Test Scores & The Time of Day

Pacific Standard: “As it turns out, each hour that passes before starting a test drags scores down by a little bit, meaning students who take a test late in the day will perform noticeably worse.” A study by economists Hans Henrik Sievertsen, Francesca Gino, and Marco Piovesan “analyzed scores from every student who took the Danish National Tests between the 2009–10 and the 2012–13 school years … Tests were given in three parts, presented to each student in random order, and lasted throughout the day, with breaks around 10 a.m. and noon.”

“Percentile rankings, which show where students rank on a 100-point scale, declined by about two-tenths of a point per hour on average, though how much scores dropped—and whether they dropped at all—changed throughout the day. Students who took a test at 9 a.m., for example, ranked 1.35 points lower than those who were tested on the same material at 8 a.m. Ranks increased 0.37 points after a 10 a.m. break, but dropped again by 0.58 points for tests taken at 11 a.m.”


New SAT Stresses Reading Comprehension

“The College Board, which makes the SAT, is rolling out a new test — its biggest redesign in a decade, and one of the most substantial ever,” The New York Times reports. “Chief among the changes, experts say: longer and harder reading passages and more words in math problems.”

“The College Board said that the number of words in the reading section had remained the same — about 3,250 on the new test, and 3,300 on the old one — and that the percentage of word problems in the math sections of the old and the new test was roughly the same, about 30 percent … But outside analysts say the way the words are presented makes a difference. For instance, short sentence-completion questions, which tested logic and vocabulary, have been eliminated in favor of longer reading passages …These contain sophisticated words and thoughts in sometimes ornate diction.”

“College Board officials said the new test was devised to satisfy the demands of college admissions officers and high school guidance counselors for an exam that more clearly showed a connection to what students were learning in school. The College Board has also been grappling with complaints that the old SAT, with its arcane vocabulary questions, correlated with advantages like parental income and education, and that whites and Asians performed better on average than blacks and Hispanics.”
