mCLASS DIBELS 8th Edition provides rich data that helps you make informed instructional decisions and seek out further dyslexia screening evaluation if needed:

  1. Assess skills: mCLASS DIBELS 8th Edition and optional dyslexia screenings 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.

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.

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.

Student named Marisol Mejía is shown with her English and Spanish literacy scores. English scores are mostly Well Below and Below benchmark; Spanish scores are mostly at Benchmark except for one below.

Dyslexia resources for families

Families play a crucial role in helping children overcome reading challenges. mCLASS DIBELS 8th Edition and mCLASS Lectura provide a Home Connect letter after each dyslexia screening to explain the results in family-friendly language, recommend activities, and direct families to a free website for additional at-home support.

Developmentally appropriate

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.
