About the ELSS
What is it?
The Early Learner Skills Supplement is a supplemental skills curriculum consisting of 71 skills for early behavior intervention in autism spectrum disorders. It is designed specifically for cases that have low scores during the initial assessment; often referred to as Level 1 in many curriculums. The goals are presented systematically to be easy for the BCBA to develop skill-level appropriate programming. Targets in the ELSS are organized by both category and difficulty level to simplify the programming process.

About the Author
David Condon is the clinical director of ABA services at Success on the Spectrum – Coppell. He received his MS in Behavior Analysis from the University of North Texas in 2019, and has been working as a BCBA ever since. He has previous experience in both telehealth and in-home services. And he started at his current clinic in 2023 a little over six months after they first opened. David tends to emphasize an experimental approach beginning from the experimental analysis of behavior and then treating applied behavior analysis as a test of experimental research under real world conditions. A particular emphasis is placed on the role of attending when conditioning novel relations which can be seen throughout the book.
