Business certification and industry schools

2013 revenue: $2.78 billion

2018 revenue: $2.08 billion

"This industry faces rising competition from junior colleges, trade schools and universities. Demand for industry schools has declined because more students are choosing degree programs to boost their chances in an increasingly competitive job market. Additionally, declining demand has caused operators to lower prices for courses, which has eaten into industry profit margins."

The risk level for this industry is 'high' and revenue is expected to fall at an average annual rate of 5.6% over the next five years. But there is opportunity for schools with online classes.
