With each passing year, there seems to be increasing pressure for elementary, middle and high school students to make good grades and prepare for a path to higher education. For some kids, this means getting help from a tutor to bridge any gaps in understanding in certain subjects. Since more families often have reliable high-speed Internet connections at home, too, Internet-based tutoring services are growing. 

When you apply for these jobs, you usually have to take tests in your selected subject areas and submit to background checks. Though you could start your own online tutoring service, sites like Tutor.com have already done the legwork for you in terms of marketing. These sites match thousands of kids with tutors each week. While many Internet-based jobs offer flexible hours or multiple shifts, tutoring services might require you to be online during a specific block of time or reward you for doing so. 

This encourages tutors to be available during the heaviest demand. For example, when Tutor.com has more tutors than tutoring requests, it places tutors on a waitlist and gives preference to tutors who work at least five of hours per week in the 4 p.m. to 11 p.m. EST time slot Sunday through Thursday.
