Testing 200,000 men a month without leaks
From April 1918, Army examiners were testing more than 200,000 men a month in groups of up to a few hundred. If every room used one booklet, answers would travel through a camp within days. The Alpha was printed in five forms, numbered 5 to 9. Each kept the same structure and difficulty but had different items, so forms could be rotated between rooms and sittings.
All five used the same examiner's procedure and time limits. Their scores were converted to the same A–E letter grades, so a recruit's grade didn't depend on which form he happened to get.
“This is a test of common sense”
All sixteen questions of the chosen form, in the original order and wording. Switching form clears your answers. Pick the best of three answers. The recruits had 1½ minutes; the timer below runs the same, and you can finish untimed afterwards.
Eight tests, same as every form
As with Form 6, Tests 2 and 4–8 of these forms are printed sideways in the 1920 book, and the scanned text is unreadable. They aren't transcribed here rather than guessed. Test 1's oral directions were also written separately for each form; Form 6's are on its own page.
