Threats to validity in training evaluation refer to factors that may impact the accuracy and reliability of the evaluation results. These threats can include issues like selection bias, instrumentation error, or participant motivation, which can distort the findings and affect the credibility of the evaluation process. Understanding and mitigating these threats is crucial for ensuring that the training evaluation accurately reflects the effectiveness of the training program.
The characteristics of evaluation are: validity and reliability
The main threats to validity are bias, confounding and chance. But keep in mind the internal and the external validity. Internal validity is the extent to which systematic error is minimised during the stages of data collection. where as the external validity encompasses the extent to which the results of the trials provide a correct basis for generalisation.
By ruling out a series of threats to that validity. Please see the link for a list of them.
"A threat to external validity is an explanation of how you might be wrong in making a generalization."[4] Generally, generalizability is limited when the cause (i.e. the independent variable) depends on other factors; therefore, all threats to external validity interact with the independent variable.
Some examples of threats to validity that could impact the results of this study include selection bias, measurement error, confounding variables, and researcher bias.

When training is given on the job, such as in training servers in restaurants, no evaluation is usually given. Employees are simply given a section to handle after the training is complete. The reasons for no formal evaluation can vary from one business to another, but it is possible that most have either not considered the benefits of evaluating the training or simply do not believe formal evaluation is necessary.
The Evaluation phase of the Systems Approach to Training (SAT) process is used continuously throughout the training lifecycle. It involves both formative evaluation, which occurs during the training development and implementation stages to gather feedback and make adjustments, and summative evaluation, conducted after training to assess its effectiveness and impact. Continuous evaluation ensures that training remains relevant and effective in meeting learners' needs and organizational goals.

There are a number of ways to reduce threats to validity:By arguing against the threatBy observing and measuring the threat.By analysisBy preventive actionBy design.
The principles of evaluation in the context of physical activity include relevance, reliability, validity, and practicality. Relevance ensures that the evaluation measures pertinent aspects of physical activity, while reliability refers to the consistency of the results over time or across different evaluators. Validity assesses whether the evaluation accurately reflects the intended outcomes or goals of the physical activity program. Lastly, practicality considers the feasibility of the evaluation process in terms of time, resources, and accessibility.
