The ability of laboratory testing personnel greatly affects the accuracy of test results, and the ability of personnel is not fixed from graduation. Laboratory testing personnel need to constantly learn and make progress to adapt to the needs of laboratory development, and the verification of personnel capabilities is particularly important.
As laboratory testers, we need to understand the basic methods for verifying personnel's abilities in order to develop our career plans along the right path. Throughout the past, the verification of personnel's abilities can be summarized into the following methods.
Exam assessment

Exam assessment is the most direct and simple method, which is to organize personnel to give a collective lecture. The learning content is presented in the form of charts, text, etc. on the lecture notes, and then employees are allowed to listen. Then, the content and key points of the lecture are presented in the form of test questions for everyone to answer. The knowledge content mastered in this way is clearly displayed on the test questions. The evaluation method is to score based on the standard answers, and the efficiency of the students in listening is intuitively displayed through the number of scores. The disadvantage is that the theoretical aspect is strong, but the practical aspect cannot be reflected, which is called "talking on paper"!
On site questioning

On site questioning is a means of teaching, mainly aimed at employees who are distracted during class, and using questioning to draw their attention back. Naturally, it can also be used as a way to test employees, as the content is highly random and the coverage is incomplete, making it difficult to fully grasp the listening effect of students.

Live demonstration

On site demonstrations are an aspect of assessing employees' practical abilities, mainly reflecting the implementation of standard methods through their actions. The supervisor first requires rich operational experience. Supervision can be a specific operational process or the entire operational stage, but its evaluation is difficult to distinguish and subjective consciousness is relatively strong. It is not easy to form a unified opinion on the evaluation results.

Unification of vision

Having a unified vision can ensure the participation of all employees, but there are limitations to the testing items, which are generally applicable to the final rating process such as color fastness, fuzzing, and pilling.

Blind sample testing

Blind sample testing is a retesting of samples with known results, which determines the ability of personnel by comparing two results. It is mainly applicable to internal quality control, especially for numerical testing projects. It requires evaluation analysts to have a certain knowledge of data analysis and the ability to evaluate and analyze test data.

Laboratory Capability Verification

Participating in laboratory proficiency testing is the most direct and authoritative way, but because its results directly affect the reputation of the laboratory and the cost is high, the laboratory should make sufficient preparations before verifying personnel, especially when new personnel are not suitable for this method.
