This study evaluated whether the addition of a writing section to the SAT Reasoning Test™ (referred to as the SAT® in this study) would impact test‐taker performance because of fatigue caused by increased test length. The study also investigated test‐takers' subjective feelings of fatigue. Ninety‐seven test‐takers were randomly assigned to three groups: the first group took a current SAT with no essay; the second group took a pseudo new SAT composed of the current SAT plus an essay, with the essay appearing in the first section of the test; and the third group also took the pseudo new SAT with an essay, but with the essay in the last section. Test‐taker performance on the verbal and math sections and the essay was then evaluated and compared. The results indicated that while the extended testing time for the new SAT may cause test‐takers to feel fatigued, fatigue did not affect test‐taker performance.
