 Wirral Education Authority rationalised their middle school system in 1982, and added an extra year to primary schools (Now referred to as Year 6) and two years into secondary schools (Years 7 and 8).To accommodate these two extra years Olderhaw was expanded to include a Lower School (Opening in September 1982), under K. R. M. Williams, at the site of the old St. Hilda's School in Ormond Street; it was later moved to the same site as the main school in time for the autumn term of 2000, and the Lower School site was demolished to make way for new housing.The current forms of the school are Fir, Oak, Cedar, Maple, Poplar and Elm although in recent years Poplar has been replaced in favour of the form Beech.
