A variety of new approaches have been developed in recent years for evaluating training and occupational modeling, particularly in terms of occupational specifications and training requirements. Several of these innovative approaches have now been validated and are available for operational use. Others are still in the process of development or validation. Many of these new approaches make use of computer-assisted advanced data collection technologies, and are part of the general process of upgrading occupational and training evaluation data bases. Several of these studies are part of a broader technology development R&D effort aimed at enhancing and expediting collection of occupational-specific data needed for improved decision making and revision of operational military manpower, personnel, and training systems.
