The completion of the first ten years of this journal is an occasion for review and reflection. The main issues that have been addressed over the ten years are summarized in four main sections: Purposes, International Trends, Quality Concerns and Assessment for Learning. Each of these illustrates the underlying significance of the themes of principles, policy and practice , which the journal highlights in its subtitle. The many contributions to these themes that the journal has published illustrate the diversity and complex interactions of the issues. They also illustrate that, across the world, political and public pressures have had the effect of enhancing the dominance of assessment so that the decade has seen a hardening, rather than any resolution, of its many negative effects on society. A closing section looks ahead, arguing that there is a move to rethink more radically the practices and priorities of assessment if it is to respond to human needs rather than to frustrate them.
