It is investigated whether the attendance of the schoolkindergarten pr
omotes literacy acquisition. 20 schoolkindergartenchildren, 20 childre
n of a control group and 155 children of a slightly reduced representa
tive group (comparison group) are compared. The schoolkindergartengrou
p does not differ from the control group in age, sex, intelligence, li
teracy prerequisites, literacy knowledge and behaviour variables. Scho
olkindergarten- and controlgroup both strongly differ from the compari
son group in their literacy prerequisites. During schoolkindergarten y
ear the literacy prerequisites and literacy knowledge improved only pa
rtially. In the first school years the literacy achievement of the sch
oolkindergartenchildren does not exceed literacy achievement of the co
ntrol group. Achievements of both groups are inferior to the compariso
n group. Possible reasons for the no-promotion-effect are discussed.
