In 2017, the overall size of the North American training market was estimated at 161 billion U.S. dollars. While growth has plateaued since 2015, the years from 2009 to 2015 saw significant growth, with the overall market size growing from 110 billion to 160 billion U.S. dollars. Spending on training in the United States is strongly skewed in favor of internal resources. In 2017, just over 40 billion was spent on internal training staff, compared to only 7.5 billion on externally provided products and services. Of the areas outsourced, the most common are content creation, learning management system hosting, and instruction and facilitation.
The two most common training methods used in the United States in 2017 were instructor-led classrooms, or a blended approach combining instructor-led classrooms with some form of technology. However, around 28 percent of companies reported that they use online or computer based training methods only, where no instructor is involved. The area which has the highest adoption of online training is compliance training, with almost two thirds of companies reporting that their compliance training is mostly or all online. Conversely, the areas with the lowest adoption are executive development, management and supervisory training, customer service training, and sales training. As of November 2017, only 40 percent of companies in the U.S. expected to increase their spending on online training.
