When it comes to ABA therapy, the duration of each session can significantly impact your child’s progress. Here's what you need to know about full-day versus half-day sessions:

  1. Full-Day ABA Therapy – Typically, full-day sessions involve 30 to 40 hours per week of therapy, spread across multiple days. This intensive approach is recommended for children with more complex needs or those requiring significant behavioral intervention. It allows for consistent learning and practice, leading to faster skill acquisition.

  2. Half-Day ABA Therapy – Half-day sessions are usually around 15 to 20 hours per week and can be a good fit for children who need less intensive therapy. These sessions are still highly effective, allowing for focused interventions without overwhelming the child.

At ABA Navigator we ultimately can provide the right session duration depending on your child’s needs, goals, and overall well-being. It’s important to work with your ABA team in the U.S. to determine the best approach for your child’s development.
