What type of assessment can trainers use to evaluate a learner's abilities throughout the training?

The type of assessment that is most effective for evaluating a learner's abilities throughout training is informal assessment. This method typically involves observations, discussions, and check-ins that allow trainers to gauge a learner's understanding and skills in a more flexible and ongoing manner. It focuses on real-time feedback, enabling trainers to adjust their methods or provide additional support as needed. Informal assessments help to create a more dynamic learning environment, making it easier for instructors to identify areas of strength and areas that may need improvement.

In contrast, formal assessments are typically structured and often used at the end of a training program to evaluate overall learner performance. Summative assessments, a subset of formal assessments, are specifically designed to measure the outcomes of the training once it is complete. Standardized assessments are pre-designed and consistent in measurement but may not provide the same level of adaptability as informal assessments in a training context.
