"Form S3 is completed by or on behalf of the appropriate authority for the school to indicate the extent to which it meets the requirements placed on it by statute. If completed on paper, Form S3 is returned to the registered inspector.
Form S4 is completed by the headteacher and is used to summarise the school's self-evaluation. If completed on paper, Form S4 is returned to the registered inspector"
While it is vital that the governing body knows what is in S4 and is able to cite the school's strengths and weaknesses (or more correctly areas identified for improvement), it is form S3 that the governing body should be most familiar with. Governing bodies have a statutory requirement to ensure that certain policies and procedures are in place in school. For example a racial equality and sex education policies to name but two. A full list of responsibilities is set out in the Guide to the Law for School Governors. It is in form S3 that these responsibilities are accounted for.
Guidance notes on completing forms S3 and S4 are available on the OFSTED web site.
