Benchmark and progress monitoring assessment
mCLASS benchmark measures are consistent within a grade level to help you easily monitor growth across benchmark periods. Each assessment is also offered as a progress monitoring assessment between benchmark periods and can be conducted as often as needed.

Assessment Measure description Concept Grades

DIBELS 8th Edition

Letter naming fluency (LNF)

Students identify randomly mixed uppercase and lowercase letter names.

Knowledge of letter names

Grades K–1

DIBELS 8th Edition

Phonemic segmentation fluency (PSF)

Students identify the initial sound in an orally presented word. Students segment three- and four-phoneme words into their individual phonemes.

Phonological and phonemic awareness

Grades K–1

DIBELS 8th Edition

Nonsense word fluency (NWF)

Students make letter-sound correspondences and read pseudowords.

Alphabetic principle and basic phonics

Grades K–3

DIBELS 8th Edition

Word reading fluency (WRF)

Students read individual words aloud from a word list printed on a sheet of paper for one minute.


Grades K–3

DIBELS 8th Edition

Oral reading fluency (ORF) with retell

Students read connected text accurately and fluently and extract meaning from text.

Advanced phonics, oral reading accuracy, fluency, comprehension of text

Grades 1–6

Online reading accuracy, fluency and comprehension

Students read grade-level words and connected text silently at an adequate rate with meaning.

Word accuracy, silent reading fluency, comprehension of text

Grades 1–6

DIBELS 8th Edition

Maze Online

Students read a grade-level passage in which some words are replaced by a multiple-choice box that includes the original word and two distractors. The student reads the passage silently and applies vocabulary and word knowledge to select the word in each box that best fits the meaning of the sentence.

Comprehension of text, vocabulary

Grades 2–6



This assessment is comprised of different multiple-choice tasks to determine the student’s level of knowledge of grade-level words, whether the student has strategies for making meaning of words encountered in text, and whether the student is applying this knowledge to making meaning from text.


Grades K–3

ELM Spelling

This assessment measures the spelling grade-level words. An audio prompt of the target word is provided and the student uses letter tiles to spell the word.


Grades K–3

Rapid automatized naming (RAN)

This assessment measures how quickly students can name numeric symbols.

Rapid phonological processing abilities

Grades K–3

Comprehensive early literacy suite

mCLASS is part of the Amplify early literacy suite, which brings together curriculum, instruction, regular practice, differentiation, and assessments that measures where students are, and what is needed to promote ongoing reading success, including intervention. 


Know, don’t guess. On-demand benchmark and progress-monitoring data, including skill profiles, classroom summaries, district reporting, and analysis tools help you support each student as an individual reader, create targeted small groups, and make informed decisions. Our approach to reporting is focused on helping all stakeholders use data effectively to make decisions to advance student learning.

mCLASS with DIBELSs 8th Edition Reporting guide

Easy-to-use reports

Class summary

This report shows all students grouped by risk level, and their performance on each individual measure, along with local (district) performance percentiles.

Skill profile

This report shows a skill-based view of every student in the class, targeted instruction, and more.


View grouping recommendations, instruction suggestions, targeted lesson plans, and intervention activities for each student in every class.

Comparing populations

Compare assessment results for different student populations, such as students in different schools, grades, or demographic categories.

Comparing measures

Compares assessment results for one population of students (e.g., all students in a school, all ELL students in a district) across all or some measures associated with each mCLASS assessment.


This series of bar charts correlates results from one time period to a second time (to show effectiveness) or one measure to a second measure (to demonstrate measure correlation).

Benchmark completion

This bar chart shows the percentage of the total student population that has completed one or more assessments.

Progress monitoring fidelity

This report allows you to track progress monitoring fidelity.

Home Connect letter

Home Connect letters provide information about student results for completed measures, explain the relevance of the assessment measures in parent-friendly language, and recommend targeted activities so that students can practice related skills at home. Teachers can print these student summaries to send home and use them as a basis for discussion at parent-teacher conferences.

Instruction and intervention

mCLASS instruction provides teachers with a single view of the personalized, blended instruction (teacher-led and online) that is available to support individual student or small-group needs in skill areas directly assessed in the mCLASS assessment system. This includes:

Online student instruction and practice through Boost Reading, which places students in a personalized instruction path based on mCLASS assessment data and adapts based on progress in the curriculum. Students engage with skills-based games as well as an eReaderA game in Amplify Reading
Teacher-led instruction for whole classes, small-groups, and individual students, including activities created by Susan Hall, author of I’ve DIBEL’d, Now What. Additional instructional resources for comprehension include grade-level passages and lesson templates that provide more practice in reading comprehension.

Rigorous, teacher-led intervention with mCLASS Intervention to address students most in need of support. Check out the mCLASS Intervention page for more details.

A 10 day cycle including measure skills, group students, generate lessons, teach students, and provide practice

Boost Reading

Boost Reading provides students with targeted and engaging instruction and practice in the skill areas that students need to become successful readers, with a focus on the “Five Big Ideas” in early reading: phonological and phonemic awareness, phonics, vocabulary, comprehension, and accuracy and fluency.


Instructional resources provide grade-level passages and best-practice lesson templates for close-reading and comprehension tasks. The lesson templates cover a wide range of reading comprehension skills that can be applied with the accompanied passages for additional practice in reading for deeper comprehension.


The automatic nature of mCLASS Intervention makes targeted, staff-led, intervention a day to day possibility for busy staff. With mCLASS Intervention, what used to take educators hours—data analysis, grouping, writing targeted lessons—only takes minutes.
