Query: Drummond's textbook

Students whose field of studies will take them into research and/or testing procedures should consider this book. It covers the historical and philosophical foundationsof testing, the ethical issues involved, and goes into great detail on all the statistical aspects of appraisal. Parts of it are over my head but this is due to my poor math background rather than the author's style and content.
