Old Caldeian Union

We welcome former students of Calday Grange Grammar School.

Our alumni may become members of the Old Caldeian Union (OCU) which has been established for many years.

We seek to provide friendship among former students, to afford a ready means of communication between them and to maintain a connection with the school. In addition we welcome their support to help advance the welfare of the school, for example through supporting students by undertaking careers talks.
