Why is it important to provide training for assessors?

Providing training for assessors is vital to ensure consistency and validity in scoring. When assessors are trained, they develop a clear understanding of the assessment standards, criteria, and procedures, which helps maintain uniformity in the evaluation process across different assessors and instances. This consistency is essential in standards-based assessment, where the reliability of scores directly impacts the credibility of the assessment results. Validity is equally important; trained assessors are more likely to accurately measure what the assessment is intended to measure, supporting fair and equitable evaluations for all students. This systematic approach to assessor training ultimately leads to enhanced educational outcomes as it fosters a standardized interpretation of assessment criteria, thereby upholding the integrity of the assessment system.
