Threshold payments of £229 are payable in addition to the latest rates shown in each column. London weighting and social priority school allowances are excluded from these figures.

asked the Secretary of State for Education and Science what is the average pre-tax salary of university teaching staff in the United Kingdom compared with comparable salaries in Canada, Germany and France.

The current average salary for university teaching staff, inclusive of threshold payments, is estimated to be £4,750. Information about comparable salaries in Canada, Germany and France is not available.

asked the Secretary of State for Education and Science how many university teachers have left the United Kingdom to work at universities abroad in each of the last five years.

150 in the 1972–73 academic year and 196 in 1973–74. These figures exclude clinical staff. I regret that information about earlier years is not available.
