The Holy Angels' Convent Higher Secondary School is one of the oldest educational institutions in the city of Thiruvananthapuram, the capital of the Kerala state in India.
This school for girls was opened on 10 November 1880 by Mother Elias from Ireland.[1] She was the foundress of the Congregation of the Carmelite Religious (C.C.R).
In 1888, the school secured the honour of being the first girls' school in South India which presented students for the Matriculation Examination of Madras University. In 1896, the school was upgraded to a second-grade college. But this college section was closed in 1906.
The school boasts of a strength of over 6000 students, mostly girls. Admission to the boys is restricted up to the IV standard. Even though both Malayalam and English are used as the medium for instruction, senior students speak only English within the campus. The school has a library of over 20,000 books, fully equipped and upgraded computer labs, laboratory facilities, huge sprawling buildings and beautiful gardens. Boarding facilities are also available here.
This school has a house system which includes four houses; Blue, Green, Yellow and Red. This housing system increases the efficiency of students in curricular as well as extracurricular activities.
