The Old Crescentarian Society was established in 1979 by Seikh Muin-ud-Din the then principal of Crescent Model School, taking into consideration the earnest desire of the old students to have an organization of the alumni so as to make collective efforts for the betterment of their alma-mater.

The first meeting of the Old Crescentarian Society was convened in 1979 by Sh. Muin-ud-Din. Mr. Shamshad Muhammad Lodhi was given the task of farming its constitution. Since then meetings of the Society have been held from time to time; and annual dinners have been arranged.

The Society has been raising funds to donate to School Library and awards gold medals to the students getting top positions in the Secondary and Higher Secondary examinations. The Society also offers a number of Scholarships for the students of Secondary, Higher Secondary and Girls sections of the School.

The Society published a comprehensive directory in 1990 which includes the particulars of all the Old Students of this school. The Society also Plans to take some other measures for the welfare of the institution.

The Society celebrated the silver jubilee of Crescent Model Higher Secondary School in 1993 by organizing number of functions, which will be remembered for years to come.

It is expected that the Golden jubilee of Crescent Model School is to be celebrated in 2018; and the Old Crescentarian Society will make it a point to do its level best in making it a real success.
