The College celebrates its 50th Miss Dorothy Knox also celebrates 30 years as Principal at the College. When she commenced, there were 339 students. By 1966 there were 1,280.

Miss Knox is quoted as saying, “Since the foundation of Pymble 6,600 girls have passed through the school, and 1075 are here at present with another 221 at Ingleholme. You all have a great tradition to pass on to those who follow. It is worth keeping. We have a tradition of academic distinctions, good sportsmanship and, above all, friendliness and courteous behaviour. These are all qualities of which your predecessors were proud and hope that you will carry on attitudes established and nurtured over the years. May the next fifty years of Pymble be ever more joyous and prosperous.”
