Community is an important aspect of the ethos at Eltham. The College community is far larger than just pupils and parents. Pupils are encouraged to help in the larger community by taking part in community service in year 12, working in local schools, nursing homes and on various other community support projects.
The school is a Kent County Cricket Centre and shares many of its facilities with other schools in the area; it is a training centre for teachers in the south east; and, its orchestra, ECCO (Eltham College Community Orchestra) plays each year to fund charitable giving.
Each year the school is involved in a number of charity events, from the Staff Reveue to a home grown version of Stars in their Eyes and a number of highly successful fashion shows!
