Training for employees can take many forms. Whether training is in-house, in the field or online training, one thing is certain, training takes time. Participating in training can take time away from the office or job-site production. If training is in-house, the trainer and trainee have time invested. Many formal training workshops incorporate an assessment of participant skills at the close of training. Ensuring the key concepts addressed during the training are retained by a training participant weeks to months after training is key to defining the effectiveness of the training. However, post training content retention is often not formally assessed or tracked During this training we will review types of retention activities and how the results of the activities can help identify deficiencies in training or areas for further staff development.
