This evaluation report presents the details and results of an experimental, compensatory language program designed to improve the standard English language facility of young aboriginal children on the assumption that this would contribute to improvement in reading and other aspects of academic performance. The pilot program was administered during the second half of the children's first year of school. Chapters in the report describe the language competence and school achievement aspects of the testing program, psycholinguistic abilities of aboriginal school entrants, aspects of the oral language development of aboriginal school entrants, changes in psycholinguistic abilities and oral language development of aboriginal children after one year at school, and aspects of school achievement after one year at school. Tables provide statistical details on test results and comparisons between the experimental and control groups. (VM)
