St. Teresa's High School (STHS) is a government aided, private co-educational day school, located at Charni Road in Mumbai, India. The institution was founded in 1843, and present day school building was established in 1924.
The school caters to pupils from kindergarten up to grade 10 and the medium of instruction is English. The school is affiliated to the Archdiocesan Board of Education, Mumbai, which conducts the Maharashtra State Board of Secondary and Higher Secondary Education examinations at the close of class 10.
The school campus comprises three separate buildings and features three playgrounds: a mud ground, a stone ground, and a quadrant. The main school building has four floors.
The ground floor contains classrooms for Junior Kindergarten (Jr. KG), Senior Kindergarten (Sr. KG), and grade 1, along with facilities such as the assembly hall, school church, school office, computer lab, drawing room, the MDR AV Hall, Manager's Office, Head Mistress's Office, and the newly added e-library.
The first floor contains classrooms for grades 2, 3, and 4, as well as division B of grade 10, which was relocated to the second floor in 2019. Additionally, this floor houses laboratories.
The second floor contains classrooms for grades 4, 5, and 9, along with division B of grade 10, as aforementioned. Other facilities on this floor include the Supervisor's Office, the school library (formerly known as the G.M. Room), the staff room, and the Principal's Quarters.
The third floor accommodates classrooms for grades 6, 7, and 8, as well as another staff room and school library.
The admission notice for Junior kindergarten is put up in January. During the admission procedure, preference is given to Catholics and siblings of former students.
The school follows the Maharashtra State Board of Secondary and Higher Secondary Education syllabus. English is the medium of instruction; Hindi is taught as a second language, and Marathi is taught as a third language.
The academic year, which commences in June and concludes in April, is segregated into first unit test, first term, second unit test, and second term. The first term is from June until November and the second term is from November until April. The results of these terms are first shown to the students, and after that to the parents on the open house days; the report of the pupil's performance is presented to the parents after the completion of a term. Tests are conducted periodically and examinations are held at the end of every term. The courses of studies extend from kindergarten to grade 10, at the end of which students appear for the SSC Examinations. The school's students have consistently performed well at the SSC examinations and the school has maintained a 100% passing-rate.
Emphasis is placed on extracurricular activities. Inter-house debates, elocution, dramatics and sporting competitions are also a part of the cultural lives of the students. The school also takes part in science exhibitions and quizzes conducted.
The house system aims to cultivate a sense of collective responsibility and unity among students while also serving as the focal point of school life. Students from different houses engage in friendly competition through sports and various co-curricular activities. Each house is overseen by a Students' Council member who is responsible for fulfilling their duties as directed by the management or school staff. The school houses and their respective colours are as follows:
Nehru Gandhi Tilak Tagore.
Students from grades 1 to 8 are required to wear blue short-sleeved shirts with white stripes, paired with blue short pants. Boys in grades 8 to 10 transition to blue long pants, while girls wear a blue six-piece skirt with a white blouse. Regular black leather shoes are part of the standard school attire, with ties and t-shirts provided by the school.
On days designated for Physical Education (P.E.), primary section boys wear black short pants and t-shirts in their respective house colours, while girls wear black skirts and house-coloured t-shirts. Older students also wear black long pants and house-coloured t-shirts for P.E. sessions.
The P.T.A. aims towards at fostering cordial and friendly relations between the members of the staff and the parents of the students so that there is better understanding and co-operation between the home and the school. From each class, one parent is elected as the P.T.A. representative of that specific class.
The Head Boy and Head Girl are chosen by the teachers from among the students in the grade 10; the Assistant Head Boy and Assistant Head Girl are selected from the grade 9. Additionally, four House Captains are appointed for each house. The Captains of the house are selected from the grade 9, while the Assistant Captains are chosen from the grade 8. The election of the members is done by the teachers' staff.
St Teresa's is a cosmopolitan school. The school imparts Christian values to the children. The Christmas concert is celebrated every December. A sports meet and a farewell party for students who are passing out of the institution are also held annually.
The school also holds some traditions to be maintained by all the students of the school; they are mentioned in the school diary. They are:[2]
