In developing countries, for the most part, traditional methods of selecting students for secondary schools, technical and vocational institutions, teacher training colleges, and universities are unable to ensure that the most capable applicants receive the limited opportunities available. To remedy this situation, the author has assembled and incorporated into this handbook a collection of testing procedures which he has found useful in large-scale testing programs in developing countries. In his discussion, the term "large scale" describes examinations taken by at least a thousand candidates on a single schedule date. Nevertheless, most of the chapters are applicable to examinations given on a smaller scale. The handbook may also be valuable to school headmasters and teachers who are interested in the workings of a testing organization, a body that often exerts great influence on their lives and those of their pupils. The handbook is divided into these sections: (1) Publicity, (2) Registration, (3) Item Preparation, (4) Pretesting, (5) Editing, (6) Reproduction, (7) Distribution/Administration, (8) Scoring/Processing/Reporting, (9) Overall Security, and (10) Costs.
