Look how things have changed at Bannockburn Primary School.
The photograph below shows a class of children on the Manor Way site from 1923. Notice that the children are placed in rows; the rows at the back are higher than those at the front.
Each week the children would be tested on their reading, writing and arithmetic (The Three R's). Those children who achieved the best scores would be seated at the back, on the highest row of seats. Those children who achieved the lowest score would be seated on the lowest row right at the front. This type of organisation is where the expression, 'Top of the Class' comes from.
