Service Level Chicanery

For online tutoring, students want on-demand help. Frankly, why else would they choose to be tutored online? As the online tutoring industry evolves into a larger market, it is interesting to note the lengths to which companies will go to to promise on-demand assistance. For instance, Tutor.com claims on-demand tutoring on its web site and in various corporate blogs. However, their service is only available from 11 AM - 10 PM (PT). Perhaps a more accurate claim would be "on-demand tutoring except for 13 hours per day." Worse, TutorVista (and many other small tutoring companies) claim 24/7 tutoring. In practice, this means that a student can schedule a tutor at any time for any time with sufficient notice. It does not mean that a student can get help exactly when they want it. At SMARTHINKING, we offer true on-demand math tutoring for the fall and spring semesters. During the summer, drop-in tutoring is available for 16 hours per day because there is not a sufficient volume of students to support full 24/7 access.

Why would companies spin these little white marketing lies? Because true on-demand tutoring -- 24/7, drop-in, live service -- is more expensive, requires greater scale, requires greater expertise, and requires greater data than pre-scheduled tutoring. These companies are trying to attract customers without investing in the tutoring force and management expertise necessary to offer on-demand service.

To understand why on-demand tutoring is more expensive and more complex, it helps to think of on-demand tutoring like a customer service center. When you call a company or utility, you expect to talk to someone on the other end. Running such a center is very similar to running an on-demand tutoring service. A critical operational variable in a call-center is "utilization capacity." This is the percentage of time that tutors spend tutoring students. It utilization capacity is too high then students have to wait a long time for tutors. If utilization capacity is too low, then the company is losing money. For instance, if a tutor is being paid $12 per hour and utilization capacity is 50%, the cost per hour tutored is $24. But, because one or more tutors are almost always available, there are no wait times. So, utilization capacity and wait times are inter-related variables. To do it right, a company needs to set a service level target and then determine the target utilization capacity to meet that target.

So, utilization capacity and service levels are mutually dependent variables. However, achieving a target service level also depends on the average length of a tutoring session. For instance, if a typical session in a call center is 2 minutes long, then a customer service center doesn't need to staff as many people to achieve a low wait time because customer service representatives are frequently available. However, for online tutoring, the average session length is around 30 minutes. This means that, with a small number of students per hour, an online tutoring company must have a very low utilization capacity to meet minimum desired service levels. As the number of students per hour rises, utilization capacity can rise while keeping service levels constant. Because utilization capacity can rise, it costs less to offer on-demand tutoring with a large number of students than with a small number of students.

Lastly, to manage all of this efficiently, an online tutoring company needs management sufficiently skilled to schedule tutors appropriately and sufficient data to know when the peaks and valleys of demand are likely to be.

So, to sum up, true on-demand tutoring generates higher labor costs because a portion of a tutor's time will not be used, requires scale to keep the unused portion of time as small as possible, requires management expertise, and good data systems. This is a significant investment that all small online tutoring companies are unwilling to make. The expense of true on-demand tutoring combined with its attraction to customers is the impetus behind the false advertising cropping up in the online tutoring industry.
