ABA has documented effectiveness for learners with autism. Over the past 15 years, the effectiveness of early intensive behavioral intervention has been empirically validated. Many of these ABA programs have utilized an impressive array of ABA technology, while some programs have relied heavily on the use of discrete trial instruction. Recently, the model of Natural Environment Training has been discussed as an important expansion of these programs. In addition, the utility of Fluency Based Instruction for learners with autism has been highlighted. These two ABA approaches have much to offer students with autism. Their inclusion in educational programming may enhance the effectiveness of instructional efforts. **********
