Star CBM
Passage Oral Reading
Summary
The Star CBM Passage Oral Reading measures include grade-level passages for teachers and other school personnel to use in screening to establish student achievement in reading, to set goals for those students, to monitor their progress, and to evaluate the effectiveness of instruction for the purpose of modifying instruction when indicated. The essential procedures were developed by researchers at the University of Minnesota beginning in 1977 and the years following. The reading passages were initially written in 1988 and disseminated as the Standard Reading Passages by Children’s Educational Services. In 2019, those passages were acquired by Renaissance Learning and incorporated into Star Curriculum Based Measurement as the Passage Oral Reading measures.

Measures of Academic Progress (MAP)
Classification Accuracy
- Describe the criterion (outcome) measure(s) including the degree to which it/they is/are independent from the screening measure.
- The Measures of Academic Progress (MAP) was used as the outcome measure. Published by the NWEA the MAP is regarded as a highly valid and reliable measure of broad reading ability. The NWEA website states, “Our tools are trusted by educators in 140 countries and more than half the schools in the US” which indicates it can be considered an excellent outcome measure for classification studies on the Oral Reading measure studied here.
- Describe when screening and criterion measures were administered and provide a justification for why the method(s) you chose (concurrent and/or predictive) is/are appropriate for your tool.
- Describe how the classification analyses were performed and cut-points determined. Describe how the cut points align with students at-risk. Please indicate which groups were contrasted in your analyses (e.g., low risk students versus high risk students, low risk students versus moderate risk students).
- Using the SPSS program ROC analyses were conducted on the sample. The Oral Reading data (Words Read Correctly) was administered in the Winter of grade 1. MAP was used to determine students “at-risk” and in “intensive need” and was administered three months later in the Spring (as specified in the NCII criteria). The 20th percentile on the MAP was used to determine the cut-points on the MAP. The results of the ROC analysis provided the Area Under the Curve (AUC) with 95% confidence intervals for determining the lower and upper bounds. In addition, the ROC analysis provides the Coordinates of the Curve provide Sensitivity and Specificity estimates. In addition, the coordinates are used to determine “risk” cut-points on Oral Reading that are associated with different levels of sensitivity and specificity. The cut-points on the Oral Reading were then used for further classification analysis in determining overall correct classification rates, false positives, false negative, Positive Predictive Power and Negative Predictive Power.

Minnesota Comprehensive Assessment (MCA) - Reading
Classification Accuracy
- Describe the criterion (outcome) measure(s) including the degree to which it/they is/are independent from the screening measure.
- The 2nd criterion used in our classification analysis is the Minnesota Comprehensive Assessment (MCA) in reading. The MCA is the state accountability test for Minnesota and has been established by the Minnesota Department of Education to be a highly reliable and valid measure or reading. See http://education.state.mn.us/MDE/dse/test/mn/Tech/ for more technical information. The MCA is an external measure.

Dynamic Indicators of Basic Early Literacy Skills (DIBELS)
Classification Accuracy
- Describe the criterion (outcome) measure(s) including the degree to which it/they is/are independent from the screening measure.
- The Dynamic Indicators of Basic Early Literacy Skills (DIBELS) was developed by University of Oregon's Center on Teaching and Learning (CTL) and assesses the acquisition of early literacy skills. The DIBELS Oral Reading Fluency (ORF) is a standardized test of accuracy and fluency with connected text.
- Describe when screening and criterion measures were administered and provide a justification for why the method(s) you chose (concurrent and/or predictive) is/are appropriate for your tool.
- Describe how the classification analyses were performed and cut-points determined. Describe how the cut points align with students at-risk. Please indicate which groups were contrasted in your analyses (e.g., low risk students versus high risk students, low risk students versus moderate risk students).
- A ROC analysis was used to compare performance on Star CBM to DIBELS ORF performance. Selection of Star CBM cut scores was based on striking an optimal balance between specificity and sensitivity when classifying students as “at risk”. For these analyses, students scoring below the Star cut score are classified as “high risk” and students scoring at or above the Star cut score are classified as “low risk”. Students scoring below the 20th percentile on the criterion measure are considered to be “actually at risk” and students scoring at or above the 20th percentile on the criterion measure are considered to be “actually not at risk”. As a result, students classified as “at risk” on Star and are considered to be “actually at risk” represent a true positive. Students classified as “at risk” on Star, but are “actually not at risk” represent a false positive. Students classified as “not at risk” on Star, but are “actually at risk” represent a false negative. Students classified as “not at risk” on Star and are “actually not at risk” represent a true negative.
- Were the children in the study/studies involved in an intervention in addition to typical classroom instruction between the screening measure and outcome assessment?
- If yes, please describe the intervention, what children received the intervention, and how they were chosen.

Star Reading
Classification Accuracy
- Describe the criterion (outcome) measure(s) including the degree to which it/they is/are independent from the screening measure.
- Star Reading is a online computer adaptive assessment of general reading ability developed by Renaissance Learning. Although they now share a common name, Star Reading is entirely independent to Star CBM POR. The Star CBM POR measures were recently purchased by Renaissance Learning, the publisher of Star Assessments, in 2019. The POR measures were originally named Standard Reading Passages, and were developed by Dr. Stanley Deno and Dr. Douglas Martson in 1985 under the auspices of Children’s Educational Services, Inc. Therefore the POR and Star Reading measures were developed entirely independently of one another, at different times (the POR passages predate Star Reading by more than a decade), by different individuals and organizations.
- Describe when screening and criterion measures were administered and provide a justification for why the method(s) you chose (concurrent and/or predictive) is/are appropriate for your tool.
- Describe how the classification analyses were performed and cut-points determined. Describe how the cut points align with students at-risk. Please indicate which groups were contrasted in your analyses (e.g., low risk students versus high risk students, low risk students versus moderate risk students).
- A ROC analysis was used to compare performance on Star CBM to Star Reading performance. Selection of Star CBM cut scores was based on striking an optimal balance between specificity and sensitivity when classifying students as “at risk”. For these analyses, students scoring below the Star cut score are classified as “high risk” and students scoring at or above the Star cut score are classified as “low risk”. Students scoring below the 20th percentile on the criterion measure are considered to be “actually at risk” and students scoring at or above the 20th percentile on the criterion measure are considered to be “actually not at risk”. As a result, students classified as “at risk” on Star and are considered to be “actually at risk” represent a true positive. Students classified as “at risk” on Star, but are “actually not at risk” represent a false positive. Students classified as “not at risk” on Star, but are “actually at risk” represent a false negative. Students classified as “not at risk” on Star and are “actually not at risk” represent a true negative.

- *Describe each criterion measure used and explain why each measure is appropriate, given the type and purpose of the tool.
- The Measures of Academic Progress (MAP) was used as the outcome measure. Published by the NWEA the MAP is regarded as a highly valid and reliable measure of broad reading ability. The NWEA website states, “Our tools are trusted by educators in 140 countries and more than half the schools in the US” which indicates it can be considered an excellent outcome measure for classification studies on the Oral Reading measure studied here. See https://www.nwea.org/normative-data-rit-scores/ for more information. The MAP is an external measure. A second criterion used in our analysis is the Minnesota Comprehensive Assessment (MCA) and reading. The MCA is the state accountability test for Minnesota and has been established by the Minnesota Department of Education to be a highly reliable and valid measure or reading. See http://education.state.mn.us/MDE/dse/test/mn/Tech/ for more technical information. The MCA is an external measure.
- *Describe the sample(s), including size and characteristics, for each validity analysis conducted.
- For the Concurrent and Predictive validity analyses for Passage Reading and MAP there was a total sample of 9,410 students (grades 1-6). Demographic data indicated 48.4% of the sample was female, 12.4% was special education, 24.0% received Title services, 7.5% was served in a gifted program, 38.2% received free or reduced lunch, and 5.1% received ELL service. Ethnic percentages for this sample were 1.3% for American Indian, 4.9% for Asian American, 10.3% for Hispanic American, 7.7% for Black American, and 75.8% for White American. For the Concurrent and Predictive validity analyses for Passage Reading and MCA there was a total sample of 11,094 students (grades 3-6). Demographic data indicated 48.2% of the sample was female, 12.4% was special education, 27.2% received Title services, 9.3% was served in a gifted program, 27.6% received free or reduced lunch, and 7.7% received ELL service. Ethnic percentages for this sample were 2.6% for American Indian, 4.0% for Asian American, 9.4% for Hispanic American, 12.2% for Black American, and 71.8% for White American.
- *Describe the analysis procedures for each reported type of validity.
- Two types of validity analysis were conducted; Concurrent and Predictive. The Concurrent study used Pearson Product Moment Correlational analysis to examine the relationship between Passage Reading (Words Read Correctly) and the MAP and the MCA. All measures were administered in the Spring of 2017. The Predictive study used Pearson Product Moment Correlational analysis to examine the relationship between Passage Reading (Words Read Correctly) and the MAP and the MCA. Passage Reading was administered in the Winter of 2017 and the criterion measures of MAP and MCA were administered in the Spring of 2017, approximately three months later.
*In the table below, report the results of the validity analyses described above (e.g., concurrent or predictive validity, evidence based on response processes, evidence based on internal structure, evidence based on relations to other variables, and/or evidence based on consequences of testing), and the criterion measures.

- Manual cites other published reliability studies:
- No
- Provide citations for additional published studies.
- Describe the degree to which the provided data support the validity of the tool.
- Validity coefficients for both concurrent and predictive validity are typically high. The median correlation coefficient for concurrent validity is .73 and is .70 for predictive validity.
- Do you have validity data that are disaggregated by gender, race/ethnicity, or other subgroups (e.g., English language learners, students with disabilities)?
- Yes
If yes, fill in data for each subgroup with disaggregated validity data.

- Have you conducted additional analyses related to the extent to which your tool is or is not biased against subgroups (e.g., race/ethnicity, gender, socioeconomic status, students with disabilities, English language learners)? Examples might include Differential Item Functioning (DIF) or invariance testing in multiple-group confirmatory factor models.
- Yes
- If yes,
- a. Describe the method used to determine the presence or absence of bias:
- Classification analyses were performed using a sample of Grade 1 through 6 data obtained from the spring of 2022 where students took the CBM Passage Oral Reading measure and Star Reading. Receiver Operating Character (ROC) curve analyses were performed to evaluate the diagnostic classification accuracy of the Passage Oral Reading measure for identifying students as being at risk on Star Reading. For Star Reading, the cut point for defining at risk was set at the 20th percentile. The Area Under the ROC (AUC) was computed separately by grade and subgroup with 95% confidence intervals estimated for each AUC estimate. The confidence intervals for the different subgroups in each grade were compared and evaluated to determine whether there was differential classification accuracy.
- b. Describe the subgroups for which bias analyses were conducted:
- Separate analyses were performed for Gender, Ethnicity, Special Education Status, and English Language Learner Status.
- c. Describe the results of the bias analyses conducted, including data and interpretative statements. Include magnitude of effect (if available) if bias has been identified.
- In all but one comparison, the 95% AUC confidence intervals for the subgroups in each grade overlapped and there were not statistically significant differences in classification accuracy. The one significant difference is classification accuracy was found between Whites and Blacks, where AUC for Whites was 0.84 and the AUC for Blacks was 0.81.
