Nine scales, two age bands
Scales B to F were for elementary and high school, with seven minutes each. Scales J to M were for high school and adults, with five minutes each. All were sold by the Teachers College Bureau of Publications [1]. Select a scale to read its first and last sentences.
Fill the blank, then meet the key
Eight one-blank sentences from five of the scales, with Trabue's own lists of words that scored 2, 1 or 0 [1]. Trabue said the lists weren't exhaustive. If your word isn't on one, you play the 1919 scorer and judge it against the examples.
From a 5-point scheme to 2-1-0
The preliminary sentences were marked 5 for perfect down to 0. The published scheme keeps only the top: 2 for perfect, 1 for slightly imperfect, 0 for everything else. Trabue checked what that cost. With 40 pupils in each grade, he correlated the sentences' order of difficulty in grade 6A with their order in grade 8B under each scheme [1].
Almost nothing was lost, even when scoring was cut to plain right and wrong. What mattered, he wrote, was that a scheme "shall be used consistently".
A key written in uniform
Marion Rex Trabue (1890–1972) published the scales in 1916 as a Teachers College contribution to education [3]. The separate Key followed because the first edition sold out while he was in the Army [1].

Trabue ran the psychological staff at Camp Taylor during the first Army trial. The preface to his Key was written while he was still in uniform.
Otis's group scale used answers that a clerk could check against a key without deciding anything. Trabue's lists show how much judgment open answers still needed.
The NIT had a sentence-completion test of its own. It was built for fast group scoring, the same problem Trabue's key tackled.
Thorndike, Trabue's colleague at Teachers College, made Completion one of his four item types. It sits beside Arithmetic, Vocabulary and Directions.
Graded scales for school subjects became whole achievement batteries in the 1920s. Trabue's were among the language scales that came before.
