After 20 years as a nun, Christiana Thorpe left convent life to devote herself to the protection and education of girls and returned to Sierra Leone. She became a teacher and later the principal of St. Joseph's Secondary School for girls in
Makeni, a village north of the capital city of
Freetown. In 1993, Christiana Thorpe became the only woman in a 19-member cabinet under the military-led government under
Captain Valentine Strasser, serving as Deputy Minister of Education and later Minister of Education. She formed and chaired the Sierra Leone branch of the
Forum for African Women Educationalists (FAWE-SL) in 1995, focused on ensuring girls' access to quality education, especially those affected by the war in Sierra Leone. FAWE-SL established schools, offered trauma counselling for war-affected girls, and promoted women's conflict resolution skills. Thorpe was appointed as the Chief Electoral Commissioner and Chairperson of the National Electoral Commission (NEC) by
Ahmad Tejan Kabbah,
President of Sierra Leone, in 2005. Thorpe improved elections by introducing a biometric system, training staff, and updating voter lists to prevent cheating and increase trust. After the end of her second term, in 2016, she was appointed one of two Deputy Ministers of Education, Science and Technology in a cabinet reshuffle, though one source states that parliamentary approval was still pending as of April. ==Honours==
