If yes, please describe.
Please describe the scoring structure. Provide relevant details such as the scoring format, the number of items overall, the number of items per subscale, what the cluster/composite score comprises, and how raw scores are calculated.
All scores are calculated automatically by the software. The software calculates a maximum likelihood Rasch ability estimate based on the calibrated difficulty of the items that were administered to the student, and the pattern of the student’s right and wrong responses to those items. Star Reading uses a proprietary, Rasch-based, 1-parameter logistic response model to calculate scores. The scaled score is a non-linear, monotonic transformation of the Rasch ability estimate resulting from the adaptive test. From the scaled scores and the student’s current grade placement are derived grade equivalent, percentile, and normal curve equivalent scores. No clusters, composite, or raw scores are reported.
Describe the tool’s approach to screening, samples (if applicable), and/or test format, including steps taken to ensure that it is appropriate for use with culturally and linguistically diverse populations and students with disabilities.
Star Reading is trusted by tens of thousands of schools to efficiently screen and monitoring student progress in general reading achievement from grades 1 through 12. Both criterion- and norm-referenced scores are automatically reported to help teachers make a variety of instructional decisions. The choice to adopt a computer adaptive format was driven by a demand for efficiency and protecting instructional time, standardizing administration and scoring and avoiding threats to reliability, and ability to dynamically adapt the instrument to each student in real time to appropriately match their current level of proficiency. Reports and dashboards guide educators through screening and related decisions. Default risk categories, based on national norms, are provided, although they can be adjusted by local school leaders to best fit local populations. Additionally, projections to state summative and other high stakes tests such as ACT and SAT are provided to inform screening decisions. During Star Reading item development, every effort is made to avoid the use of stereotypes, potentially offensive language or characterizations, and descriptions of people or events that could be construed as being offensive, demeaning, patronizing, or otherwise insensitive. The editing process also includes a strict sensitivity review of all items to attend to issues of gender and ethnic-group balance and fairness. DIF analyses are conducted to ensure the items function equally well for diverse subgroups.

PARCC Reading

Classification Accuracy

Select time of year
Describe the criterion (outcome) measure(s) including the degree to which it/they is/are independent from the screening measure.
The PARCC assessment is an external outcome measure administered at least 90 days after each student’s Star assessment.
Do the classification accuracy analyses examine concurrent and/or predictive classification?

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).
The Star cut-point for students at risk was determined to be at the 25th percentile of Star scores. This point aligns with students in need of intervention, as indicated in Star default benchmarks. Students scoring below the 25th percentile were placed into the at-risk category and students scoring above the 25th percentile were placed into the no-risk category. Consistent with the TRC guidelines, we selected the 20th PR on the outcome measure as the point aligned with students in need of intensive intervention.
Were the children in the study/studies involved in an intervention in addition to typical classroom instruction between the screening measure and outcome assessment?
No
If yes, please describe the intervention, what children received the intervention, and how they were chosen.

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 the performance on Star to performance on the criterion measure. Selection of Star 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.

Classification Accuracy

Select time of year
Describe the criterion (outcome) measure(s) including the degree to which it/they is/are independent from the screening measure.
DIBELS is an external outcome measure administered outside of the Star suite of assessments.
Do the classification accuracy analyses examine concurrent and/or predictive classification?

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 the performance on Star to performance on the criterion measure. Selection of Star 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.

*Offer a justification for each type of reliability reported, given the type and purpose of the tool.
The internal consistency reliability coefficient estimates the proportion of variability within a single administration of a test that is due to inconsistency among the items that comprise the test
*Describe the sample(s), including size and characteristics, for each reliability analysis conducted.
For each grade, a large sample (n = 100,000) of students completed Star Reading assessments throughout the 2012–2013 school year
*Describe the analysis procedures for each reported type of reliability.
Reliability was defined as the proportion of test score variance that is attributable to true variation in the trait the test measures. The variance of the test scores was calculated from Scaled Score data. The variance of the errors of measurement was estimated from the conditional standard error of measurement (CSEM) statistics that accompany each of the IRT-based test scores, including the Scaled Scores. The conditional standard error of measurement (CSEM) was calculated along with the IRT ability estimate and Scaled Score. Squaring and summing the CSEM values yielded an estimate of total squared error; dividing by the number of observations yielded an estimate of error variance. Generic reliability was calculated by subtracting the ratio of error variance to Scaled Score variance from 1.

*Describe each criterion measure used and explain why each measure is appropriate, given the type and purpose of the tool.
All criterion measures were external to the screening tool system and represent widely used assessments of general reading ability. • CAT-5. The California Achievement Test, is a nationally normed standardized test that measures achievement in reading. • ITBS. The Iowa Tests For Basic Skills are nationally normed standardized tests that offer educators a diagnostic look at how their students are progressing in reading comprehension. • PARCC. The Partnership for Assessment of Readiness for College and Careers end-of-year assessment covers reading and is intended to be used as an indicator of student needs and progress. • SBA. Smarter Balanced assessments are summative tests designed to measure student achievement and growth in reading to support teaching and learning. • ACT. The American College Testing college readiness assessment is a national standardized test for high school achievement and college admissions. • SAT EBRW. The SAT Evidence-based reading and writing assessment is a standardized test widely used for college admissions in the United States.
*Describe the sample(s), including size and characteristics, for each validity analysis conducted.
Samples included students who had taken both Star Reading and the criterion measure. The sample sizes varied across criterion and grades, ranging from 105 to 10,800 students.
*Describe the analysis procedures for each reported type of validity.
Concurrent and predictive correlations were calculated. A criterion assessment was considered concurrent if it was taken within approximately 30 days of Star Reading. Predictive correlations involve a criterion assessment occurring outside of the concurrent window for Star Reading.

*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.

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:
Logistic regression analyses conditional on ability, group membership, and ability by group interaction were conducted to assess the presence of both uniform and non-uniform DIF simultaneously. Additionally, an effect size measure – Nagelkerke R-squared – was computed to quantify the magnitude of DIF where present.
b. Describe the subgroups for which bias analyses were conducted:
DIF analyses were conducted for gender (males and females) and race/ethnicity (Caucasian, African American, American Indian, Asian, and Hispanic subpopulations). Due to insufficient samples sizes on English Language Learner (ELLs) and students with disabilities (SWD), DIF analyses for these two subgroups were not possible at the time of the analyses.
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.
Using a blended criterion that flagged items for uniform/non-uniform DIF if they had a p-value less than 0.01 and Nagelkerke R2 greater than or equal to 0.035, the results indicated that Star Reading is sufficiently bias-free. A total of 153 items (2% of the Star Reading items) were flagged for DIF. Those flagged items were removed from the item banks for review and recalibration.
