Radboud Early Academic Development Inquiry (READI) project; "Precocious reading / math" paper

This collection includes (meta-)data related to the first publication of the Radboud Early Academic Development Inquiry (READI) project. The READI project is a longitudinal project on children's early cognitive, literacy, and numeracy development from kindergarten to second grade ("groep 2" until "groep 4"). Children were repeatedly assessed across five time points (N = 224 at TP1; N = 205 at TP5). Cognitive skills/domains that were assessed include: phonological awareness, letter knowledge, vocabulary, word reading fluency, rote counting, symbolic comparisons, number line estimation, applied math, arithmetic fluency, verbal working memory, visuospatial working memory, non-verbal reasoning, and rapid naming speed (RAN). Children were tested individually, in a quiet room at their school. Parents completed a parental questionnaire about the home learning environment at sign-up. This collection belongs specifically to the first paper, in which we assessed the cognitive and home-related predictors of 'precocious' (i.e., early advanced) reading and/or math skills at the first time point, in kindergarten.
