Turn off motorway at junction 11, the main A33 exit - not the A329M or A4 exits (junctions 10 and 12). At the roundabout, take exit for B3270 Earley and Shinfield. Follow this road for about half a mile. At the junction with A327, turn left towards Reading. Now follow Shinfield Road, going straight ahead at two mini-roundabouts in a small shopping area. You will soon see, on your right, tall trees and some minor entrances to the school grounds. After another half mile, the main entrance is on your right, just before the traffic lights.
