Over 50 years ago, with the arrival of a large expatriate community in Monrovia, Liberia a need arose to provide an American education for expatriate children in Liberia. Thus the American Cooperative School, ACS came into being, starting out with just a handful of students, ACS evolved into a school of over 400+ students and was known as one of the top American-International schools in West Africa. As the school grew so did the diversity of the students attending, at one point the school hosted students from over 40 countries. Many of the families at ACS worked for multinational companies, were members of various diplomatic communities, and local Liberians.
* Due to the Liberian Civil War the school closed in 1989.
After several years of peace and a strong desire to reopen the school from the ACS alumni, local Liberians, and with the unwavering support of the American Ambassador Booth, The American International School of Monrovia (AISM) opened its doors on October 8, 2007, to a new school and a fresh start. The opening of AISM was a strong signal to international organizations, companies, nonprofits, and diplomatic communities that Liberia could once again be a family post. Moreover, more Liberian families began returning home to AISM. Former Liberian President Ellen Johnson Sirleaf was instrumental in opening AISM and continues to be an advocate of the school.
AISM is an independent, non-profit, co-educational day school located in Congotown, a suburb of Monrovia. AISM is licensed to operate by the Liberian Ministry of Education and accredited by the Middle States Association of Colleges and Schools (MSA).
Our school has a solid community and a rich historical foundation that works together to support one another.
