A singular Transition year for young boys.

In 1989 Gilman added a rather novel new grade: a "pre-first grade" for boys who had completed kindergarten and needed a year to boost independence and academic readiness before first grade. Though the concept gained traction in the independent school educational community, the idea was, at the time, relatively new to Baltimore.

Today, prep-one thrives at Gilman, and remains a viable option for boys who require a little extra preparation after kindergarten. In this singular transition year before first grade, boys learn to read and write, add and subtract, and gain the confidence they need for future academic success.

Eventual 13-Year Men across divisions join the pre-first class and founding teachers Diane Rogers and Dia Matthews. Also pictured is Middle School teacher Chris Bendann '03, who was a member of the inaugural pre-first class.
