CBM • Teachers assess students’ academic performance, using brief measures, on a frequent basis. • The major purposes are • To describe rate of response to instruction • To build more effective programs. • With CBM, student performance on a global indicator of academic competence is assessed on a frequent basis.
ROOTS OF CBM • Deno at University of Minnesota Institute for Research on Learning Disabilities (Deno, 1986) • Effort to develop and validate simple methods for use in IEP’s
ASSESSMENT NEEDS • Use curriculum • Short in duration • Multiple forms • Inexpensive • User friendly • Show improvement over time • Research based
CHARACTERISTICS OF ALL CBA MODELS • Test stimuli drawn from the curriculum • Repeated testing occurs over time • Useful in instructional planning
Three Purposes of CBM 1) Screening 2) Progress Monitoring • Teachers assess students’ academic performance on a regular basis • To determine whether children are profiting appropriately from the typical instructional program • To build more effective programs for children who do not benefit appropriately from typical instruction 3) Instructional Diagnosis
CBM Screening Examples: • Beginning of Grade 1: students who say less than 15 sounds in 1 minute. • Beginning of Grade 2: students who read less than 40 words from text in 1 minute.
DIFFERENCES FROM TRADITIONAL MEASURES • Does not try to determine why child is having trouble • But how different from the norm • And is he/she getting better?
ACCOUNTABILITY • CBM can document effectiveness by showing change over time • Provides a baseline of performance to determine if related services are leading to change over time • Achievement and accountability decisions are made on basis of classroom performance
STAFF ACCEPTANCE • Testing more relevant • Confidence in test results • Can compare to peers • Improved communication with parents • Motivating to students to see growth
What We Look For in CBM INCREASING SCORES: Student is responding to the instructional program. FLAT SCORES: Student is not responding to the instruction program.

DEVELOPING PROBES • Developed from student’s actual curriculum • Allow for quick administration and scoring • Reading probes • Math probes • Spelling • Written language
READING PROBE • One on one administration • Three one-minute tests • Score is number of correct words read • Errors noted • Median score • Grade level reading rates
CBM Global Indicators of Reading Competence • Kindergarten: Letter-Sound Fluency • Grade 1: Word-Identification Fluency • Grades 2-3: Passage Reading Fluency • Grades 4-6: Maze Fluency
Pre-Reading CBM • Kindergarten: Phonemic-Segmentation Fluency • Kindergarten: Letter-Sound Fluency • Early First Grade: Nonsense-Word Fluency • Early First Grade: Word-Identification Fluency

Grades 2-3 Passage Reading Fluency • Number of words read aloud correctly in 1 minute on end-of-year passages
Jason Fry ran home from school. He had to pack his clothes. He was going to the beach. He packed a swimsuit and shorts. He packed tennis shoes and his toys. The Fry family was going to the beach in Florida. The next morning Jason woke up early. He helped Mom and Dad pack the car, and his sister, Lonnie, helped too. Mom and Dad sat in the front seat. They had maps of the beach. Jason sat in the middle seat with his dog, Ruffie. Lonnie sat in the back and played with her toys. They had to drive for a long time. Jason looked out the window. He saw farms with animals. Many farms had cows and pigs but some farms had horses. He saw a boy riding a horse. Jason wanted to ride a horse, too. He saw rows of corn growing in the fields. Then Jason saw rows of trees. They were orange trees. He sniffed their yummy smell. Lonnie said she could not wait to taste one. Dad stopped at a fruit market by the side of the road. He bought them each an orange. CBM passage for Correct Words Per Minute
CBM Passage Reading Fluency • Not interested in making kids read faster • Interested in kids becoming better readers • The CBM score is an overall indicator of reading competence • Students who score high on CBM • Are better decoders • Are better at sight vocabulary • Are better comprehenders • Correlates highly with high-stakes tests
Grades 4-6 Maze Fluency • Number of words replaced correctly in 2.5 minutes on end-of-year passages from which every 7th word has been deleted and replaced with 3 choices
MATH PROBE • Variety of types of problems the student will encounter • Group administration • Three to five minute test • “Correct digits” is the number of digits in the correct place on each problem

In RTI, CBM Is Used To … 1. Identify Risk with Screening 2. Monitor Response to GE (general educational response) 3. Eliminate Poor Instruction as Explanation for Poor general educational response 4. Designating Non-Response (LD)
2. For At Risk, Monitoring Response to GE • Administer weekly CBM to all at-risk students for 6-8 weeks. • At end of 6-8 weeks, identify children whose slope (rate of improvement) is substantially less than peers.
Tutoring Small Group Instruction (1:1, 1:3, 1:5, 1:10) • 10 wks, 4x per wk, 35-45 min per session • Point system for motivation • Train to mastery • Immediate corrective feedback • Mastery of content before moving on • More time on difficult activities • More opportunities to respond • Fewer transitions • Setting goals and self monitoring • Special relationship with tutor
RTI Overview • Fall CBM screen cut-point to designate risk < 15 • Monitor at-risk students weekly for 8 weeks to determine GE response (GE is Open Court Reading). • Students whose CBM slope (rate of improvement) across the 8 weeks of GE is low (< 1.8 word/week increase) enter preventive tutoring. • Preventive tutoring: 3 times/week for 12 weeks; 45 min per session in groups of 3; taught by trained and supervised paraprofesional
In summary, CBM is used for: • to identify at-risk students who may need additional services • to help general education teachers plan more effective instruction within their classrooms • to help special education teachers design more effective instructional programs for students who don’t respond to the general education program • To document student progress for accountability purposes • To communicate with parents or others professionals about students’ progress
