The early history of CBMIn the mid-1970s, late American educational psychologist and director of the Special Education Program at the University of Minnesota, Stanley Lynn “Stan” Deno, began his research on what would become known as curriculum-based measurement.Teachers at that time didn’t have many fair or accurate methods to formatively assess students. In the journal ISRN Education, Gerald Tindal writes:
Basal series had mastery tests with little technical adequacy (reliability and validity) in decision making and actually misinformed teachers about skills being learned and practiced by students. Informal reading inventories and readability-based estimates of passage difficulty were not (and are still not) reliable.Hence Deno’s interest in -- and need for -- a new and improved method of measurement. His initial decade’s worth of work focused primarily on the three areas of language arts (i.e., reading, writing, and spelling).Long-term, Deno’s data-based program modification manual helped establish measurement systems that:
- Were easy to construct
- Were quick to administer and score
- Usable by all
- Had technical adequacy
- Allowed time series data to be collected on student programs

What is curriculum-based measurement?[caption id="attachment_3459" align="aligncenter" width="600"] Credit: Enokson[/caption] Remember having to write tests every two or three weeks at the end of a math, science, social studies, reading, insert-school-subject-here unit?At the end of the term or year, you’d get a report card listing all your averaged scores.A summative assessment is fantastic for emphasizing the product of student learning. But it falls short in regard knowing the process of student learning.Enter CBM.
In short, curriculum-based measurement is a powerful assessment tool teachers can use to both test and measure student progress.Jim Wright, a certified school psychologist and school administrator in central New York State, created Curriculum-Based Measurement: A Manual for Teachers. And in it, he defines CBM as:
NCME may be still getting its feet wet in the classroom, but Curriculum-Based Measurement has a 30-year history of research on supporting instruction w/ measurement.

A method of monitoring student educational progress through direct assessment of academic skills. CBM can be used to measure basic skills in reading, mathematics, spelling, and written expression. It can also be used to monitor readiness skills.What’s more, curriculum-based measurement is an excellent way for teachers to gauge the effectiveness of their own instructional methods.
How does CBM work?Teachers who implement CBM will briefly test students, usually once or twice a week, based on academic content from their school curriculum.These tests, or “probes,” are intended to be brief and last anywhere from one to five minutes, depending on the skills they want to measure.In mathematics, for example, you can give students eight questions and five minutes to complete them all. Or, in reading, you can give them a one-minute reading test.Upon completing the CBM test, you’d record the number of correct and incorrect answers or words on a graph.Plotting these points against the expected performance in various subject areas helps school administrators, teachers, and parents visualize students’ academic progress.Though formative in nature, Wright clarifies:
These CBM probes are given under standardized conditions. For example, the instructor will read the same directions every time that he or she gives a certain type of CBM probe… The child’s performance on a CBM probe is scored for speed, or fluency, and for accuracy of performance.
Disadvantages of traditional testing methods[caption id="attachment_3461" align="aligncenter" width="600"] Credit: US Department of Education [Public domain], via Wikimedia Commons[/caption]At the right time and in the right place, traditional academic or “norm-referenced” tests serve a legitimate purpose.When creating these tests, developers rely on statistical methods in order to choose the norming group, interpret scores, and determine benchmarks.According to The Glossary of Education Reform, “norm-referenced tests report whether test takers performed better or worse than a hypothetical average student.”Interestingly, however, “norming groups typically comprise only a small subset of previous test takers, not all or even more previous test takers.”What traditional academic tests can’t effectively do is:
1. Gauge student growth[caption id="attachment_3462" align="aligncenter" width="600"] Credit: Difference in Norm-Referenced and and Criterion-Referenced Tests adapted from Brown (1992)[/caption] Norm-referenced tests already occur infrequently. What’s worse, depending on them to monitor student progress can result in missing opportunities to fill small yet significant learning gaps.
2. Keep up with student progressThese types of tests happen too infrequently to address and adapt to students’ academic needs.Even when completing a norm-referenced test twice per year, there’s such a large gap between assessments that knowing whether or not certain teaching strategies worked becomes very challenging.
3. Match local or classroom curriculumThe questions and content areas included in a norm-referenced test won’t always align with the skills a student has learned leading up to it.Results could mislead you to think students are underperforming when, in reality, they were unfamiliar with the test content.
4. Highlight a specific class’ skill levels[caption id="attachment_3463" align="aligncenter" width="600"] Credit: Chris Yarzab[/caption] Performance standards of norm-referenced tests are set according to a national average. This approach is to ensure all schools can use them, understandably.However, teachers are well aware that class averages can vary drastically from national ones. Therefore, traditional tests can’t necessarily pinpoint a group of students’ true learning gaps.Reading this might lead you to wonder how much more effective curriculum-based measurement is than other testing methods.
Advantages of curriculum-based measurementUsing CBM in the classroom comes with number of great advantages. What curriculum-based measurement can do is:
1. Take minimal time to administer[caption id="attachment_3464" align="aligncenter" width="600"] Credit: Ilmicrofono Oggiono[/caption] Whether measuring math, reading, or writing fluency, CMBs take hardly any time. For example, in under five minutes, teachers can assign group math or individual reading probes.
2. Effectively gauge short-term student growthCBM probes quickly provide teachers with their class’ average academic performance.In contrast to norm-referenced tests, curriculum-based measurements enable teachers to identify students who are struggling to acquire and apply specific academic skills.
3. Be given regularly[caption id="attachment_3465" align="aligncenter" width="608"] Source: Jim Wright's "Curriculum-Based Measurement: A Manual for Teachers"[/caption] The more data the better, which is why CBM probes are so effective. For instance, teachers who want to gauge their students’ math fluency in a short timespan can run daily three-minute tests for two weeks.With two weeks of math fluency results plotted on individual graphs, teachers can visualize student progress and identify learning gaps.Prodigy, for example, uses adaptive learning technology which adjusts content to accommodate different learning styles and tackle trouble spots. On top of that, it provides Progress, Student Comprehension, Student Usage reports, and more.And the sooner these are identified, the higher the chances are of student progress.
4. Inform a teacher’s instruction[caption id="attachment_3466" align="aligncenter" width="600"] Credit: ASU Department of English[/caption] Because CBM enables such close monitoring of student progress, or lack thereof, teachers can also improve or adjust their instruction.If students are failing to acquire foundational academic skills crucial to future success, a teacher might:
- Increase instructional time
- Implement different teaching strategies
- Switch up grouping arrangements (e.g., individual vs small-group instruction)
Teachers who use CBM to monitor the effectiveness of instructional interventions tend to achieve significantly higher rates of student learning than those instructors who rely on more traditional test measures.
5. Motivate students to improve[caption id="attachment_3468" align="aligncenter" width="618"] Source: Jim Wright's "Curriculum-Based Measurement: A Manual for Teachers"[/caption] Praising students for their achievements is highly encouraged. But there’s something about seeing progress -- seeing the upward tick -- that excites children.Showing students their progress graphs week over week emphasizes ownership, and can help motivate them to strive for higher grades or set more ambitious academic goals.Note: There’ll be students whose graphs won’t show an “upward tick.” So, it may be helpful to show students their graphs individually as opposed to posting ongoing results on a dedicated wall.
6. Guarantee curriculum overlap[caption id="attachment_3469" align="aligncenter" width="600"] Source: Jim Wright's "Curriculum-Based Measurement: A Manual for Teachers"[/caption] With CBM, teachers create probes with materials they pull directly from curriculum. This guarantees that students will answer questions they’ve already encountered in the classroom.What’s more, curriculum overlap gives teachers a clearer idea of where students are succeeding or struggling based on what’s actually -- not hypothetically -- being taught.Note: There are times when norm-referenced tests align with what students have learned. More often than not, however, classrooms across the nation are in different places and learning at different paces.
7. Be a trustworthy alternative testing method[caption id="attachment_3470" align="aligncenter" width="600"] Credit: Marie[/caption] For over 30 years, educators have extensively researched curriculum-based measurement in special and general education. Tindal writes, in his brief history of CBM:
It has become a term used widely in the special education literature and has become the backbone of response-to-intervention (RTI), serving as the preferred form of progress monitoring used to evaluate instructional programs.Indeed, its staying power has been a function of (testimony to) its compatibility with traditional measurement development and the applications of standards for educational and psychological testing.Indeed, one of the core focuses on CBM was the need for technical adequacy, something which was not embedded into the fiber of the other systems.
8. Help strengthen parent involvementParent involvement, as EdCan outlines, comes in different shapes and forms:
- Behaviorally involved -- parents who volunteer at school or attend school functions
- Cognitively involved -- parents who expose their children to stimulating activities, e.g., reading or visiting cultural institutions
- Personally involved -- parents who positively communicate about school with their children
The relationship between parental involvement and academic achievement was positive, regardless of a definition of parental involvement or measure of achievement.Furthermore, the findings reveals that this relationship was strongest if parental involvement was defined as parental expectations for academic achievement of their children…Finally, the relationship between parental involvement and academic achievement was found to be consistent across different grade levels and ethnic groups.[caption id="attachment_3471" align="aligncenter" width="600"] Credit: Pete[/caption] Teachers using curriculum-based measurement can share these detailed results with parents, too!What better way to further engage parents than to provide weekly, let alone daily, insights into their child’s progress?Kathleen McLane worked for 21 years at the Council for Exceptional Children and joined the American Association on Intellectual and Developmental Disabilities in January 2014.In an article for the National Center on Student Progress Monitoring, McLane writes to parents:
CBM can help parents and teachers communicate more constructively. You can use the CBM graph in conferences with teachers and administrators, as it gives you specific information about your child’s progress and the success of the instructional methods being used.You can also use the CBM graph in IEP (Individualized Educational Program) meetings, to go over specific information about your child’s current performance so that you and the school can develop measurable goals and objectives that will lead to more meaningful progress for your child.
Examples of CBM probes[caption id="attachment_3472" align="aligncenter" width="600"] Source: Track RTI[/caption] Typically, teachers give students CBM probes to assess their reading, spelling, writing, and math skills.Below, adapted from Wright’s CBM Workshop Manual, are examples of what curriculum-based measurement can look like in each subject area.
ReadingWhen measuring reading fluency, it’s best to do this on an individual basis.A teacher will sit down with one student who’ll read two or three selected passages aloud for one minute each. The teacher will record any errors that occurred while reading the passages.Next, they’ll take an average of the correctly read words from each passage -- this will be considered the student’s true reading rate.
SpellingWhen assessing spelling, teachers may read aloud 10 to 15 words in two minutes, which their students must try to spell with little to no errors.They’ll score students based on the correct letter-sequences -- i.e., properly placed pairs of letters in a word.Take the word “spot” as an example which, as you’ll see, has five correct letter-sequences:Note: Teachers will assume the underscores before and after the word to be space-holders.In this case, teachers would score “spot” out of five -- one mark per correct letter-sequence.
WritingUsing a story-starter, teachers will give students one minute to think of a storyline and three minutes to write as much of it as possible.A story-starter can look something like: One day, I was at a carnival with my friend. All of a sudden, 100 balloons started floating away…Teachers can score writing CBM probes in a number of ways. For example, they can emphasize the number of words written, the number of words spelled correctly, or a combination of of the two.

MathematicsThere are two types of math probes:
- Single-skill, e.g., focusing only on multiplication
- Multiple-skill, e.g., focusing on both multiplication and division
However, when each individual digit is scored, it becomes clear that the student actually correctly computed 7 of 10 possible digits (70 percent).Thus, the CBM procedure of assigning credit to each correct digit demonstrates itself to be quite sensitive to a student’s emerging, partial competencies in math computation.[caption id="attachment_3474" align="aligncenter" width="600"] Credit: Reynold Bennett[/caption]
