[3][4] By 1945 the Country Day included grades 1 – 8 and had an enrollment of 56 students on a six-acre school site on Sardis Road in suburban Charlotte.

[9] Journalists found it likely that its enrollment benefitted from parents seeking to avoid busing in the public school system.

[12] In 1980 Country Day merged with Carmel Academy, one of several independent schools established in Mecklenburg County in the wake of the Swann decision in 1971.

[14][15] Cannon Campus for grades JK–4 and 9–12 has 15 buildings, including a full-service dining hall, two libraries, a 400-seat theater, two reading gardens, and multiple computer labs.

Country Day now has two active gyms, one for lower school PE, and another for varsity basketball games.

Grounds enhancements included a new entryway and fencing, a new front courtyard, and new tennis courts and practice fields.
