The 5-14 Development Programme was a major reform encompassing the whole of the curriculum, assessment, national testing and reporting for pupils of age 5 to 14 in Scotland. Between 1989 and 1993, national guidelines were developed for five curricular areas: English language, mathematics, environmental studies, expressive arts, and religious/moral education; and for personal and social development, reporting, assessment, and national testing. This Executive Summary of the first four years' evaluation sets out the main findings against the background to the development program itself and to the evaluation. It is in three main parts. The first part begins by placing 5-14 in the context of curriculum changes in Scottish schools since the 1960s. The second part describes the structure and methods of the evaluation program, which comprised four coordinated projects. The third section summarizes the findings, drawing upon the findings described in detail in the final reports. It concludes by bringing the findings together to consider the implementation in relation to the overarching aims of 5-14: to promote breadth, balance, coherence, continuity, and progression in pupils' learning.
