2012 and the school is a primary school only, and in our experience primary schools tend not to erect memorials to their "old boys". But we found, at Martin Watson, "...when I started school in 1951, Stanley Road schools taught Infants, Juniors and Secondary boys. The Secondary Boys school was called Waldegrave...". So it is probably that it was a secondary school during WW1. The school's website has a history page "coming soon". When that arrives it might clarify.
