Abstract: The present invention provides a system by which customized quality computer-based training (“CBT”) can be presented over a global network such as the Internet with low development costs, low hosting costs, inexpensive class production, and high-quality audio-visual content. A student, having an active connection to the server from a remote client, enters the CBT website and registers as a new student by providing necessary pertinent information to the server host. Upon completion of the registration process, the student begins his or her interaction with the online computer-based training plan. The online plan includes digital images and digital audio that is compressed and transmitted from a host server to the student's computer via the Internet. The images and audio are taken from digital nondigital sources and converted to a digital format. The images for a plan are selected and compressed into an appropriate compression format.
