Holy Trinity High School history

The cornerstone was laid for Rosary College on June 6, 1920.

By 1922, Rosary House was a four year high school with their first graduating class of twenty-eight.

In 1924 the sisters purchased one half of the block at Division and Lathrop just down the street from Rosary House.

The new school could accommodate 450 students.By 1925 Trinity consisted of the previously mentioned 275 students, thirteen sisters and two lay teachers.The new school included classrooms as well as science labs, a library, an indoor gymnasium-auditorium, chapel and convent.

There now were four clubs, Athletic, Dramatic, Camera and Annual (Yearbook) as well as the newly formed RHS Alumnae Club.Long before 1926 it became evident that a new and larger school was needed.

In September 1940, ground was broken for the new addition of a west wing to the school.

In 1953 the school was relocated to properties owned by the Roman Catholic Archdiocese of Kingston at 18 Emerald Road (now George Headley Drive) and renamed after the Holy Trinity Cathedral on North Street in Kingston.

In 1956, THS participated, for the first time, in the National Merit Scholarship program.

Currently 90% of Trinity’s full-time IB students have earned an IB Diploma as compared to the national average of 80%. More about our academic programs…Block Scheduling, a new type of scheduling based on the collegiate model, was inaugurated in 1995. It was the first building constructed on Trinity’s grounds since 1962.

By the end of the 1970’s the school population grew to over two thousand.

In 1995 keeping with the Ministry of Education school rationalization programme the school was upgraded to a Comprehensive High school and renamed Holy Trinity Comprehensive High school and saw the first batch of Common Entrance students being admitted.

Trinity was the first Catholic school in the Chicago Archdiocese to offer this program.Trinity anticipated the next millennium in 1998 by updating their technology tools.
