Our school is named in honor of Miss Dorothy Dalgliesh, a kind, considerate and very gracious lady who taught in the Lethbridge Northern School District for many years, including several at this school..
The present building was opened during the 1954/55 school year. At that time it housed grades four through seven. It was named Crescent School, a name it retained until 1967 when, during Canada's Centennial, the name was changed to Dorothy Dalgliesh School.
In the fall of 1959 the original Dorothy Dalgliesh School, which housed grades one through three, was closed and its students transferred to the present Dorothy Dalgliesh School. It served grades one through seven until the fall of 1968 when it became a school for grades one through six. In September of 1985, Kindergarten was added to the school's program.
In June of 1997, renovations to the entire building began, and a new Gym was added to the west. A new updated Computer Room, Library and Kitchen were included in the renovations
