CBM Assessment Materials
Spelling-CBM and Written Expression CBM Assessment Materials
Research-validated tools for universal screening and progress monitoring in spelling and written expression within an MTSS framework.
About These Materials
Reliable, Valid CBM Tools for Spelling and Written Expression
Spelling Curriculum-Based Measurement (S-CBM) and Written Expression CBM (WE-CBM) are brief, standardized assessments that provide reliable and valid data for making important educational decisions.
Developed by Dr. Mark R. Shinn and grounded in decades of CBM research, these materials support schools in identifying students who need additional support and monitoring their progress over time.
Whether used for universal screening three times per year or frequent progress monitoring within a tiered support system, these tools give educators the data they need to act quickly and confidently.
Why These Tools Work
What Makes These Tools Different
Research-Validated
Developed from an extensive body of CBM research spanning four decades, ensuring reliability and validity for high-stakes educational decisions.
MTSS-Ready
Designed for seamless integration into Multi-Tiered Systems of Support — from Tier 1 universal screening to Tier 3 intensive progress monitoring.
CLS and WSC Scoring
Supports both Correct Letter Sequences (CLS) and Words Spelled Correctly (WSC) scoring, providing richer diagnostic data than traditional methods.
Grades 1–8 Coverage
Comprehensive grade-level materials spanning Grades 1 through 8, ensuring appropriate assessment tools are available across the elementary and middle school years.
Easy to Administer
Brief, standardized administration procedures that classroom teachers and specialists can implement with minimal training and disruption to instruction.
Science of Reading Aligned
Grounded in the Science of Reading and systematic phonics principles, ensuring assessments reflect current best practices in literacy instruction.
Applications
Four Ways Schools Put These Tools to Work
Universal Screening
Administer three times per year to identify students at risk for spelling and written expression difficulties before they fall significantly behind.
Progress Monitoring
Use frequently with students receiving intervention to determine whether their rate of improvement is sufficient to close the gap with grade-level peers.
Data-Based Decision Making
Generate reliable data to support special education eligibility decisions, intervention planning, and program evaluation at the school and district level.
RTI and MTSS Implementation
Provide the assessment backbone for Response to Intervention and MTSS frameworks, ensuring all tiers of support are driven by objective, actionable data.
