Prolydian helps test publishers and administrators use technology to improve the testing experience from design to delivery. "Why Prolydian?" you may ask. The name is derived from a type of mineral known as the "Lydian stone." Its discovery in ancient times provided the basis for a method of determining the quality and purity of precious metals and stones. Also known as a "touchstone," the Lydian stone would be scratched with a known-good sample of gold, for example. Then, when a sample of unknown quality was presented, a scratch could be made next to the original and compared. Similar appearance would indicate similar quality. It struck us in our research of the Lydian stone technique that it is something of a metaphor for the practice of exam development and administration. Known good answers are compared to an examinee's attempt. Similar answers indicate a similar level of excellence. Is your exam candidate's "scratch" on the stone similar enough to the known good "scratch" to indicate a similar excellence in quality? We could think of no better symbol for assessing the qualities of candidates than this certification software. In that same vein, our tagline was revised to indicate a broader focus, as well. "Lead them to excellence" is a promise to our clients of new and expanded tools for helping their chosen profession or organization to reach new levels of achievement, as well as a reminder to us of our own mission. Our new corporate vision embraces the full range of services needed by anyone whose business involves fostering learning and achievement -- be it professional, education, or otherwise.
