I would like to know the highest relevant subject qualifications of maths teachers in secondary school and those in other subjects.
We said
The information requested for the qualifications of teachers by subject is not published by ONS, but is collected as part of the Labour Force Survey, a survey of households.
The ONS provides a bespoke service for analysis that is not already published on our website and the contact details are below. There will be a charge for this service. Information is available at: http://www.ons.gov.uk/ons/about-ons/business-transparency/freedom-of-information/what-can-i-request/index.html

As this information is already available to you via this route, we considers that s.21(1) applies to this request and the information does not have to be supplied under the terms of the Freedom of Information Act. s.21(1) is an absolute exemption and no consideration of the public interest test needs to be applied.
