This church was founded by Howard Carter in the mid-1980s, and the school was started to educate the children of the church. It originally began as a high school and eventually included kindergarten and primary when there were enough children. It followed an education system known as Accelerated Christian Education (ACE), which came from the United States of America. MCA was one of the first schools in Australia to implement this system of education, closer to a homeschool academy than to the familiar type of church school.

Document 3: Adisadel College: Adisadel College, popularly known as "Adisco", is an Anglican boys school in Cape Coast, Ghana. Key aspects of the school's administration and curriculum were originally modelled on the English public school system during the colonial era. The present curriculum falls within the Senior High School system in Ghana, with overall oversight by the Ghana Education Service. The word "Adisco" is a portmanteau of "Adisadel" and "College". The school is named after what used to be a small village on the outskirts of the Cape Coast township - Adisadel Village. In recent times, the village has expanded considerably and gradually merged imperceptibly with the main township. It is now a sprawling urban suburb with vibrant commercial activities. Adisco and Adisadel Village share direct boundaries, with the former occupying the hilly landscape and part of the adjoining low-lying area. It is commonly acceptable to use the name of the village (Adisadel) in reference to the school.

Document 7: Talkback Classroom: Talkback Classroom is best known as a forum for young people to interview politicians and other leading decision makers in forums recorded for broadcast and is also known as a Voice for the Voteless on the basis of its mission to provide an opportunity for young people to take part in civic dialogue. The forum started as a classroom based project instigated by Alexandra Secondary School teacher Stephen Cutting in 1995 and provided an opportunity for secondary school students to conduct interviews (initially by telephone) with people in the news. The activity proved very popular with students and in 1996 was first heard as a segment on ABC Regional Radio Albury Wodonga via a three way 'hook up' between students in the classroom, the segment guest or interviewee and the radio program host. In 1997 the project became a monthly national forum for senior secondary school students, broadcast on ABCyouth network Triple J produced by Stephen Cutting who had taken up a secondment to ABC Radio. Talkback Classroom ran as a regular segment featuring interviews recorded by student interviewers with leading political figures in Australian politics and other decision makers until 2001 when the segment became a live forum based at the National Museum of Australia and shifted to Radio National as part of the "Life Matters" program and ABC's digital network Fly TV. From 2001 to 2008 the forum was held at the National Museum of Australia, and involved secondary school students from around Australia interviewing various prominent politicians, business and community leaders on current affairs issues. Guests included two heads of government: John Howard (Australia) and Helen Clark (New Zealand), ministers and shadow ministers and many other decision makers and opinion shapers
Document 8: Small schools movement: The small schools movement, also known as the Small Schools Initiative, in the United States of America holds that many high schools are too large and should be reorganized into smaller, autonomous schools of no more than 400 students, and optimally under 200. Many private schools of under 200 share design features which draw upon the benefits of organizations of less than 200 people. In the public school version of the Small Schools Movement, students may be given a choice of which small school they want to join. Each of the smaller schools would offer students a feeling of connectedness between students who share the same or similar interests with them. In many ways, the small schools in high schools would resemble the team system of many middle schools across the United States. Small schools allow students to have more individual attention from teachers than most average high schools. Many small schools are created by reforming a failed large school into several small ones in the same building, as is the case with the former Theodore Roosevelt High School in the Bronx in New York City.
