White Paper Now Available, Conversion:  The Benefits and Best Practices of Computer-based Testing

BALTIMORE, MD. SEPTEMBER 7, 2004 - Thomson Prometric, the global leader in technology-enabled testing and assessment services and part of The Thomson Corporation (NYSE: TOC; TSX: TOC), today introduced the online version of its white paper, Conversion:  The Benefits and Best Practices of Computer-based Testing.  Organizations still using traditional paper and pencil-based exams are using this guide to further understand the importance, process and benefits of converting to computer-based exams.

Monthly, nearly a million computer-based exams are delivered in highly secure, technology-enabled testing centers globally.  This knowledge testing is strengthening markets such as academic, government, IT, corporate and pre-employment, and includes well-known exams such as the Graduate Record Examination, Microsoft Certified Systems Engineer and Korean Language Proficiency Test exams.

"Converting from a paper and pencil-based exam to today's computer-based format is a simpler and less expensive process than most people realize," said David Meissner, Thomson Prometric executive director of Testing System Strategy.   "Computer-based testing is much more secure then its paper-based predecessor and provides a consistent, reliable and unbiased method for confirming knowledge."

Other computer-based testing benefits include comfortable and convenient test environments, multimedia question types and reference materials, immediate score reporting, and 24x7 exam scheduling options. 

Conversion:  The Benefits and Best Practices of Computer-based Testing also includes FAQs for both test sponsors and test takers, and recommendations for promoting a computerized testing program in the marketplace.

The conversion guide is available in the Thomson Prometric Knowledge Center, http://www.prometric.com/PressRoom/KnowledgeCenter/default.htm
