Systematic tests and scales, besides defining the abilities we are to establish and improve, are of very great service in measuring the status and improvement of individuals and of classes, and the effects of various methods of instruction and of study. They are thus helpful to pupils, teachers, supervisors, and scientific investigators; and are being more and more widely used every year. Information concerning the merits of the different tests, the procedure to follow in giving and scoring them, the age and grade standards to be used in interpreting results, and the like, is available in the manuals of Educational Measurement, such as Courtis, _Manual of Instructions for Giving and Scoring the Courtis Standard Tests in the Three R's_ ['14]; Starch, _Educational Measurements_ ['16]; Chapman and Rush, _Scientific Measurement of Classroom Products_ ['17]; Monroe, DeVoss, and Kelly, _Educational Tests and Measurements_ ['17]; Wilson and Hoke, _How to Measure_ ['20]; and McCall, _How to Measure in Education_ ['21].
