This book documents the results of a survey to acquire information regarding the English proficiency of second generation minority group children in Britain. The aim of the survey was to do the following: to establish the level of proficiency in English of minority group pupils of junior school age who had received different educational treatments, to compare the proficiency in English of British born minority group children with that of similar born to indigeneous parents, to compare the proficiency in English of both groups of children born in England with that of those born abroad of similar age and socioeconomic background, and to relate different levels of proficiency in English to characteristic features of the pupils' background and learning history. Consideration was given to the aspects of the children's home and school background in relation to their performance in English. The chapters of the book focus on: the tests (outline of the tests, development of the tests, findings arising out of test development, and interpretation) design of the survey (proposed sample and variables), administration of the survey, nature of the sample tested, treatment of the data from test, performance in relation to the main variables (age, sex, ethnic group) and performance in relation to the background variables (percentage of immigrants in school, background education, length of stay in Britain, special English teaching, preschool education, English spoken at home, and English spoken at school).
