“A Decade of Longitudinal Research On Academic Acceleration Through the Study of Mathematically Precocious Youth”, 1993 (; backlinks; similar):
Over the past decade, several longitudinal studies pertaining to the education of intellectually gifted students were produced through the Study of Mathematically Precocious Youth (SMPY). One area that was emphasized, in keeping with SMPY’s history, is academic acceleration.
SMPY’s studies, which consider various groups of students, methods of acceleration, and types of outcomes, support acceleration as an educational method. Their results are in keeping with the work of other authors in this area. In this article, the subjects, methods, and outcomes of SMPY’s studies are described and plans for future research are outlined.
