Literacy Assessment for Students in Grades K–12
Lexia® RAPID™ Assessment for grades K–12 helps teachers and educational leaders make decisions that promote reading success. This research-based, computer-adaptive reading and language assessment allows educators to gather predictive, norm-referenced data up to three times a year, with immediate scoring and reports.
Why Lexia RAPID Assessment?
Lexia RAPID Assessment helps measure what matters. As the need for meaningful student data continues to be a priority for schools nationwide, educators need confidence that they are measuring what matters when assessing student learning.Educators need an efficient, reliable, valid, and research-based assessment that will provide the data needed to make instructional decisions for each student.

Engaged Students

Student motivation is key when it comes to learning. RAPID's adaptive assessment design engages students at the right level during the assessment process—which connects them to the right instructional resources at the right time. This allows students to grow in their academic journey by getting the right amount of challenge for their optimal growth, thereby keeping them engaged in their own learning.
Empowered Educators

RAPID's holistic prediction of reading success is determined by a combination of performance on reading and language tasks that research indicates to be highly predictive of comprehension. This empowers educators by creating a unique reading and language profile that shows each student's strengths and weaknesses based on their performance, as well as provides classroom level data to make efficient instructional decisions. This gives educators more time to focus their instruction on what will really matter for student growth.
Improved Outcomes

RAPID specifically targets academic language skills in order to improve student outcomes. This language includes advanced and discipline-specific vocabulary, as well as sophisticated grammar and syntax. Students in all grades need to acquire and apply academic language to express complex ideas and engage deeply with texts for optimal academic growth. RAPID’s unique coverage of academic language draws attention to key elements that are rarely individually measured in reading screening assessments and allows educators to support all students in their learning journey.
Key Features
Adaptive assessment of key literacy domains
RAPID's computer-adaptive assessment allows educators to gather predictive, norm-referenced data up to three times a year within the key literacy domains of Word Recognition, Academic Language, and Reading Comprehension. Student tasks in RAPID adapt based on individual, real-time performance, which predicts students' likelihood of end-of-year success in those key domains.
View the Scope and Sequence
Screen-reading and language skills
Educators can gather data on student skill development and growth with grade-dependent tasks in the domains of Word Recognition, Academic Language, and Reading Comprehension.
Based on their performance, all students receive an individual Reading Success Probability score (RSP) that predicts their future achievement on a gold-standard, national outcome measure. Screening assessment results are provided for districts, schools, classes, and individual students.

Identify instructional needs
Designed to help schools meet the need for data-driven instruction and decision-making, RAPID determines each student's learning needs and provides educators with student groupings for teacher-led, targeted instruction after screening.

Measure skill development
Since each task is measured separately using a scale from 0 to 1,000, educators and administrators can track student progress across all RAPID tasks. This provides educators with a consistent measure of skill development based on performance throughout the year.

Data visibility and reporting
RAPID results are shared in District, School, Class, and Student Reports. Each report includes the three RAPID scores: the Reading Success Probability Score (RSP), Percentile Ranks, and Performance Scores. The RSP is an overall score indicating the likelihood of end-of-year success, while Percentile Ranks and Performance Scores describe performance on each skill. Additionally, a Lexile® score can also be reported. The myLexia.com website provides educators and administrators a dashboard with access to data, reports, training videos, and instructional materials that connect to the reading and language skills assessed in RAPID.
Mobile technology for students and educators
Lexia RAPID Assessment is available for the iPad.
