The 60mm monofilament D-Vision artificial surface from Desso Sports Systems was chosen due to its soft natural appearance and high water characteristics.
The £550,000 project was funded partly through a £245,000 grant from the Football Foundation and fundraising by the school.
As a result of a relic under the school grounds and concerns from residents over flood lights, the original proposed site for the pitch was changed.
The Environment Agency also raised concerns over flooding and the school were unable to raise the height of the pitch.
Assistant head teacher Roland Davey said: "The relic is a bit of a nuisance; historically it has been classed as a Roman monument but recent research has show it could have been made near the bronze-age, but we still had to hand-dig the holdings for the flood lights, because the machines may have ruined or damaged the monument."
Commenting on the new pitch, he said: "This is a much needed training facility for the school and it will be used by so many children and groups, boys and girls.
"Obviously it is good for Matthew Arnold School but also for the surrounding areas as well. It is world class."
