Researchers examined the management and conduct of assessments at the diploma and advanced diploma levels within training packages across Australia. The principal data collection activities were as follows: (1) a literature review; (2) examination of seven training packages; (3) a survey completed by 28 registered training organizations and 33 assessors; and (4) focus groups and interviews with selected stakeholders, including industry training advisory body representatives, an assessor network, and a reference group of industry practitioners. The following were among the issues identified by the research: (1) the assessors perceived considerable ambiguity in the competency standards within training packages; (2) most assessors identified a need for more assessor skills and experience and more time and resources to complete quality assessments; and (3) an estimated 65% of training providers registered for the higher-level qualifications in the training packages reviewed do not deliver training or assessment services for those qualifications. The study also established that assessors working at the diploma and advanced diploma levels need skills in two broad areas--the skills to develop a holistic or integrated assessment approach and knowledge of learning and assessment theory. Nine areas for further research were also identified. (Twenty-two tables are included. The bibliography lists 37 references. The survey questionnaire is appended.) (MN)
