The impact of inclusion of literacy and numeracy into Australia's Certificate IV in Assessment and Workplace Training was examined in a case study in New South Wales (NSW). Data were collected through the following activities: interviews with key informants from urban and regional NSW; observations of the delivery of units of competency from the certificate by an urban registered training provider at two 3-day workshops and informal interviews with workshop participants; and a phone survey of a small number of registered training organizations in NSW. A major skills gap was perceived between trainers and assessors with the previous qualifications and what is required for the new qualification, especially in the area of awareness of literacy and numeracy. Trainers and assessors requested more support materials but appeared unaware of resources currently available through the Australian National Training Authority or National Assessors and Workplace Trainers Body (NAWTB) Web site. (The bibliography lists 35 references. The following items are appended: the language, literacy, and numeracy skills required of trainers/assessors as specified in the training package's evidence guide; list of organizations represented by key informants; text of the interview with the presenter of "Workplace Assessment"; and list of 24 resources on the NAWTB Web site.)
