Question - What does query 1260Q mean?
Answer - Query 1260Q relates to the teacher and support staff to student ratio.
The ratio for nursery is (<Home Pupils> plus <Guest pupils>) should be less than or equal to 13 times (<Teachers> plus <Non teachers>).
Take a look at the example:
The ratio works out as (27 + 0) should be less than 13 x (2 + 0) = 26. We can see that the number of pupils is 27 which is greater than the number of teachers plus support staff (26).
