Our Lady of Mount Carmel Girls Senior High School was borne through the initiative of Most Rev. Mathew Kwasi Gyamfi, the Bishop of Sunyani Diocese in conjunction with the sisters of the Handmaids of the Holy Child Jesus (HHCJ), and supported by the then St. Paul's Catholic Church, Techiman. The pioneering work in establishing the school was began by the late Msgr. John Oppong Baah, who was the first Ghanaian Parish priest of the then St. Paul's Parish. Msgr. Boakye Gyan and V. Rev. Fr. Peter Yeboah worked hard to bring the dream and vision of the school into reality. The school started in a temporary structure of the former St. Paul's Technical school with one hundred and fifty students. It was officially opened on 26th October, 2006. With the creation of the Techiman Diocese in 2008, the school came under the proprietorship of Most Rev. Dominic Yeboah Nyarko, the Bishop of Techiman Diocese.
The first headmistress was the late Sr. Veronica Adu Fosu (HHCJ) with Sr. Catherine Acquah (HHCJ) as the Assistant Headmistress (2006-2009). They were supported by five full time teaching staff, seven non-teaching staff and some part time teachers from Techiman Senior High School (TESS). In January, 2010, Sr. Christiana Chika Ifeabunike (HHCJ) took over from Sr. Veronica with Mr. George Elliot Badu Kaakyire as her assistant.
In March 2012, through the instrumentality of Hon. Alex Kyeremeh, the former MP of Techiman North, and the former Deputy Minister of Education in charge of Pre-Tertiary Education, the school was absorbed into the public-school system, and received full support from the Government of Ghana. Currently, the school has students' population of 620 and staff strength of 79 – 50 teaching staff and 29 non-teaching staff.
The School is located on the eastern part of Techiman, off the Kumasi-Techiman High way. It is about 10 kilometers from the business centre of Techiman. The school has chalked academic successes over the years by recording 100% in WASSCE since 2009 when the first batch of candidates sat for the exams. In 2013, the school was ranked first in the country and third in West Africa base on the WASSCE results.
