High Value Added at A Level

Recently received value-added data from our independent analysts confirms the impact on this year's A-level results of quality teaching across the School.

The chart below shows the value-added scores for A-Level qualifications for Ashford School since 2001. If a value lies within a shaded area, then the value can be deemed as 'normal' whether it is negative or positive. When the value falls outside the shaded areas that the value can be deemed significant, thus implying that some factor in the teaching and learning, external to the students, has contributed to the value. As you can see the value for 2011 falls outside both shaded areas indicating that Ashford School adds significantly to the attainment of the students.

 

In the second chart below, the background area is a normal distribution graph representing the distribution of the average value-added scores for A-Level qualifications from all schools. The black bar is the value-added score for Ashford School. A score of 1.0 represents a whole grade at A-level and this is, on average, the impact of the teaching and learning at Ashford School.
