The limitations of existing browsers and protocols in the administration of tests presents a difficult challenge for WBT efforts. In a different environment measures would need to be taken to authenticate the identity of the test taker. To accommodate this limitation of the Web and to address the high cost of distribution a hybrid approach is emerging which combines the strengths of both mediums. The Web is used to store time sensitive information and the CD-ROM is used to provide access to the sparkle of multimedia training. The courseware on the CD has built-in Internet access and calls upon the centralized server for necessary information.
Organizations can update time-sensitive information once on the central server.
Industry analysts expect this to be a popular alternative to full Web-based training until bandwidth constraints have been resolved.
