Are we doing something wrong?

I have just come across a set of statistics regarding Narrowing the gap between the lowest achieving 20% in the Early Years Foundation Stage Profile and the rest.

In England between 2005 and 2010 the gap between the lowest achieving quintile of children and the median child in England fell from 38.9% to 32.7%.

In the South West Region the gap fell from 35.9% to 30.3%.

In North Somerset LA the gap fell from 33.7% to 32.3%.

So, our gap was a lot smaller than the national average to begin with, and our gap is now below the improved figure. Which is good.

However, do these figures beg us to work harder still? To be more innovative? To somehow find a way to make the gap even smaller still? I don't want to jump to conclusions based on statistics alone, but they do lead me to question why our figures have only improved by just over 1% when the figures of the South West region and England as a whole have improved by over 5%.

How to narrow that gap is a question with an infinite number of answers. Answers I am only just starting to learn about.

I hope I can look back on this very first post at a point in my future career and be able to see that we have narrowed that gap further.
I hope when I ask how to narrow the gap my mind is filled possibilities, but even more importantly, evidence of how we have done so.
