The educational services market is large and growing with several types of opportunities available. As of 2008, there were approximately 58,113 establishments in the industry, which earned a combined $19.4 billion dollars in revenue. The industry is largely fragmented – the fifty largest companies represent just 30% of the total revenue in the industry. In 2006, there were 55.1 million students attending school in grades K-12, all of who are potential clients for educational services - and that number is expected to increase to 74 million by 2015. However, an education franchise isn't just limited to tutoring young people in traditional school subjects like math and science - education franchises extend from traditional school subjects like math and science, to child care and early education programs, to classes for all ages in career education, art, dance or even driving. Overall, however, the field is expanding – educational services in the United States are forecast to grow by 5% per year over the next five years. The growth is largely attributed to the growing global competitive landscape and the emphasis on higher education in the U.S. as more and more blue-collar work is being shipped overseas.
