The Ijebu Muslim College Old Students’ Association, IMCOSA, officially formed in 1956, has gone through stages of metamorphosis, finally stabilizing as a federation of Sets. Although each Set has its officers and holds meetings as deemed necessary, the National Body of the Association organises programmes and functions which are mutually agreed upon by the Parliament and all Sets participate.

In the last four decades, the body has been the leading partner among stakeholders in the continual academic and infrastructural development of the School.

The Ogun State government, in 2018, adjudged IMCOSA as the ‘Best Old Students’ Association in Ijebu Block”, applauding the untiring efforts of its members in building on the legacy of the founding fathers of the College, who, with meager resources, established an institution that towers above its contemporaries and has justified the labours of its heroes past.
