Unlabelled: Geographic distribution patterns of board certified behavior analysts may be useful in analyzing the growth of the field. First, we present an international snapshot of Behavior Analyst Certification Board (BACB) certificants, then analyze relative growth rates between countries from 1999 to 2019. This is followed by an in depth review of certificant distribution patterns in the United States and Canada, as well as the ratios of experienced behavior analysts to new certificants.

ABA may be uniquely positioned to have broader impacts with culturally and linguistically diverse (CLD) client populations, not only due to its growth and increased social acceptability, but also because a segment of the field practices within the education system. Decades of misinformation have potentially reduced the widespread reliance on learning pedagogies derived from behavior analytic research. Disseminating ABA technologies depends on an advocacy-based approach to close gaps from research-to-practice.

Such data often are interpreted only with visual analysis. However, a growing movement in the field is to quantify results to improve decision-making and communication across studies and sciences.

In the 1950s and 1960s, McConnell's planarian laboratory posited that conditioned behavior could transfer after regeneration, and through cannibalization of trained planaria. These studies, the responses, and replications have been collectively referred to as the "planarian controversy.

The goal was to develop a measure of level change for single case experimental research that met several practical requirements: (a) the measure is adaptable to designs with varying numbers of observations per, and across, phases; (b) the measure is adaptable to situations in which slope does and does not exist; (c) the measure has no ceiling, as is the limitation with commonly used overlap-based measures of effect size; and (d) the measure is computationally transparent and easily computed using widely available analysis tools (e.g.

The individuals served by behavior analysts are often funded by Medicaid, insurance companies, or private pay. The first two options usually require progress notes detailing graphically and quantitatively the behavioral outcomes. These progress notes usually come in the form of a written account of milestones achieved or barriers faced, graphical displays of behavioral data, and summary tables.
