From Reception to Year 8 pupils are allocated to one of two houses during the final weeks of September; Henwood which is green or Lawson which is blue. The skills, aptitudes and abilities of each child are considered to ensure that the division is balanced within year groups and across the school, and leads to a highly competitive competition. The pupils compete for the infamous Bison Trophy.
Throughout the year there are House Competitions. The various elements of these Competitions reflect the overall curriculum of the school and include academic, artistic and sporting activities.
