The study investigates the nature and extent of provision of English as a Second Language (ESL) programs and services for students of non-English speaking background (NESB) in government school systems in the six Australian states and two territories and the interrelationship of state/territorial education authority provision and levels of commonwealth funding. The study further examines perceptions of state/territorial service providers of where the onus of responsibility for ESL provision lies. The study is limited to examination of ESL provision at the school level in government education systems only and does not address services for adult NESB learners or provision in the non-government sector. The study is set in the context of the impact of commonwealth immigration policies on the nature of Australia's multicultural society and on the evolution of provision of appropriate programs and services for NESB students in Australian government schools. The major findings to emerge from this study which bear on the issues identified in the literature and which are of significance for the future of ESL service delivery are: · the existence of overall commonality of definition of NESB students and identification of such students for ESL programs on the basis of need, but a degree of variation in procedures used by state and territorial systems which falls short of standard practice and renders comparative measurement of perceived shortfalls in provision difficult; · variation in definition of intensive programs which renders comparison of provision difficult; · strong commonality in overall provision of both programs and services across all schooling sectors, with limited local variation in service delivery; an increasing commitment in all systems to the mainstreaming of ESL provision through language across the curriculum programs aimed at complementing specialist ESL provision by enabling mainstream teachers to accept responsibility for the language needs of NESB learners; · variation in degrees of dependence on commonwealth funding for provision of programs and services ranging from almost total dependence on commonwealth funding in two systems to significant local education authority provision in four systems; · commonality of opinion among local service providers of the commonwealth's responsibility for some degree of funding of ESL provision, but variations in perceptions of the extent of the commonwealth's responsibility in this area; · commonality of experience of initial identification of need at the local level, but dependence on commonwealth intervention to approach adequate provision to meet identified need; · a degree of tension between on the one hand, recognition of individual differences among systems and the concomitant need, or desire, for state/territorial autonomy in service delivery; and on the other hand, recognition of commonality of purpose and provision and the concomitant need for some standardisation of practice in the interests of efficiency and accountability of service delivery. The study concludes with an examination of the implications of these findings for policy for future ESL service delivery.
