"Any time that I can utilize key performance indicators to measure a training program's effectiveness, I do just that. If I'm training warehouse staff on being efficient on the job, I can utilize order fill times prior to and following the training as a measurement of the success of the training. If a training session I create utilizes a quiz or test, looking at the results of those is a way of determining the training's effectiveness, and I can adjust the program if needed. Sometimes, it is necessary to rely on more subjective data like feedback from those attending my training and their managers. Any time I conduct in-person training, I utilize a feedback form that has learners rate the content of the training and my delivery. I have used this feedback consistently over my career to improve."
