The communicative function of requesting is one of the most basic and essential forms of communication, used to express needs, desires or requests. It is especially important in the development of communication in children and people with language difficulties, such as those with special educational needs (SEN), as it allows them to interact with the environment and others to satisfy personal needs.

Types of requests:
Verbal requests:
The student uses words or phrases to express what he/she needs. For example, “I want water,” “I need help,” or “Give me the ball.”
Nonverbal requests:
Gestures, signs, or alternative communication systems such as pictograms, augmentative communication devices, or even eye-tracking are used. Example: pointing to a picture of food to ask for something to eat.
Example of use with a student with SEN:
Context: a student with Autism Spectrum Disorder (ASD) who has verbal communication difficulties is learning to use the request function through a Picture Exchange Communication System (PECS).
