Tat Wood notes that in this story, which most viewers interpret as being set shortly after the events of "An Unearthly Child", Coal Hill School has a school uniform. From this and other evidence in "Remembrance of the Daleks", such as the fact that it is broad daylight at 5:15 pm, Wood hypothesizes that "Remembrance" is actually set in the summer of 1963, prior to the events of "An Unearthly Child", with the school's uniforms being phased out in the autumn term.
