Baseline neurocognitive testing was conducted pre-season in Grade 7 and post-season in Grades 8 and 9. Year-end academic grades were documented for Grades 6-9 and 12 (pre-high school to year of school leaving). A mixed model repeated measures ANOVA was conducted to investigate comparative neurocognitive and academic outcomes between the three sub-groups.Results: Compared with controls, both rugby groups were significantly lower on the WISC-III Coding Immediate Recall sub-test. There was a significant interaction effect on the academic measure, with improved scores over time for controls, that was not in evidence for either rugby group.Conclusions: Tentatively, the outcome suggests cognitive vulnerability in association with school level participation in rugby. © 2015 Taylor \& Francis Group, LLC.},
