--- - |2+ Objective Kenya's 1985 education reform implemented curriculum changes to prepare children for the job market and changed the instructional language from English to local ethnic languages during the first three years of primary education. This article examines the reform's impact on (i) level of education completed, (ii) income level, and (iii) preference for national versus ethnic interests. Methods Using survey data collected from randomly selected Kenyan citizens in Nairobi, this article uses a regression discontinuity (RD) design comparing the first cohort exposed to the reform to those who were not. Results The education and income levels of those beginning their education under the reform were higher. The reform did not influence preference for national or ethnic interests. Conclusions The reform partially increased children's job market preparation but was unsuccessful in addressing unemployment. Teaching children in local languages exhibited no negative effects on ethnic as opposed to national interests. - 'Social Science Quarterly, EarlyView. '
