However, the rule relating to student immigration under which the husband of a female student was admitted to the United Kingdom without the right to work while the spouse of a male student was admitted without that restriction had been maintained because of the real danger the abandonment of that restriction would represent for the United Kingdom's economy. 12. As far as the number of women refugees in the United Kingdom was concerned, she could only provide total figures but would send the Committee gender-specific figures at a later date. 13. With regard to article 10, she replied to a question about government-sponsored facilities for children under five by noting that government expenditure in that area had increased by 50 per cent since 1980 and that the number of children served by maintained schools was growing. The Government had no specific policy on retaining single-sex schools or the teaching of certain subjects in a single-sex setting. However, there was still some demand from parents for single-sex education for girls. The Government itself was not financing any research projects to evaluate the effects of single-sex education, but the Equal Opportunities Commission had studied the teaching of science and engineering, and Her Majesty's Inspectors were currently conducting a study which compared the teaching of mathematics in single-sex and co-educational classes. While the Government had accepted the Cockroft report and supported a number of initiatives aimed at improving pupil achievement in mathematics, the Inspectors seemed to think that more radical changes were required in the approach to that subject. The Inspectors were also concerned about instances of latent, unintentional discrimination, referred to as the "hidden curriculum" in the report. All those issues would be covered in the new teacher training programme that was to begin in September 1990.

It mentions the economy, student immigration, single-sex schools, and government expenditure on education, which suggests that the text is more focused on internal affairs and policy-making rather than international trade or humanitarian aid.
