“…The magnitude of score effects is quite similar over the three cohorts and at the upper end of or above the interval of estimates reported for the SAT (Bond, 1989;Cole, 1982;Donlon, 1984;Messick, 1980;Powers & Rock, 1999), and the SweSAT (Gustafsson & Benjegård, 1996;Henriksson, 1985Henriksson, ,1991Henriksson, , 1993Henriksson, , 1995Henriksson & Bränberg, 1992, 1994. Whereas the present result may be interpreted as a practice effect, the estimated gain in scores presented in most studies referred to above represents a combined practice and about six to seven month growth effect.…”
