The Flynn effect has been widely researched in Western and European nations, while it has been comparatively understudied in Asian countries. This study examines possible Flynn effects in China from 1985 to 86 and to 2011–12. Results are reported for an IQ increase among 12year olds on the Full Scale IQ WISC-R (Wechsler Intelligence Scale for Children-Revised) of 6.19 IQ points, a gain on the Performance IQ of 6.55 IQ points, and a gain on the Verbal IQ of 1.91 IQ points. •Flynn effect has been relatively understudied in Asian countries.•This study examines possible Flynn effects in samples of Chinese children.•We found FIQ increased by 6.19 points, PIQ by 6.55 points, and VIQ by 1.91 points.•Our study suggests that the Flynn effect is present in Chinese populations.
