In 2012, the head of AP Grading, Trevor Packer, stated that the reason for the low percentages of 5s is that "AP World History is a college-level course, & many sophomores aren't yet writing at that level." 10.44 percent of all seniors who took the exam in 2012 received a 5, while just 6.62 percent of sophomores received a 5.
The second, and possibly more important point, is whether the "distance" between each successive item category is equivalent, which is inferred traditionally. For example, in the above five-point Likert item, the inference is that the 'distance' between category 1 and 2 is the same as between category 3 and 4.
In 2018, when the AP World History exam was discontinued, the College Board announced their commitment to developing two replacement courses, AP World History: Ancient and AP World History: Modern, but so far only the Modern course has launched, with the Ancient course still in development.

Symptom and attitude tests are more often called scales. A useful psychological test/scale must be both valid, i.e., show evidence that the test or scale measures what it is purported to measure, [1] [4]) and reliable, i.e., show evidence of consistency across items and raters and over time, etc.
The most widely used individual tests of cognitive abilities, such as the current editions of the Wechsler Adult Intelligence Scale and the Stanford–Binet Intelligence Scale, [14] report cognitive ability scores as "deviation IQs" with 15 IQ points corresponding to one standard deviation above or below the mean. Stanford–Binet Intelligence ...
[60] The same authors in a more comprehensive 2008 study, again on Danish male conscripts, found that there was a 1.5-point increase between 1988 and 1998, but a 1.5-point decrease between 1998 and 2003/2004. [61] In Australia, the IQ of 6–12-year-olds (as measured by colored progressive matrices) has shown no increase from 1975 to 2003. [62]
Both studies found high scores (>5) in F-Scale. However, the Coulter study also found the Communists scored higher in F-Scale than the politically neutral group. Eysenck (1954, ref. by Brown, p. 80) commented that Coulter's results indicate that the F-Scale actually measures general authoritarianism, rather than fascist tendencies in particular.
