Answer:
The BCBA did miss something.
Explanation:Children's behavior do not not elapse very easily because they are caused many factors which sometimes can be household factors.these factors contribute in a bad way in a child's life.Proper analysis helps with tackling the behavior very well and hence avoiding wrongful detection's.
The child screaming behavior has been maintained for 5 years,It is not easy to conclude that the child is back to normal for a short space of time,since the services were utilized by the family for 5 years.Alone that says a lot because the new analyst requires at-least half of the years which the ABA used to maintain the child's behavior in order to fully assess the situation.Proper maintenance requires patience and commitment in-order to achieve a desired goal, this case a written plan of a screaming behavior for consent prior for implementation.
