About VtABA

The Vermont Association for Behavior Analysis (VtABA) is an affiliate chapter of the Association for Behavior Analysis International. VtABA aims to support professionals, families and the community by promoting an ethical, effective, individualized and research based application of behavior analytic principals. We support the growth and effectiveness of behavior analysts, other professionals and families within the state of Vermont by offering current and meaningful continuing education opportunities that are relevant to behavior analysis. VtABA hosts an annual meeting in the fall for its members to keep them up to date on the chapter's activities over the year. Board Member nominations take place after the annual meeting and elections are held online in late January.

VtABA organizes and provides an annual conference to professionals and the community by bringing nationally recognized leaders in the fields of applied behavior analysis and education to speak on topics ranging from current research to implementation of behavior analytic principles in an applied setting.

VtABA firmly believes that current research is the cornerstone of effective behavior analytic principles and thus supports and promotes behavior analytic research within the state of Vermont. Our goal is to advocate for the implementation of effective behavior analysis services across disciplines to meet the individualized needs of persons within the state of Vermont.

  • Utilize the VtABA website and social media to increase communication between members and provide resources that will benefit behavior analysts and the greater community.
  • Offer continuing education credits for BCBA’s and BCaBA’s by providing local trainings on topics relating to the field of applied behavior analysis.
  • Organize networking events for behavior analysis professionals.
  • Advocate for and ensure that certification through the Behavior Analysis Certification Board is the standard for professional behavior analysis practice in Vermont.
  • Support and advocate for an accurate representation of behavior analysis outside the field of applied behavior analysis within professional presentations, materials and media.
  • Contribute to the common goal of supporting the betterment of others through effective practice by engaging in and adhering to a respectful and effective collaborative working relationship with other professionals.

Liz Elliott MS, BCBA, LBA


I was introduced to the field of ABA in 2009 as a Behavior Interventionist at CSAC.  Watching the effects that an evidence based approach had on my students and their schools led me to become a BCBA.  The combination of social validity, cultural competency, and best practice, fortified my belief that treatment could be applied across settings.  The work I do with my clients explores the interchange between identity, community, and autonomy.  As a General Board Member, my goal is to contribute to the collective responsibility of disseminating ABA in Vermont.
