In 1974 the Sisters met for the second time and they reflected on the theme “The Role of the Religious Women in Evangelization” By then they were called AMECEA Sisters, this time they invited ARU – Association of Sisters in Uganda.
In 1980, they adopted for themselves the name «Sisters’ East Africa Study Conference» (SEASC). Through study conferences which were organized every two or three years, the aims and objectives of the SEASC became clear. These aims and objectives were articulated in the guidelines of the SEASC, later on, they became the Statutes.
The association continued to grow in Eastern and Central African English-speaking countries. In 1983, the Eritrean, Ethiopian, and Sudanese Institutes of Women Consecrated Life became members of the SEASC while retaining their national memberships in the Joint National Associations (Men and Women).
Following the 2010 secession of South Sudan from Sudan, the South Sudan Sisters Association was recognized as an independent member of ACWECA in May 2013.
Currently, ACWECA comprises Women Institutes of Consecrated Life from nine African English-speaking countries namely; Eritrea, Ethiopia, Kenya, Malawi, Sudan, South Sudan, Tanzania, Uganda, and Zambia.
In order to make it easier for the Association to conduct its service for the Church according to its constitutions in the year 2007, its executive made a request to the Congregation for Institute of Consecrated Life and Societies of Apostolic Life (CICLAS) for official recognition.
