"All-in-one" curricula, sometimes called "school in a box", are comprehensive packages covering many subjects; usually an entire year's worth. They contain all needed books and materials, including pencils and writing paper. Most such curricula were developed for isolated families who lack access to public schools, libraries and shops.
Typically, these materials recreate the school environment in the home and are based on the same subject-area expectations as publicly run schools, allowing an easy transition into school. They are among the more expensive options, but are easy to use and require minimal preparation. The guides are usually extensive, with step-by-step instructions. These programs may include standardized tests and remote examinations to yield an accredited school diploma.
