Army Alpha Forms 7, 8, 9: Parallel forms 7, 8, 9 of Army Alpha

Forms 7, 8, and 9 of the 1918 Army Alpha - the remaining three parallel forms used during WWI testing. Same 8-subtest structure as Forms 5 and 6 with different specific items at each difficulty level. Used to prevent answer-sharing between adjacent testing groups.

About the Army Alpha Forms 7, 8, 9

Forms 7, 8, and 9 round out the five parallel forms of the Army Alpha. Form 5 we built as a full interactive version; Form 6 has its own page; Forms 7, 8, 9 are grouped here for completeness.

All five Alpha forms share an identical structure: 8 subtests, the same time limits per subtest, the same scoring conventions. Individual items differ across forms to prevent inter-group answer-sharing, but the difficulty distribution is calibrated to be equivalent. Population norms apply across all five forms uniformly.

The actual items for Forms 7, 8, and 9 appear in the Yoakum/Yerkes 1920 volume on pages 222-244, with the keys on pages 70-77. We have not built separate interactive versions for these forms - they would essentially replicate the Form 5 interactive with different specific items.

About this interactive version: Forms 7, 8, 9 are described here rather than implemented as separate interactive tests. To experience the Army Alpha interactively, take Form 5 at /en/historical-iq-tests/army-alpha. For the actual Forms 7, 8, 9 items, see the Yoakum/Yerkes 1920 PDF.
