In 1963–65, he chaired a committee of experts bearing his name that recommended a radical reform of the entire Israeli education system.[2][9] Its suggestions included making preschool enrollment universal for disadvantaged children, shortening elementary school to grades 1–6; admitting all pupils without tests into integrated junior high schools (grades 7–9), raising the age of free compulsory education to fifteen (later raised to eighteen), establishing two-year and three-year comprehensive schools that provided a choice of tracks towards either a vocational diploma or a matriculation certificate, further integrating students of different skills and social classes, and establishing a new curriculum division in the Ministry of Education and Culture. The plan was approved by the Knesset and government, which allocated substantial resources to it, and the program began to be implemented in the summer of 1968.[9]
