Algebra is critical to high school graduation and college success, but student achievement in algebra frequently falls significantly below expected proficiency levels. While existing research emphasizes the importance of quality algebra instruction, there is little research about how to conduct problem analysis for struggling secondary students.…

Given that most schools already conduct reading screening multiple times per year, often using multiple measures, it makes sense to revisit why all this screening may not be giving schools the desired return on investment that they are after. The purpose of this article is to equip school psychologists with an understanding of four common dyslexia…

This article is the second of a series of articles appearing in "Communiqué" about how school psychologists can adopt and promote the evidence-based practices in math assessment and instruction. The focus of this article is on measuring math skills for screening, diagnostic decisions, and progress monitoring. [For the first article in…

The current study examined the effectiveness of Incremental Rehearsal (IR) for teaching Chinese character recognition using a single-case experimental design. In addition, a morphological component was added to standard IR procedures (IRM) to take into account the role of morphological awareness in Chinese reading. Three kindergarten students in…

This innovative guide is now in a revised and expanded second edition with an even stronger applied focus. It helps educators harness the potential of single-case design (SCD) as a critical element of data-based decision making in a multi-tiered system of support (MTSS). The authors present simple and complex SCDs and demonstrate their use to…

The Ability Achievement Discrepancy model remains the primary identification method used by school personnel. This study examined identification of a specific learning disability using the Ability Achievement Discrepancy model with the Woodcock-Johnson IV (WJ-IV). Two different test scores can be used to represent the ability construct: one that…

Screening is necessary to detect risk and prevent reading failure. Yet the amount of screening that commonly occurs in U.S. schools may undermine its value, creating more error in decision making and lost instructional opportunity. This 2-year longitudinal study examined the decision accuracy associated with collecting concurrent reading screening…

A skill-by-treatment interaction (STI) isolates skill deficits and manipulates conditions to match them to student needs. Based on the learning hierarchy, preintervention scores can help predict which intervention will be most successful for an individual student. This study compared the efficacy of a modeling and practice-based decoding…

Universal screening is useful in the early identification of behavioral and emotional concerns, but teacher-related variance can potentially influence screening scores and resulting decisions. The current study examined the extent to which burnout and self-efficacy as teacher-level variables accounted for variance in universal screening scores.…

The amount of information that students can successfully learn and recall at least 1 day later is called an acquisition rate (AR) and is unique to the individual student. The current study extended previous drill rehearsal research with word recognition by (a) using students identified with a learning disability in reading, (b) assessing set sizes…

Bronfenbrenner (1977) defined ecological-systems theory (EST) as the study of the multiple interconnected environmental systems that influence individual development. To understand the child, psychologists must fully examine the environment in which the child lives including the home, school, community, and culture (Bronfenbrenner, 1986). There…

Many school psychologists spend a large portion of their time conducting evaluations for special education, but school psychologists' confidence in learning disability (learning disability[ies] [LD]) identification has not been examined experimentally. This study examined differences in 376 school psychologists' confidence in their identification…

This study examined the extent to which cognitive ability index scores predicted multidisciplinary teams' (MDT) SLD identification within a response-to-intervention (RtI) method after accounting for RtI slope and norm-referenced achievement scores. Results showed that four achievement composite scores (i.e., basic reading, reading comprehension,…

Students with specific learning disabilities (SLDs) represent a large proportion of those receiving special education services in U.S. schools, but the relationship between student-level variables and SLD identification is still not well understood. The purpose of this study was to examine the extent to which data collected as part of a…

Learning disability (LD) identification has long been controversial and has undergone substantive reform. This study examined the consistency of school psychologists' LD identification decisions across three identification methods and across student evaluation data conclusiveness levels. Data were collected from 376 practicing school psychologists…
