After these measurements have been secured, refer to the table for classifica- tion. For example, a boy’s age is 14 years and 10 months, his height 6114 inches, and his weight 136 pounds. The exponent for 14 years and 10 months is 30; the exponent for 6114 inches is 29, and the exponent for 136 pounds is 22. The sum of these ex- ponents (30, 29, 22) total 81. We find from the table that the boy is in Class C, and is expected to meet the standards listed for his class on fol- lowing page. The sample individual record chart on page 22 provides for three separate testings during the school year. A com- parison of the records will indicate the progress being made. The exponents for age, height, and weight may be found by consulting the Classification Scales. These are added and the Class recorded. The column headed “Score” refers to achievement or T scores, a system of evaluating different types of tests on the same basis. Where these scales are not available, the “Score” column may be omitted. Column “‘r’ refers to rating: Fair, Good, and Excellent, as found in the chart on Standards. Exp. Age Height | Weight || Exp.
