Whether it is for staff in an afterschool program or another field, quality training should always consist of three elements, which Toolbox Training refers to as the 3 P's.
Principle: This is the basic information provided in the workshop. It should be new knowledge to participants or a twist on familiar information. Sadly, many trainings never move beyond this phase.
Practice: For a training to truly be training, participants must get a chance to apply the new information they've learned in the training setting. If this doesn't happen in the training, the likelihood that participants retain the information drops significantly.
Plan: Finally, a quality training charges participants with developing a specific plan of action for how they will use what they've learned beyond the workshop. Without any next steps, participants are unlikely to follow-up the workshop in any meaningful way.
