RESTON, VA (May 17, 2007) Learning Tree International (NASDAQ NM: LTRE) has announced a new entry to its list of courses utilizing RealityPlus, a training methodology in which attendees learn by being immersed in media-rich business simulations. During the 3-day course, entitled Developing Effective Software Estimation Techniques, an expert instructor/facilitator leads activities designed to provide participants with first-hand experience in the many facets of estimating software projects effectively.

• Apply historical data for greater precision in an estimate
