Abstract	This study investigates the comparability of IQ scores. Three cohorts (1933/36, 1997/98, 2006) of Estonian students (N = 2173) are compared using the Estonian National Intelligence Test. After 72 years the secular rise of the IQ test scores is 0.79 SD. The mean 0.16 SD increase in the last 8 years suggests a rapid increase of the Flynn Effect (FE) in Estonia. The measurement is not strictly invariant, which means that the IQ scores of different cohorts are not directly comparable. Less than perfect comparability of test scores is caused by at least two factors: time between measurements and societal/educational changes between cohorts. As was to be expected, the meaning of subtests and the meaning of the "g" score have changed over time. (Contains 7 tables.) (As Provided).
