I feel that the trainer is not recognized by the state, and the authority of the license issuing agency is also denied by Ministry of Human Resources and Social Security. At present, "sensory trainer" has not been recognized as a profession, and there is no national unified certification examination and qualification certificate. No matter what kind of occupation, only the certificates issued by Ministry of Human Resources and Social Security and the vocational skill appraisal administrations of various provinces (municipalities and autonomous regions) are authoritative, and the certificates of various associations cannot be used as qualification certificates, and the qualification certificates of sensory trainers are not recognized by the public. At present, the profession of sensory perception teachers in China has not been certified by the relevant state departments, and there is no corresponding professional certification examination in China. The current situation is that one institution or several institutions jointly carry out fee-based training, ranging from three to five days to half a month, basically giving money to certificates! This kind of training can be called specialty. In foreign countries, only occupational therapists can engage in sensory training, which belongs to the medical field. Can four years' study in college be the same as a few days' training? Parents should also be reminded that sensory training conducted by non-professionals is harmful to children because there is no systematic research. The key of sensory integration training is to give children a variety of stimuli such as vestibule, muscle, joint, skin touch, vision, hearing and smell at the same time, and combine these stimuli with exercise.

Sensory integration training involves the relationship among psychology, brain and body, and is not only a physiological function training. In the process of training, children gain a sense of proficiency, enhance their self-confidence and self-control, feel their control over the body under guidance, change from the original anxiety to pleasure, and dare to challenge their will and imagination on the basis of actively accumulating experience.

Sensory integration training is to cultivate children's interest and build their self-confidence with patience; Spontaneity is effective to make children feel happy in the game; Sensory integration training varies from person to person, so that children have all kinds of sensory stimuli every day.

Since the establishment of the first guild hall in Linyi in 2009, after just over eight years' operation, Else Gantong has developed into a large-scale education and training company. Different from the hard indicators of cultural subjects, the Gantong training industry is the outlet and the market development prospect is good. "From the expansion speed of' opening one family a month', we can know that the demand in the industry is huge, which stems from parents paying more and more attention to the cultivation of children's basic abilities.
