Park, G., Lubinski, D., & Benbow, C. P. (under review). When less is more: Effects of grade skipping on adult STEM accomplishments among mathematically precocious youth. (2011)

'Summary:
Results from each phase of this study are supportive of key hypotheses of the
time-saving theory (Pressey, 1946b), suggesting that grade-based acceleration, appro-
priately applied with mathematically precocious individuals, can have lasting e ects
on the productivity of those pursuing STEM fi elds. The fi rst phase, summarized by Fig-
ure 6, reinforces past fi ndings in the acceleration literature (e.g., Flesher & Pressey,
1955; Pressey, 1967; Swiatek & Benbow, 1991; Wai et al., 2010; Bleske-Rechek et
al., 2004). As in these previous studies of grade-based acceleration, grade skippers
were more likely to pursue advanced degrees and reach important career milestones
related to success in STEM careers, such as STEM publications and patents. The
current study not only replicates these ndings, it strengthens them by finding simi-
lar patterns of results under the much stricter methodological controls granted by the
matching procedure.'
