WBS finds students in a variety of ways. Historically, students have responded well to inexpensive advertisements placed in newspapers around the world. However, print advertising has become less cost-effective as costs have risen and societies have more and more media vying for people's attention. At the same time, advertising via the Internet is proving to be more and more effective in reaching new students.

WBS is having great success in mobilizing national Christians around the world to reach out to and enroll people to study in the areas where they live. Color handouts and enrollment forms are being used by churches, preachers, follow up workers, and everyday Christians around the world to enroll students. Short term mission campaigns from the States also do a good job of getting the word out about WBS. As noted above, students also proactively provide referral names so that their friends and family can have the same opportunity to study as they have had.

Annually, WBS begins studying with about one million new students. It is estimated that WBS has approximately 2 million students actively taking the courses at any given time.
