The working party was first set up in December 1965. In the spring term of 1966 some 22 primary schools with large numbers of immigrants were visited and long discussions held with head teachers and staff. It was then decided to collect written information from all the Authority's schools containing juniors and with more than one third of their total roll, immigrants. The 52 schools surveyed included 21 junior mixed schools, 30 junior mixed and infants' schools and one junior girls and infants' school. The sample had a higher proportion of West Indian pupils than the Authority's primary schools in general. Indians, Pakistanis, and Cypriots were represented in fairly typical proportions, but the "other" immigrants were under-represented. About a third of these latter groups in the sample schools were Europeans, one-third Africans, one-fifth Guyanese and the rest from various countries. Data was obtained on year of entry to education in the United Kingdom for all immigrant pupils in the sample who were due to transfer to secondary schools in 1966. An attempt was made to see whether the data on year of entry for individual pupils show any relationship with other information about them in the "leavers schedule," and especially with attainment and verbal reasoning groups in the secondary transfer profile.
