Enhancing special educators' data literacy is critical to informing instructional decision-making, especially for students with learning disabilities. One tool special educators commonly use is curriculum-based measurement (CBM). These data are displayed on time-series graphs, and student responsiveness is evaluated. Graph construction varies and…

Progress monitoring data are central to making informed decisions on intervention intensification for struggling learners. The general outcome measure (GOM) of curriculum-based measurement of oral reading fluency (CBM-R) has been found to correlate with high-stakes assessment; however, data are highly variable, resulting in decisions that must be…

The current availability of research examining the precision of single-skill mathematics (SSM) curriculum-based measurements (CBMs) for progress monitoring is limited. Given the observed variance in administration conditions across current practice and research use, we examined potential differences between student responding and precision of…

Replication studies in special education are necessary to strengthen the foundation upon which instruction and intervention for students with disabilities are built. J. Jenkins et al. (2017) found intermittent reading fluency progress monitoring schedules did not delay decision-making and were similar in decision-making accuracy to the traditional…

A growing body of research suggests that growth in early literacy skills, including letter sound fluency, is predictive of later reading outcomes. In turn, educators and school psychologists use measures of letter sound fluency to monitor student response to early reading instruction. Limited research has evaluated whether decision-making…

Effective inclusion of English Learners (ELs) in multi-tiered systems of support (MTSS) is necessary for this growing subset of students to access the intended outcomes of MTSS, specifically improved academic outcomes. Facilitating MTSS systems that are appropriately responsive to the heterogeneous needs of ELs may be particularly challenging. In…

The current study evaluated whether goal-setting practices that account for seasonal developmental patterns of reading growth decreased the number of weeks data needed to be collected in order to yield accurate response to intervention decisions for a sample of 224 third-grade students. The extent to which more complex decision-making practices…

Difficulties in writing can emerge as early as preschool, and often coincide with developing difficulties in reading (Berninger et al., 1997; Graham & Santangelo, 2014; Graham et al., 2020), as reading and writing are fundamentally connected skills (e.g., Fitzgerald & Shanahan, 2000). Writing instruction in general has had positive effects…

The transition from sounding out unfamiliar words to effortlessly reading connected text does not occur all at once nor at the same rate for students. The purpose of this study was to explore the accuracy of three decision rules (data point, median, and trend line) applied to progress monitoring outcomes of alphabetic principle (nonsense word…

The transition from sounding out unfamiliar words to effortlessly reading connected text does not occur all at once or at the same rate for students. The purpose of this study was to explore the accuracy of three decision rules (data point, median, and trend line) applied to progress monitoring outcomes of alphabetic principle (nonsense word…

Despite repeated findings that within-year growth in oral reading rate is nonlinear for many students, existing decision-making frameworks to evaluate response to intervention assume that growth is linear across an entire school year. The purpose of this study was to evaluate the consequences of failing to account for nonlinear growth among…

Teachers have difficulty using data from Curriculum-based Measurement (CBM) progress graphs of students with learning difficulties for instructional decision-making. As a first step in unraveling those difficulties, we studied teachers' comprehension of CBM graphs. Using think-aloud methodology, we examined 23 teachers' ability to…

Using data to inform instructional decisions is a pillar of special education practice. Curriculum-based measurement (CBM) is a systematic, ongoing assessment framework that allows special educators to monitor the progress of their students to determine the need for instructional adaptations. CBM and data-based instructional decision-making have a…

The purpose of this review was to synthesize research on the effect of professional development (PD) targeting data-based decision-making processes on teachers' knowledge, skills, and self-efficacy related to curriculum-based measurement (CBM) and data-based decision-making (DBDM). To be eligible for this review, studies had to: (1) be published…

School psychologists regularly use decision rules to interpret student response to intervention in reading. Recent research suggests that the accuracy of those decision rules depends on the duration of progress monitoring, the number of observations available, and the amount of measurement error present. In this study, we extended existing…
