Descriptive Information

Please provide a description of your tool:

Acadience Math is a screening and progress monitoring assessment used to measure math skills. The Acadience Math screening measures are efficient indicators of math skills. For each grade and time of year, the Acadience Math component measures that correlate highly with later outcomes are combined to form a Math Composite Score. The component measures used in the Composite Score depend upon grade and time of year. The Composite Score is the best overall predictor of later outcomes and conveys that all of the aspects of math proficiency are critical.

Provide information about special accommodations for students with disabilities.

Approved accommodations are any accommodations that will not alter the standardization of the assessment. Specific approved accommodations include, but are not limited to: 1. The use of colored overlays, filters, or lighting adjustments for students with visual impairments. 2. The use of student materials that have been enlarged or with larger print for students with visual impairments. 3. The use of assistive technology, such as hearing aids and assistive listening devices (ALDs), for students with hearing impairments. 4. The use of a marker or ruler to focus student attention on the materials for students who are not able to demonstrate their skills adequately without one. Unapproved accommodations are accommodations that are likely to change how the assessment functions (such as modifying the timing rules or reading Concepts and Applications items to students). Scores from measures administered with unapproved accommodations should not be treated or reported as official Acadience Math scores and cannot be compared to other Acadience Math scores or benchmark goals but can be used to measure individual growth for a student. An unapproved accommodation may be used when (a) a student cannot be tested accurately using the standardized rules or approved accommodations, but the school would still like to measure progress for that student; or (b) a student’s Individualized Education Plan (IEP) requires testing with an unapproved accommodation. For more information about accommodations please see the Acadience Math Assessment Manual.

If yes, please describe.

The Acadience Math benchmark goals provide targeted levels of skill that students need to achieve by specific points in time in order to be considered to be making adequate progress. The Stanford Achievement Test Series, Tenth Edition–Total Math score (SAT10; Pearson, 2003), a high-quality, nationally norm-referenced assessment, was used as an external criterion in the validity study. In the validity study, the 40th percentile at or above the SAT10 Total Math Raw Score was used as one approximation of adequate math skill. The intent is to develop generalizable benchmark goals and cut points that are relevant and appropriate for a wide variety of math outcomes, across a wide variety of states and regions, and for diverse groups of students. The principle vision for Acadience Math is a step-by-step vision. Student skills at or above benchmark at the beginning of the year put the odds in favor of the student achieving the middle-of-year benchmark goal. In turn, students with skills at or above benchmark in the middle of the year have the odds in favor of achieving the end-of-year benchmark goal. Finally, students with skills at or above benchmark at the end of the year have odds in favor of having adequate math skills on a wide variety of external measures of math proficiency. The fundamental logic for developing the benchmark goals and cut points for risk was to begin with the external outcome goal and work backward in that step-by- step system. We first obtained an external criterion measure (the SAT10 Total Math Raw Score) at the end of the year with a level of performance that would represent adequate math skills (the SAT10 Total Math Raw Score at the 40th percentile rank). Next, we specified the benchmark goal and cut point for risk for end-of-year Composite Score with respect to the end-of-year external criterion. Then, using the Composite Score end-of-year goal as an internal criterion, we established the benchmark goals and cut points for risk for middle-of-year Composite Score. Finally, we established the benchmark goals and cut points for risk for beginning-of-year Composite Score using the middle-of-year Composite Score goal as an internal criterion (see the Acadience Math Benchmark Goals Document). The same standard setting methodology used for the Acadience Math Composite was also used for each individual Acadience Math component measure.

Can you provide evidence in support of multiple decision rules?

Yes

If yes, please describe.

Research evidence supporting the use of Acadience Math measures for benchmark assessment three times per year is found in the Acadience Math Technical Adequacy Brief, Acadience Math Assessment Manual, and the Acadience Math Benchmark Goals document.

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.

In second through sixth grade, the Computation and Concepts and Applications component assessments are combined into an overall Math Composite Score. Depending on the grade level and time of year, different weights may be given to the component assessments. Math Composite Scores can be calculated manually or automatically. If calculating manually, Math Composite Score worksheets are provided.

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.

The Acadience Math measures were developed to provide teachers with information they need to make decisions about instruction. The authors advocate a data-based decision-making model referred to as the Outcomes-Driven Model, because the data are used to make decisions to improve student outcomes by matching the amount and type of instructional support with the needs of the individual students. These steps of the model repeat each trimester (i.e., beginning of year, middle of year, and end of year) as a student progresses through the grades. At the beginning of the trimester, the first step is to identify students who may need additional support. At the end of the trimester, the final step is to review outcomes, which also facilitates identifying students who need additional support for the next trimester. In this manner, educators can ensure that students who are on track to become proficient at math continue to make adequate progress, and that those students who are not on track receive the support they need to become proficient at math. Step 1: Identify need for support early. This process occurs during benchmark assessment, and is also referred to as universal screening. The purpose is to identify those students who may need additional instructional support to achieve benchmark goals. The benchmark assessment also provides information regarding the performance of all students in the school with respect to benchmark goals. All students within a school or grade are tested three times per year on grade-level material. The testing occurs at the beginning, middle, and end of the school year. Step 2: Validate need for support. The purpose of this step is to be reasonably confident that the student needs or does not need additional instructional support. Before making individual student decisions, it is important to consider additional information beyond the initial data obtained during benchmark testing. Teachers can always use additional assessment information and knowledge about a student to validate a score before making decisions about instructional support. If there is a discrepancy in the student’s performance relative to other information available about the student, or if there is a question about the accuracy of a score, the score can be validated by retesting the student using alternate forms of the Acadience Math measures or additional diagnostic assessments as necessary. Step 3: Plan and implement support. In general, for students who are meeting the benchmark goals, a good, research-based core classroom curriculum should meet their instructional needs, and they will continue to receive benchmark assessment three times per year to ensure they remain on track. Students who are identified as needing support are likely to require additional instruction or intervention in the skill areas where they are having difficulties. Step 4: Evaluate and modify support as needed. Students who are receiving additional support should be progress monitored more frequently to ensure that the instructional support being provided is helping them get back on track. Students should be monitored on the measures that test the skill areas where they are having difficulties and receiving additional instructional support. Monitoring may occur once per month, once every two weeks, or as often as once per week. In general, students who need the most intensive instruction are progress monitored most frequently. Step 5: Review outcomes. By looking at the benchmark assessment data for all students, schools can ensure that their instructional supports—both core curriculum and additional interventions—are working for all students. If a school identifies areas of instructional support that are not working as desired, the school can use the data to help make decisions on how to improve. The use of Acadience Math measures within the Outcomes-Driven Model is consistent with the most recent reauthorization of the Individuals with Disabilities Education Improvement Act (IDEA), which allows the use of a Response to Intervention (RtI) approach to identify children with learning disabilities. In an RtI approach to identification, early intervention is provided to students who are at risk for the development of learning difficulties. Data are gathered to determine which students are responsive to the intervention provided and which students need more intensive support (Fuchs & Fuchs, 2006). The Outcomes-Driven Model is based on foundational work with a problem-solving model (see Deno, 1989; Shinn, 1995; Tilly, 2008) and the initial application of the problem-solving model to early literacy skills (Kaminski & Good, 1998). The general questions addressed by a problem-solving model include: What is the problem? Why is it happening? What should be done about it? Did it work? (Tilly, 2008). The Outcomes-Driven Model was developed to address these questions, but within a prevention-oriented framework designed to preempt early math difficulty and ensure step-by-step progress toward outcomes that will result in established, adequate math achievement.

*Describe each criterion measure used and explain why each measure is appropriate, given the type and purpose of the tool.

The Stanford Achievement Test Series, Tenth Edition–Total Math score (SAT10; Pearson, 2003) was used as the external criterion. The SAT10 is a widely used, timed, group-administered, norm-referenced achievement test appropriate for children in kindergarten through grade 12. In second through sixth grade, the SAT10 Total Math score includes scores from the subtests of Mathematics Problem Solving and Mathematics Procedures. Students are given 80 minutes in total to complete both subtests. The SAT10 Total Math score was compared to all Acadience Math measures given during the year, providing both predictive criterion-related validity correlations for beginning- and middle-of-year measures and concurrent criterion-related validity data for end-of-year measures.

*Describe the sample(s), including size and characteristics, for each validity analysis conducted.

Validity data were collected during the 2017–2018 school for second through sixth grade. This sample included 537 students across five schools in four districts in four US states. Demographic information is not available for this sample.

*Describe the analysis procedures for each reported type of validity.

Predictive validity is the correlation between the Math Composite Score, which includes the Computation and Concepts and Applications component measures, at the beginning of the year and the SAT 10 score at the end of the school year. This coefficient represents the extent to which Math Composite Score can predict later math outcomes. Concurrent validity is the correlation between the Math Composite Score and the SAT 10 measure both at the end of the year. This coefficient represents the extent to which the Math Composite Score is related to important math outcomes.

*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.
