Research says that individuals only retain about 10% of what they are taught in-classroom training. In fact, it's estimated that half of classroom learning is lost within the first 24 hours. While this type of instruction is still required as part of the professional development process, one-off classroom instruction is inadequate to build the knowledge and skills that lead to new behaviors. This is especially true when learning new subjects, such as lawyers who are learning new business development skills.

To build new skills and behaviors, learners need to have the learning reinforced continuously and in multiple ways. You can do this using quizzes and exercises, one-on-one coaching, group coaching, and on-the-job practice (where skills are applied in real-world settings). These 'follow-on reinforcement strategies' can improve skills development and knowledge retention by as much as 90%.
