Lexia Learning Introduces Lexia RAPID Assessment

Lexia Learning has launched RAPID (Reading Assessment for Prescriptive Instructional Data) Assessment, a computer-adaptive screener and diagnostic tool for students in grades 3–12.

Designed for administration in the fall, winter, and spring, RAPID uses a computer-adaptive process to identify and monitor reading and language skills so that teachers can quickly acquire actionable data for instruction and measure the long-term growth of each student’s skills. In addition to measuring the skills that are highly predictive of reading success –– word recognition, vocabulary knowledge, syntactic knowledge, and reading comprehension—RAPID helps educators make decisions within a Response to Intervention or Multi-Tier System of Support model by helping to determine which students are at-risk for difficulty and then providing guidance on the level of instructional intensity needed for student success. RAPID also provides a diagnostic profile for each student, pinpointing specific academic areas that should be targeted. Additionally, the diagnostic profile links directly to Lexia-provided instructional strategies for the teacher and identifies students with similar profiles for small-group instruction.

This new assessment is the result of Lexia’s ongoing partnership with researchers from the Florida Center for Reading Research (FCRR), a multidisciplinary research center at Florida State University. FCRR’s continuing research and innovation in the area of language and literacy assessment was instrumental in determining the most predictive skills, testing methodologies, and strategies to convey meaningful data in a manner that best informs instruction.

Rather than administer several lengthy assessments, teachers and administrators using RAPID obtain the information they need regarding student progress via a Reading Success Probability (RSP) score, a set of Ability Scores, and a set of Percentile Scores based on the student’s grade level. All three scores are provided at the student level and then aggregated to the class, grade, school, and district levels.

Each student receives an individual RSP score indicating the overall level of instructional intensity needed to reach grade level proficiency by the end of the school year. The RSP score then becomes a roadmap for educators with a prediction of students’ future reading success on a standardized outcome measure. The Ability Score represents an estimate of each student’s abilities and development in a particular skill area within and across grade levels (for example, their current level of vocabulary knowledge). This score, when compared to a student’s prior Ability Scores, indicates relative growth in the skill. The Percentile Score shows a student’s relative performance compared to grade-level norms and guides instructional strategies based on the student’s personal profile of strengths and weaknesses.

These three types of information provide educators with an enormous amount of insight when determining what steps need to be taken to drive student gains, the announcement states. Teachers and administrators can see how many students have a high probability of success (an RSP of 70 percent or greater) and the distribution of RSP scores across a grade, school, or district. Educators can also longitudinally track students’ personal skill development growth over a school year and across multiple years. Additionally, the data enables educators to track the impact of instructional interventions and programs across a school or district and administrators can use the school- and district-wide profiles to assess the need for curriculum review.
