This comparison draws in part from “Online Mentorship in Precision Teaching w/ Kerri Milyko (BACB, BCBA, RBT)” (The Daily BA), and extends it with peer-reviewed research from our library of 27,900+ ABA research articles. The decision framework, BACB ethics code references, and cross-links below are synthesized by Behaviorist Book Club.
View the original presentation →The dominant approach to skill acquisition programming in ABA practice uses accuracy criteria — typically 80% or 90% correct across a specified number of sessions — as the mastery standard. Precision Teaching adds rate to this picture, targeting a specific frequency of accurate responding per unit of time. The distinction matters clinically: accuracy criteria tell the practitioner that the learner can perform the skill; rate criteria tell them whether the learner can perform it fluently enough for real-world use. This comparison examines the two approaches across dimensions most relevant to ABA practitioners making programming decisions.
| Factor | Evidence-Based Approach | Traditional Approach |
|---|---|---|
| Mastery Standard | Accuracy-Based: Mastery defined as X% correct across Y sessions. No rate specification. A learner performing 1 correct trial per minute and one performing 30 per minute may both meet criteria. | Rate-Based (PT): Mastery defined as X correct responses per minute at Y% accuracy. Rate specification reflects the performance level needed for ecological functionality. |
| Generalization | Accuracy-Based: Skills acquired to accuracy criteria may not generalize spontaneously, particularly in novel or distracting environments where slower responding fails. | Rate-Based (PT): Fluently acquired skills generalize more readily across settings and conditions. High rate performance frees cognitive resources for context adaptation. |
| Maintenance | Accuracy-Based: Maintenance is not explicitly targeted. Skills may require ongoing practice to maintain accuracy, with no systematic retention monitoring. | Rate-Based (PT): Fluency targets predict stronger maintenance. PT protocols include retention probing to verify durable learning and identify when re-teaching is needed. |
| Instructional Decision Speed | Accuracy-Based: Standard graphing on linear scales requires multiple sessions before trends are clearly visible. Instructional changes may lag 1-2 weeks behind the data. | Rate-Based (PT): Daily probes on the SCC produce visible celeration trends within 3-5 days. Instructional modifications can be made within the first week of program implementation. |
| Ecological Validity | Accuracy-Based: Accuracy criteria do not directly reflect real-world performance demands, which typically require both correct and timely responding in natural contexts. | Rate-Based (PT): Rate targets are derived from naturally occurring performance rates in the ecological context, producing objectives aligned with functional skill use. |
| Implementation Demand | Accuracy-Based: Standard percent correct data collection is familiar and low-burden. Requires no additional training in charting or rate calculation. | Rate-Based (PT): Daily probe data collection, SCC charting, and celeration calculation require training and system modification. Higher implementation demand with significant clinical return. |

Use this framework when approaching online mentorship in precision teaching w/ kerri milyko (bacb, bcba, rbt) in your practice:
Does the data support a need for intervention? Is there a meaningful impact on the individual's quality of life, safety, or access to reinforcement?
YES → Proceed to assessment NO → Document reasoning, monitor
A functional assessment should guide intervention selection. Avoid defaulting to standard protocols without individual analysis. Consider environmental variables, setting events, and private events.
YES → Select evidence-based approach matched to function NO → Complete assessment first
Goals should be co-developed. Assent and informed consent are ethical requirements. The individual's preferences and values matter in selecting both goals and methods.
YES → Proceed with collaborative plan NO → Engage in shared decision-making
This course covers the clinical and ethical dimensions in detail with structured learning objectives and CEU credit.
