Here's a quiz: Three days after a training session, how much of the information will a typical attendee have retained?
Take a guess.
50 percent? Lower.
30 percent? Still too high.
The answer is 10 percent.
Amazing, isn't it? Even with skilled trainers presenting relevant information to receptive, intelligent people, retention is likely to be disappointing. On top of that, even fewer people actually change their behavior as a result of what they learn.
