The themes of this volume are equality and inequality in education. Given the doubling of students in higher education and the questioning directed to the traditional role, and the nature of higher educational institutions, this conference was designed to focus on education at all levels and on the preparation for the professions and public service. The contents are: biological inequality and education; the psychology of primary education; the practice of education at the primary stage; making adults more equal; the scope and limitations of public educational policy; the internal structure and organization of comprehensive education examiniations in education; the Galton lecture 1974: the docimological dilemma of quality control and quantity surveying; international differences in higher education; student participation and higher education; aims of today in the education of the lawyer; the education of the professional and of the manager; and unsolved problems in medical education. Issues debated in previous symposia covering various sociobiological aspects of contemporary problems are noted to remain unresolved, and beliefs held earlier concerning the potential of education as a tool of social engineering are stated to be regarded by some as native and contradicted by research evidence.
