Secondary Schools (KS3) Achievement and Attainment Tables 2006

This is a breif guide to understanding the achievement and attainment Tables and the value added score assigned to the key stage 3 results.

Please refer to the DCSF website (off site link) for the full explanations and diagrams How to read the Performance Tables (KS3) The Secondary School (Key Stage 3) Achievement and Attainment Tables give more than one measure of a school's performance. These measures can be considered alongside each other when evaluating the performance of a school.

The Tables show:

 The total number of children with a statement and % figure (SAP)

 The total number of children on School Action and % figure (SA)

 The % figure of children reaching L5+ and L6+ in English, Maths and Science

 A/T is the number of children absent or unable to access the tests.

 The LA average and England average can be used to form an opinion of the success of the school, in conjunction with looking at the value the school has added to the performance of the children.

How to read value added (VA) table

 An average point score is calculated for each pupils key stage 2 results in English, Maths and Science.

 The same average point score for each child is calculated from the Key stage 3 results.

 A median Key stage 3 value is created by comparing the performance of other pupils nationally who received similar or the same key stage 2 scores.

 The value added score is the difference between the key stage 3 result and the national mediun Key stage 3 result.

 The example below is a school with 4 pupils Pupil Pupil's KS2 average point score Pupil's KS3 average point score Median KS3 average point score for their KS2 average point score Pupil's VA score A 25 36 31 +5 B 25 29 31 -2 C 27 35 35 0 D 27 37 35 +2 Total of all individual value added scores = +5 +5 (the total) divided by 4 (the number of School's value added measure pupils) = 1.25

The school's value added measure will be presented as a measure based around 100. This is done by adding 100 to the score. The school in the above example would be shown as: 101.3 (rounded to one decimal place) Key Stage 3 Test Results 2006 Pupils eiligible for KS3 assessment with SEN English Mathematics Science Total with statements or supported at SAP supported at SA Average Point Score Number % Number % L5+ L6+ A/T L5+ L6+ A/T L5+ L6+ A/T LA Average 6.8% 9.2% 80% 39% 81% 64% 80% 50% 36.3 England 8.8% 11.2% 73% 34% 77% 57% 72% 41% 35.0 Average Denefield 215 7 3.3% 14 6.5% 74% 28% 6% 78% 51% 5% 68% 33% 5% 34.6 School The Downs 153 14 9.2% 7 4.6% 84% 50% 2% 82% 67% 2% 86% 63% 1% 37.5 School John O'Gaunt Community 95 6 6.3% 13 13.7% 67% 24% 2% 80% 49% 0% 91% 58% 0% 35.2 Technology College Kennet School 300 16 5.3% 22 7.3% 78% 28% 5% 84% 72% 2% 82% 51% 4% 36.8 Little Heath 260 4 1.5% 8 3.1% 86% 46% 2% 85% 74% 2% 84% 61% 1% 37.4 School Park House School and 223 14 6.3% 13 5.8% 87% 43% 3% 82% 68% 3% 84% 55% 3% 37.1 Sports College St Bartholomew's 299 12 4.0% 23 7.7% 93% 59% 2% 92% 77% 1% 91% 61% 2% 38.9 School Theale Green Community 226 17 7.5% 47 20.8% 79% 44% 4% 82% 62% 2% 83% 54% 2% 36.8 School Trinity School 189 16 8.5% 29 15.3% 78% 28% 8% 69% 40% 2% 63% 29% 3% 33.6 The Willink 157 5 3.2% 22 14.0% 76% 39% 1% 80% 66% 1% 81% 46% 2% 36.1 School Special

This is a breif guide to understanding the contextual value added score assigned to the key stage 4 results.

Please refer to the DCSF website (off site link) for the full explanations and diagrams What is CVA ?

What do we mean by contextual value added?

 CVA is not very different from simple VA. The basic principle of measuring progress from the KS2 test to qualifications attained at KS4 remains the same.

 A number of other factors which are outside a school's control, such as gender, special educational needs, movement between schools, and family circumstances, are also known to affect pupils' performance.

 CVA takes these factors into account to give a much fairer measure of the effectiveness of a school. That means that comparisons against other schools are more meaningful, for example, when comparing the performance of a school in a leafy suburb against the performance of one in an inner city area - both of which might face quite different challenges.

Contextual Value Added scores

 Each pupil's CVA score is based on a comparison between their best eight results at GCSE - and the typical performance of pupils with similar characteristics and similar results at KS2.

 If their GCSE (and equivalent) results are better than the average achieved by similar pupils, the CVA will be positive; if they do less well, it will be negative.

 All individual pupil scores, positive and negative, are added together and an average produced for the school.

 That average is then adjusted to account for the amount of pupils in the year group to give the school level CVA score.

 This score is then presented as a number based around 1000. This indicates the value the school has added on average for its pupils, given what is known about the circumstances of its pupil intake.

Interpretation of a school's CVA score

The CVA section shows, for each school:

 The KS2-KS4 CVA score. The CVA measure is shown as a score based around 1000. Scores above 1000 represent schools where pupils on average made more progress than similar pupils nationally, while scores below 1000 represent schools where pupils made less progress.

 The upper and lower limits of a 95% confidence interval;

 A coverage indicator; (The coverage indicator shows the percentage of pupils at the end of KS4 included in the CVA calculation.) and

 The average number of qualifications taken by pupils included in the CVA calculation.

A measure of 1006 means that on average each of the school's pupils achieved the equivalent of one GCSE grade higher in one subject than the average attained by similar pupils. A score of 1048 means that on average each pupil achieved one GCSE grade higher in each of their best eight subjects than the average attained by similar pupils.

A score of 994 means that the school's pupils achieved one grade lower in one subject on average, while A score of 952 means that pupils achieved on average one grade lower in each of their best eight subjects.

Confidence Intervals

 A degree of uncertainty should be taken into account if interpreting the figures as estimates of a school's effectiveness.

 The uncertainty of a CVA score as a measure of school effectiveness can be presented as a confidence interval.

 This is a range of scores within which we can be statistically confident that the "true" school effectiveness will lie.

 The CVA methodology produces a 95% confidence interval (CI) to show the range within which we can be confident the CVA measure represents the overall effectiveness of a school at KS4. If a school cohort is large the width of the CI will be small, but if a school cohort is small the CI will be wide.

 A school level CVA measure must always be interpreted alongside the confidence interval.

 Schools where the lower limit of the CI is above 1000 represent schools where pupils on average made significantly more progress than pupils nationally.

 Schools where the upper limit of the CI is below 1000 represent schools where pupils made significantly less progress. Examples are given in the box below.
