The Tables show the levels of overall and persistent absence for day pupils of compulsory school age (age 5 to 15 at the start of the academic year 2007/2008).
Overall absence is the percentage of possible half-days recorded under any combination of the following attendance codes (or the sum of authorised and unauthorised absences for schools which do not report absence by reason):
Persistent absence is the percentage of pupils enrolments equalling or exceeding the threshold number of half-day absences (set to equal 20% of the national average number of possible half-day sessions) over the Autumn and Spring terms combined. The persistent absence threshold for Autumn and Spring 2007/20008 is 48 or more half-day sessions.
Boarding enrolments are not included. Enrolments for whom zero possible sessions were recorded are not included. The first and second columns show:
If we have not received complete information from a school, “Valid data were not returned" is shown in the relevant columns. If we have agreed to suppress information from a school due to data quality issues, “Valid data were not returned” is shown in the relevant columns. “Not applicable” applies to boarding schools with no day pupils. In the case of schools that are part boarding, the published statistics relate only to the school’s day pupils and may not represent the levels of absence in the school as a whole.
There may be inconsistencies for some schools in the figures for the number of pupils on roll on 17 January 2008 and the number of pupil’s enrolments underlying the persistent absence figure. This is because they have been calculated in different ways and serve different purposes.
The Tables show how the KS2 results of pupils in each maintained school have changed over the past four years.
Bar charts show the aggregates of the three percentages of pupils achieving Level 4 or above and Level 5 in the English, mathematics and science tests in each of the years 2005, 2006, 2007 and 2008.
The Level 4 and above aggregate is calculated as follows:

= Aggregate (to the nearest whole number)
The Level 5 aggregate is calculated as follows:

= Aggregate (to the nearest whole number)
From the bar charts, you can see the history of a school's KS2 results, and whether they have stayed at the same level over time.
Because each year group is made up of different pupils, with different prior attainment and other characteristics, results may fluctuate from year to year for reasons to do with the pupils rather than the school.
Small fluctuations from year to year are unlikely to be significant, particularly if the school's year group is small.
The Tables show:
SCHOOL ACTION
The triggers for intervention through School Action could be the teacher's or others' concern, underpinned by evidence, about a child who, despite receiving differentiated learning opportunities:
SCHOOL ACTION PLUS
The triggers under School Action Plus could be that, despite receiving an individualised programme and/or concentrated support under School Action, the pupil:
