quantitative molecular genetic research requires large samples provide adequate statistical power expensive test large samples person especially participants widely distributed geographically increasing access inexpensive fast internet connections makes possible test large samples efficiently economically online reliability validity internet testing cognitive ability previously reported issues especially pertinent testing children developed internet versions reading language mathematics general cognitive ability tests investigated reliability validity 10 12yearold children tested online 2500 pairs 10yearold twins compared scores similar internetbased measures administered online subsample children 12 years old 759 pairs within 3 months online testing 12 years administered standard paper pencil versions reading mathematics tests person 30 children 15 pairs twins scores internetbased measures 10 12 years correlated 63 average across two years suggesting substantial stability high reliability correlations 80 internet measures inperson testing suggest excellent validity addition comparison internetbased measures ratings teachers based criteria uk national curriculum suggests good concurrent validity tests conclude internet testing reliable valid collecting cognitive test data large samples even children young 10 years
