Colegio San Andrés is a private school located in Lima, Peru.

In 1919 the primary school expanded into secondary education as well, changing its name to Colegio Anglo-Peruano.

Through the initiative of Dr. W. Stanley Rycroft and with the collaboration of Dr. Alberto Arca Parró, a distinguished teacher at the school, the Leader magazine was founded in 1926.

In the words of its first editorial, the Leader aspired to "be the voice of educational development, and be able to unite the voice of teachers and students in the process of development and reinterpretation of the basic principles of teaching."

In 1942, in compliance with the dictates of Government Resolution N°3, announced by the Ministry of Education, the school changed its name again, becoming the Colegio San Andrés.
