The Harris Girls lottery isn't truly random. It is banded. I've pasted the appropriate part of the Harris Girls policy below. The logistics of running a banded lottery without using computer selection strike me as being mind-boggling, so I would assume that it is a computer programme that blindly allots the places, and therefore random in that respect.
This does NOT appear to a new system introduced this year. According to their archived admissions policies, the policy was approved in March 2015 and first used in the 2016 round, for entry in September 2017. That would make this the second year of operation.
d). One third of the remaining places available in each band ( rounded up the next whole number) will then be allocated to those living nearest to the Academy as calculated by straight line distance from the studentís home to the road junction of Shelbury Road and Colyton Road and living no more than 1 kilometre away from that point. Any applicants not allocated a place on this basis will be added to those awaiting random allocation as set out in e) below. Any places not filled by this distance criteria will also be added to the available places in each band to be filled by random allocation;
e) Random allocation: any remaining students who have sat the admissions test and have not been allocated a place will be selected for a place in each band through a random allocation procedure until each band is full. Should any band not be full at the end of this process, students from the nearest adjacent band will allocated using random allocation to fill the unallocated places, alternating between the band above and below. The random allocation will be verified by a person independent of the Academy who will certify that it has been carried out properly and fairly.
