Final answer:
A good performance standard for evaluating a trainee's ability is 'Measurable and Objective' to ensure fair and clear assessment. This provides reliable and valid measures that are free from personal bias, making them consistent and reproducible for the accurate evaluation of performance.
Step-by-step explanation:
When evaluating a trainee's ability to perform a task, the terms that make a good performance standard are Measurable and Objective. These criteria ensure that performance can be quantified and assessed without personal bias or opinion influencing the outcome. Vague, subjective, arbitrary, and inconsistent standards do not provide a clear, fair, or reproducible way to gauge a trainee's performance.
For example, considering target shooting accuracy to illustrate the concept:
- a. A precise but inaccurate set of measurements means the shots are close together (precise) but not hitting the target (inaccurate).
- b. A set of measurements that is both precise and accurate means the shots are both close together and hitting the intended target.
- c. A set of measurements that is neither precise nor accurate means the shots are scattered and not hitting the target
This aligns with the principles of reliability and validity in measurements, which are also important for evaluating performance standards.
Furthermore, the subjectivity of certain questions or statements, such as human rights issues, opens the discussion to debate and lacks the concrete measurability needed for objective evaluation. Therefore, performance standards must be designed with objectivity and quantification in mind to be effective.
