The family and a BCBA will meet to discuss the child's needs and what the family hopes to get out of therapy and coaching. The BCBA will help the family identify a goal or two. Subsequently, the BCBA will design a program that will either teach a new skill or replace a challenging behaviour with another more helpful behaviour. The BCBA will train the family in the program using Behavioural Skills Training (BST). There are 4 elements to BST: instruction, modelling, role play and feedback. That is to say, the family will be confident in their ability to implement the program. The family and the BCBA will meet weekly. Parents are tasked with taking data, to monitor the child's progress. Data is a foundation of ABA. In other words, all decisions should be based on and driven by data. If you're having trouble with the amount of data that the BCBA is asking you to collect, please bring this to their attention. There are many ways to collect data and each has it's own value and place in an ABA program. The best ABA program will need changes and tweaks as it's being implemented. Likewise, ABA programs must be individualized.
