What is NET?
NET stands for Natural Environment Training and was developed by Sandberg and Partington. This type of training focuses on a child's immediate interests and activities as a guide for instruction. It is conducted in the child's typical daily environment rather than in formal teaching arrangements. Many different teaching techniques, including DTT, can be used in the NET program. Advantages of NET include optimal conditions to teach manding (verbal requests), the use of stimuli in the natural environment as target instructions (for example functional play), the reduced need to elaborate generalization procedures (since we are already using SDs from a generalized environment), the naturalistic instructional context, the ease of teaching intraverbal behavior (functional speech that is elicited by the child without the presence of a prompt), and the reduced need for aversive control.
