The specific value will vary depending on the form of the tool and the target of the assessment.

How to prevent human interference to reduce the assessment error, roughly divided into two cases, one is the use of standardized assessment tools (such as psychometric tests, objective exams) in the assessment tool under the premise of effective assessment errors often come from the operation of the link, such as not according to the process of operation, the test site environment is not up to standard, the manual scoring of the assessment in the scoring process will also produce errors. Another situation is the assessment by the assessor (examiner) directly scoring assessment methods, such as interviews, no-lead group discussions, role-playing, job simulation and other evaluation center methods, the error mainly comes from the topic (scenario) design and the assessor (examiner) of the degree of specialization.
