This is a formal style of home education, sometimes called “school-at-home”, where the parents teach the child using curricula and/or timetables they have either bought/obtained or devised themselves. Many families feel more comfortable using a structured approach, some find that this naturally suits their child’s individual learning style. Other families move between structured and unstructured methods depending on what suits their/their children’s circumstances at the time. Off-the-shelf curriculums can be purchased. Many American companies provide quite formal multi-subject curricula (some of these follow established educational philosophies such as Classical Education, Charlotte Mason or follow a particular belief system). There are also a small number of British curriculum providers which tend to focus on meeting the national curriculum (although home educators are not obliged to follow the national curriculum).
