In the context of the Kirkpatrick Model, 'Reaction' refers to the immediate response of participants to the training. This level assesses how well participants received the training and their feelings about it right after the session. It encompasses aspects such as their attitudes toward the training material, the trainer, and the training environment. Gathering feedback at this stage is crucial as it helps educators understand participants' satisfaction levels and whether the training met their expectations.

The other levels of the Kirkpatrick Model go beyond initial reactions. They focus on learning, which deals with the knowledge or skills gained; behavior, which measures the transfer of that learning to the workplace; and results, evaluating the overall impact of training on organizational performance. Therefore, 'Reaction' specifically captures the initial impressions rather than the deeper levels of knowledge retention or the ultimate effects of training.
