Why research this topic?

Procedures to teach specific skills for individuals with autism Many autistic learners experience difficulty acquiring new skills, maintaining them over time, and generalizing acquired skills to novel circumstances. Individuals often exhibit disfluent responses that lack speed and fluidity. Proponents of precision teaching (PT) and fluency building (FB) have questioned whether this problem is a result of the teaching techniques used with autistic students and have proposed that PT and FB support the acquisition, retention, and generalization of skills. It is worthwhile to examine the literature to ascertain if PT and FB are evidenced-based teaching protocols for teaching autistic learners.

Precision teaching is an instructional method based on the direct measurement of observable and repeatable behavior done daily. It measures learning as a change in response rate, relying on the visual analysis of recorded performance data on the Standard Celeration Chart (SCC), which provides a graph of fluency of behavior that can be visually analyzed to assess the effectiveness of teaching. Changes and modifications to instruction are made based on collected data. Precision teaching has been used with individuals with ASD to teach motor skills (Fabrizio et al., 2007), answering questions (Zambolin et al., 2004), and storytelling (Schirmer et al., 2007).

Fluency training, which is based on the principles of ABA, involves teaching until the student meets a two-part mastery criterion of a predetermined accuracy criterion of percent correct (accuracy goal) at an optimal rate of accurate responses (the fluency criteria). Binder (1996) defined fluency as the combination of response accuracy and response rate that demonstrates competent performance. Fluent behavior is accurate and fast. Research highlights four outcomes of fluency training: retention, endurance, stability, and application (RESA) (Binder, 1996). Retention refers to the ability to maintain high levels of responding after a period of time without practicing the target skill. Endurance is the capacity to maintain high rates of responding over longer time blocks than were used in training. Persistence of high rates of responding in the face of distraction, in different settings, or with different people indicates that behavior is stable. Application is defined as the ability to perform a skill at fluent rates with novel materials and instruction and in more complex contexts. Application is also seen in the emergence of an untrained composite skill when the relevant component skills have been trained to fluency (Binder, 1996).

PT and FB have long histories in educational research, yet their application with autistic children has not been systematically evaluated. The authors sought to determine whether these methods are effective, what kinds of skills have been taught with them, and whether they lead to fluency outcomes beyond acquisition.

The authors asked three central questions:

1. 1. What types of skills have been targeted using PT and FB with autistic children?
  2. What study designs and quality indicators characterize this literature?
  3. What are the reported outcomes—especially in terms of fluency (retention, endurance, stability, application)?

What did the researchers do?

The authors systematically reviewed research on precision teaching (PT) and broader fluency-building (FB) methods used to teach children diagnosed with autism. An initial search of studies published between 2007 and 2018 yielded 147 possible articles for review. Thirteen studies met the inclusion criteria of being published in an English-language peer-reviewed journal, having participants under 18 with autism spectrum disorders, and examining interventions that used PT or FB. Studies that failed to publish measurable outcomes were excluded. Twelve of the included thirteen studies were published from 2010 onward, indicating recent interest in PT and FB.

All studies used single-case research designs (SSRDs which included multiple-baseline (across participants/stimulus sets/behaviors), AB (pre/post-test), or alternating-treatments. No studies were found that used randomized control trials. The most frequently targeted skills were reading/phonics (5 studies), intraverbals (2), and tacts (2). Other targets included writing, imitative movements, vocational/assembly skills, and noun labels. Three studies compared FT/FB to discrete trial instruction. Two used computer-assisted FB packages. One study evaluated AIMSweb®, a reading-fluency program.

The authors applied several quality frameworks (Reichow et al., ROBINS-I, AMSTAR-2) to assess rigor and bias, providing a structured way to interpret the overall strength of evidence. The Reichow et al. (2008) framework evaluates empirical validity and quality of autism interventions. The ROBINS-I was used to assess the risk of bias. Overall review confidence was examined using the AMSTAR-2. The PND (Percentage of Non-overlapping Data) evaluated effect size when reported in the studies.

What did the researchers find?

All 13 studies reported positive skill gains for targeted behaviors across academic (reading, phonics, writing) and language (tacts, intraverbals) domains. The evidence from the literature base that PT and FT produce retention, endurance, and stability, and application exists, but is uneven because only a few of the studies tested all RESA components.

Intervention format varied across the studies. Of the 35 children, aged three to fifteen, who participated in the study, 9 children took part in research on PT, in which their performance was charted on the standard celeration chart. Twenty-six children participated in fluency-building/fluency-training studies. Intervention dosage, the duration of time taught with PT and FB, varied widely, from minutes (e.g., ~11 min to reach aims) to weeks or months (e.g., 22–43 weeks; up to 14 months).

The Reichow et. al. (2008) assessment tool was used to evaluate the empirical validity and quality of the 13 studies. Six studies were classified as having “strong” methodological quality. These included one PT study (Cihon et al., 2017) and four FB studies (Holding et al., 2011; Nopprapun & Holloway, 2014; O’Brien et al., 2018; Grindle et al., 2013). The remaining 7 studies were rated as “adequate”.

The authors noted limitations in the current research base. The current evidence base is small and heterogeneous. Only a modest number of studies met criteria, spanning diverse targets (academics, communication, etc.), settings, and procedural fidelity. That heterogeneity precludes meta-analysis and limits generalizability. Some studies had insufficient data points for effect sizes. Not all studies assessed fluency outcomes, and outcome-measure reliability was seldom reported. No studies have been performed with randomized control trials. Most studies did not report fidelity or interobserver agreement.

What are the strengths and limitations of the study?

Martinho et. al. (2022) was published in the International Journal of Educational Research, and the authors are associated with Queen’s College in Belfast, Ireland. This examination of the research base for precision teaching and fluency-building was well conducted. It utilized the PRISMA (2010) process to conduct the search, covered a broad age range, and used quality indicators as a reporting measure. A major strength of this analysis is that it elevates fluency as a criterion outcome. By foregrounding rate (not just accuracy), Martinho et al. (2022) highlight outcomes educators care about, skill maintenance under distraction, quick recall, and transfer to other materials and settings. This pushes autism education research toward performance robustness rather than one-off mastery checks. The use of the Reichow et al. assessment, a field-standard tool for research quality appraisal, adds a level of rigor in the evaluations of the included studies, giving readers an interpretable “weight of evidence” rather than a simple narrative tally. In terms of conceptual clarity, Martinho, et al. distinguish PT as a whole system (goal setting, timed practice, SCC decision-making) from FB procedures that can be used with or without full PT, preventing a common conflation in the literature. Limitations worth noting pertain more to the state of the current research base than to the methodology of this study. Martinho and colleagues intended to review the literature on precision teaching with children, which they successfully did. However, it would be beneficial to employ their methods to examine precision teaching research conducted with adults.

What do the results mean?

PT and fluency-building methods show consistently positive, and in several cases large, single-case effects for children with autism, especially in early academic and verbal domains. However, the current literature is small and often does not fully test the hallmark fluency outcomes. More rigorous research is needed to firmly establish them as evidence-based practices. Priorities for future research should include larger and more rigorous SSRDs and, where feasible, studies with randomized control trials. The evidence for PT and FB would benefit from a standardized fluency-outcome measurement, as well as consistent effect-size reporting. Further replication across skills and settings is also warranted.

The findings support the potential efficacy of PT and FB approaches for enhancing educational outcomes in children with autism. However, as Martinho and colleagues discussed, due to the limited number of high-quality studies, further research is needed to:

1. 1. Strengthen the empirical research foundation.
  2. Confirm and generalize these promising effects across diverse contexts and populations.
  3. Standardize PT implementation. Future studies should clearly specify aim setting, timing parameters, decision rules, and SCC usage, so PT can be distinguished from general timed practice.
  4. Broaden outcomes and timelines. Include maintenance probes (4–12+ weeks), generalization to natural settings, and socially valid outcomes (classroom participation, independent work).
  5. Compare components. Use dismantling or additive designs to test PT as a system (with SCC-guided decisions) versus FB alone, clarifying where the incremental benefit lies.
  6. Report implementation fidelity data. Routine fidelity checks for timing, charting, and decision frequency would improve interpretability and replication.

The authors recommended some practical takeaways for educators/BCBAs when using precision teaching and fluency-building protocols. If you already run skills practice, don’t rely on accuracy alone: measure frequency and chart celeration to make instructionally precise decisions. Set fluency aims linked to real-world performance (e.g., reading words/minute that supports comprehension) and evaluate RESA outcomes explicitly. It is important to document decision rules (when to change materials, timings, aims) to make the PT process auditable and replicable. Finally, plan probes for generalization/maintenance.
