Excerpt from The Distribution and Relations of Educational Abilities: Report by the Education Officer Submitting Three Preliminary Memoranda

Standard I. Is taken as covering a range from St. 10. To St with a mid-value at St. Just as age 7 is used to mean over 70 years and under 80 years, with a mid-value at years. The need for this. Is clear. It is often necessary to discriminate finer shades of ability than the crude class intervals. Teachers for example, will give such assessments as a good St II. Or St. I. Plus, or Grade iii. B and again St. I. For arithmetic has to be averaged with St. II. For reading. In these cases, the original values can be converted into quantitative form, and manipulated algebraically, only by means of a continuous fractional scale. Such a scale then, is eminently suitable for theoretical and statistical purposes. At the same time, the unit of measurement remains closely related to practical experience and possesses a familiar, concrete significance which a novel scale,. Devised ad hoc, would no longer convey.
