Local Authorities (LAs) are required under section 251 of the School Standards and Framework Act 1998 to prepare and publish a budget statement before the beginning of each financial year for that year.
These statements should outline what the LA plans to spend on education services.
The exact formats to be used for this financial reporting are prescribed by the Secretary of State.
Schools block data file 2013-2014 can be found at the Department for Education's website. For Slough details filter the data by choosing Slough from the second column header called 'Local Authority Name'.
