We went to Wilsons and Wallington. Somewhat earlier, it must be said, than strictly necessary but wanted to get DS to appreciate the journey ahead.
Very difficult to split the two but:
Wilsons - made a huge play on anti bullying, amazing IT curriculum (coding and programming robots - really impressive), umpteen football pitches and astro turf (v important for son), new music endowment to fund music instrument lessons for each pupil, and fantastic art faculty.
Wallington- great emphasis on the pastoral side, excellent science, lovely buildings and campus feel, laid back and pleasant, excellent alumni involvement for university applications and very good science facilities. Downside - no IT as this has been dropped for food technology - not good.
On balance I would opt to go with Wilsons but they are both really strong. Wally is more unstructured, slight less organised and Wilsons very much a well oiled machine.
Thankfully we have two more years To go until a decision needs to be made.
