that are most important for assessments in schools are reliability, validity, and efficiency.

Reliability refers to the consistency of the assessment results. An assessment is considered reliable if it produces stable and consistent scores over repeated administrations or across different contexts. This ensures that students' scores are dependable indicators of their abilities or knowledge.

Validity is crucial as it determines how well an assessment measures what it claims to measure. If an assessment is valid, it accurately reflects the students’ knowledge or skills related to the specific content or standards it is intended to evaluate.

Efficiency pertains to how effectively an assessment can be administered and interpreted. An efficient assessment is one that balances the time taken to administer and score it with the quality and depth of the information it provides about a student’s performance.

These three criteria are fundamental in ensuring that assessments yield meaningful, actionable data that educators can use to inform instruction and support student learning.
