In May 1967 the government made a decision to 'take account of a fee income of £250 a year from students outside the United Kingdom' beginning with the 1967-68 intake. The Council for Scientific Policy, concerned that this might discourage overseas students, sent a circular letter to various organisations, including the Institute of Animal Genetics, seeking to collect evidence of the effects of fee changes on postgraduate research students for the attention of the Secretary of State.
