This book attempts to present the more common areas of measurement and evaluation in such a manner that the professional student, with the help of reference books and other selected readings, will understand the value of measurement and evaluation by personally thinking and acting on problematical situations. An effort has been made to afford the student a chance to think about and work with tests with a view toward their practical application. In general it is the aim of the book (1) to assist the future teacher in understanding the place and importance of measurement in the teaching process; (2) to provide a way for students to examine more closely some of the tools and other elements of measurement and evaluation, so they may become equipped to evaluate scientifically the school program in terms of educational aims and objectives; (3) to embrace in a practical manner the fundamentals of appraisal and to relate these to curriculum content, method of instruction, and pupil advancement; (4) to provide the student with sufficient understanding to realize that the more valid the measurement and the more judicious the evaluation of results, the sooner the goal may be attained; and (5) to show how measurement may be used for the determination of pupil status, the classification of students, individual analysis and guidance, appraisal of teacher and program efficiency, and gaining the support of the administration and the community. A definite plan of construction was followed in building this text. It was intended that the work should develop logically from the first to last chapters; that is from the more fundamental considerations to the more detailed ones.
