This term, originally used in architecture, refers to arranging things in some form.

For example, when designing a successful garden, the gardener must adopt the concept of structure, and the seeds and plants must be arranged in a certain combination form, not only considering the different preferences of various plants for shade, sunshine and water, but also systematically considering the close relationship between them. Using this structured concept can not only give full play to the advantages of each plant, but also make up for and avoid their respective weaknesses. In this way, plants can flourish and bear countless fruits.

The concept of structure can also be applied to education, aiming at giving full play to students' strengths and making up for and avoiding their shortcomings.

Structured education is different from sensory integration therapy or auditory integration therapy, and it does not use a single technology or method. The main goal of TEACCH is to help autistic children return to society as much as possible during their growth, including helping them understand the world around them, acquiring communication skills with others, and teaching them how to make choices and decisions in their future lives.
