There are a number of instructional approaches available within ABA, each of which is uniquely suited to address specific deficits in learners with Autism Spectrum Disorders. Clinicians can utilize a combination of Discrete Trial Instruction (DTT), naturalistic strategies, and rate-building procedures to maximize the acquisition, generalization, and availability of skills. Treatment integrity protocols are essential in training staff, in providing ongoing feedback to staff, and in ensuring high quality instruction for this diversity of instructional techniques.
