More than 2. 6 million students in the United States were expected to study online through courses and tutoring fall, up from 1.9 million in 2003. according to an online research group.

Burck Smith, chief executive of Smarthinking, credits the rise in demand for online educational to services to several factors. These include an increase in the number of non-traditional students who don’t have a lot of time to campus resources, a more competitive educational landscape in which colleges and schools are trying harder to students with additional services and students greater familiarity with the Internet.

Terry H. Coye, director of tutorial and instructional programs at Gallaudet University, said his school turned to Smarthinking to increase its limited tutoring services for graduate students. With many of Gallaudte’s deaf and hard of hearing students accustomed to learning online, the service was a good fit, Coye said.

Founded in 1999, Sniarthinking employs more than 450 part-time instructors from around the world to offer round- clock tutoring. Though people might worry that a student could get too much help from someone outside the class-room, the company said it trains its tutors—who get an average of 15 hours of training—to guide students through prob-lems and not give away the answers.

“Long-term, there is no reason to believe online tutoring is no! going to grow as students go online and take classes,” said J. Mark Jackson, director of a market-research firm. Because it is additional service rather than a key offering, he said, it is unclear how large the market might grow.
