School-level annual school census: guide to submitting data

SLASC is an annual, statutory census that takes place every January. You must complete statutory censuses by law unless there’s a good reason not to.

SLASC collects the following information about registered independent schools:

their contact details
the number of pupils on the attendance register
the number of teaching staff
the courses of study
the number of pupils with special educational needs (SEN)
the number of pupils in local authority care
annual fees
details of accommodation
the number of staff members who have joined or left since the last census
the school’s proprietors

Do not confuse SLASC with the Independent Schools Council annual census, which also takes place in January each year.
