The study, by the Sutton Trust, has found how rates of free school meal (FSM) eligibility in schools compare to their local areas.
It has calculated each school's FSM gap, which is the difference between the FSM rate of a school’s intake and the FSM rate of its catchment area.
A negative FSM gap indicates the school’s FSM rate is lower than the FSM rate of its catchment area, while a positive FSM gap that indicates the school’s FSM rate is higher.
BristolWorld has ranked the 21 local secondary schools based on the difference in percentage between their FSM rates and those of their catchment areas, from the largest negative difference to the largest positive difference:
