Get struggling K–6 readers on track with our reading intervention program.
mCLASS® Intervention is a staff-led reading intervention that does the heavy lifting of data analysis and lesson sequencing, freeing up teachers to teach the reading skills each student needs.
About mCLASS Intervention
Getting ¼â½ÐÊÓÆµapp caught up on reading skills requires more than just “extra help” in small groups. It requires teaching that directly targets the specific skills each group needs to learn next. How does mCLASS Intervention help? It does the heavy lifting of data analysis and lesson generation.

Research-based, classroom-tested
K–2 ¼â½ÐÊÓÆµapp in mCLASS® Intervention grew by up to 8 student growth percentile points more in early literacy skills than similar peers not enrolled in mCLASS Intervention, according to a study by the Institute of Education Sciences (IES).
Our approach
mCLASS® Intervention follows a research-based skills progression and uses software to analyze results, form small groups, build engaging lessons for each group, and update skill profiles and groups every 10 days.
Measure skills
Every 10 days, educators progress-monitor ¼â½ÐÊÓÆµapp on the skills they’re working to build. mCLASS Intervention analyzes these results, updates ¼â½ÐÊÓÆµapp’ placement on the learning progression, and identifies what they should focus on next.


Group ¼â½ÐÊÓÆµapp
Once each student’s profile is updated, mCLASS® Intervention analyzes the results of other ¼â½ÐÊÓÆµapp and arranges ¼â½ÐÊÓÆµapp by skill into small groups of 4–6.
Generate lessons
Once groups are formed, mCLASS® Intervention determines the ideal focus for each group and automatically prepares two weeks of targeted lessons. See a sample here.


Teach ¼â½ÐÊÓÆµapp
Staff then deliver the lessons to the small group of ¼â½ÐÊÓÆµapp—either with the interventionist coming into the room or the ¼â½ÐÊÓÆµapp going to a different room.
What’s included
mCLASS Intervention covers the five big ideas of reading: phonological awareness, phonics, fluency, vocabulary, and comprehension. The program comes with a mix of print and digital components to help you serve ¼â½ÐÊÓÆµapp.
Targeted lesson plans
mCLASS Intervention provides a bank of more than 4,000 research-backed activities, including multisensory activities that use auditory, visual, tactile, and kinesthetic techniques.
Lesson builder
The lesson builder automatically assembles activities into detailed lessons that target the skills each group is ready to learn.

Easy-to-use lesson materials
mCLASS Intervention provides both print kit materials and a digital card app to help you streamline lesson preparation.
Practice app
The practice app allows ¼â½ÐÊÓÆµapp to continue to improve their automaticity in decoding with engaging games.

Progress monitoring
Standardized diagnostic probes allow educators to closely monitor progress.
Educator and administrator reports
Analytical reporting allows educators to see each student’s progress throughout the year.


Training resources
Embedded training modules and a pedagogical help desk get you started and maximize your ¼â½ÐÊÓÆµapp’ success.
