Screen and intervene faster with mCLASS DIBELS 8th Edition

California educators, mCLASS is one of three approved screeners in California for Reading Difficulties at K–2 for both English and Spanish.

mCLASS® DIBELS® 8th Edition is an all-in-one system for Science of Reading-based universal screening, dyslexia screening, progress monitoring, and instruction for grades K-6. Amplify’s Spanish language assessment, mCLASS Lectura, works in tandem with DIBELS 8th Edition’s English assessments. Together, these assessments help teachers understand where their Spanish-speaking students are on their path to biliteracy.

mCLASS offers teacher-administered assessment, intervention, and personalized instruction for grades K–6.

Know exactly how to monitor and support every student in your classroom, with features like:

Precise one-minute measures based on over three decades of predictive data.
Universal and dyslexia screening in one tool.
Instruction that highlights observed patterns and recommends activities.
Robust reports for teachers, specialists, administrators, and parents.

Computer-based assessments that require students to complete tasks silently or independently may over-identify students for intervention services, especially young learners who are still developing focus and attention abilities.

mCLASS requires students to actively demonstrate their proficiency in producing letter sounds, forming words, and reading texts. This approach to assessment aligns with IDA guidelines for effective screening of reading challenges. By choosing mCLASS for dyslexia screening, you’ll gain accurate information about a student’s risk for dyslexia, and gain the capability to monitor every student’s path to reading proficiency.

Validated as a universal screener and a dyslexia screener.

Strong reliability and validity evidence shows that DIBELS 8th Edition can effectively assess students in key skills linked to both dyslexia and broader reading difficulty. The research supporting DIBELS 8th Edition, conducted by the University of Oregon, is rigorous, meets high technical standards, and empowers educators to make well-informed decisions.

1. Assess skills

mCLASS DIBELS 8th Edition with dyslexia measures in Rapid Automatized Naming (RAN), Spelling, Vocabulary, and Oral Language accurately assess students’ abilities.

2. Identify risk

The DIBELS 8 composite score shows each student’s risk level, with ‘Well Below Benchmark’ indicating a need for intensive support. Students who are also ‘Well Below Benchmark’ in RAN and/or Spelling have an additional Risk Indicator icon next to their name.

3. Provide instruction

The mCLASS Instruction feature analyzes student error patterns to key dyslexia-related subtests, then recommends small groups and explicit, multi-sensory activities for reinforcing skills.

4. Progress monitor

mCLASS includes progress-monitoring measures to track student growth in letter sounds, alphabetic principle, word reading, oral reading fluency, and comprehension, so that informed instructional decisions can be made.

5. Adapt instruction

mCLASS displays indicators based on progress-monitoring performance that indicate when a change in instruction may be needed. It also updates instruction recommendations using the latest data.

Bilingual dyslexia screening

By assessing with mCLASS DIBELS 8th Edition and its Spanish counterpart, mCLASS Lectura, you’ll know with confidence whether a student truly shows signs of dyslexia or is experiencing difficulties learning a new language.

When used together, mCLASS DIBELS 8th Edition and mCLASS Lectura feature a Dual Language Report that analyzes dyslexia screening results in both languages. The report also details how each student can leverage their strengths from one language to support growth in the other.

Differentiated literacy instruction

mCLASS DIBELS 8th Edition lays the groundwork for a strong Multi-Tiered System of Supports (MTSS).

In addition to identifying students with symptoms of dyslexia, mCLASS DIBELS 8th Edition data recommends early intervention, personalized instruction, and core instruction within Amplify’s early literacy suite. Based on the Science of Reading, Amplify’s early literacy suite programs follow an explicit and systematic structure, build knowledge, and instruct on all of the foundational skills essential to literacy development.

Intervene with mCLASS Intervention and Amplify Tutoring: Staff-led Tier 2 and 3 intervention for intensive support.
Practice with Boost Reading: Personalized learning program to extend and reinforce core instruction.
Instruct with Amplify Core Knowledge Language Arts (CKLA): Core curriculum to build foundational skills and knowledge.
