Introduction The following report presents the system-wide percentile ranks for the DIBELS Math measures of early numeracy, computation, and concepts and applications for kindergarten through sixth grade. The results are presented by grade and time of year for which these measures are used for benchmark assessment (beginning-, middle-, and end-of-year). The DIBELS Math system-wide percentile ranks are based on data entered into Dynamic Measurement Group s DIBELSnet data reporting system (https://dibels.net/) for the 2014-2015 school year. System-Wide Percentile Ranks and Local Norms The DIBELS Math system-wide percentile ranks allow a school or district to compare a student s performance to other students within the same data system. When examined in conjunction with local (school or district) norms, the DIBELS Math system-wide percentile ranks can be used as an additional frame of reference for evaluating a student s skill level in foundational mathematics. The primary interpretation of DIBELS Math scores, however, should continue to be with respect to the benchmark goals. DIBELS Math benchmark goals are empirically derived target scores that represent adequate progress in mathematics. If a student achieves a benchmark goal, then the odds are in favor of that student achieving later math outcomes if the student receives instruction from a research-based core curriculum. In order for the odds to be in favor of future success in mathematics, students need to score at or above the benchmark goal, regardless of where their score falls relative to system-wide or local norms. For more information about the benchmark goals, see the DIBELS Math Preliminary Benchmark Goals and Composite Score document at https://dibels.org/mathearlyrelease/. In addition, we recommend prioritization of local norms over system-wide percentile ranks when interpreting student performance. Local norms allow a school or district to compare an individual student s performance to other students in the same district. Local norms have the important advantage of being representative of the student s district, even if they are not necessarily representative of the national population. If the average achievement in a given district is below the national average achievement score, all percentile ranks would be affected. For instance, a student with an average score of 19 on DIBELS Math Computation (COMP) at the middle of third grade would be below the benchmark goal for the measure. This score would place the student at the 30th percentile according to system-wide percentile ranks, but may be at the 65th percentile on local norms if the average achievement in the district is below the system-wide average. When considering how to utilize limited resources for mathematicsbased intervention services, this student's local percentile may indicate lower priority for limited support resources than a student whose scores indicate much lower performance according to local norms. There are times, however, when system-wide percentile ranks can provide additional clarification regarding student performance. For example, this same student might appear to have average skills in the local context, but the system-wide normative information clarifies that the student s skills are below average in a larger context (see Table A). Taking into account benchmark goals and local norms, the DIBELS Math system-wide percentile ranks can provide a more complete and nuanced perspective on the student s skills and needs. 2

It is also important to consider the characteristics of students in a particular district. For example, a local district may have a very high proportion of English-language learners. While the DIBELS Math system-wide percentile ranks include English-language learners, the proportion may or may not be representative of the local district. A second consideration is the national distribution of demographic characteristics. System-wide percentile ranks may be more representative of some states than others. Specific norms for a particular state may be less representative of the nation as a whole, but more representative of students in the state. It is important for district and school leaders to review the demographic information presented in this report in order to assess the relevance of the DIBELS Math system-wide percentile ranks for their student population prior to making decisions about individual students or overall district performance. For system-wide, norm-referenced interpretations with DIBELS, descriptors for levels of performance are provided in Table A. The performance descriptors are intended to describe the current level of skill for a student in comparison to other students in DIBELSnet. They are not intended as statements of achievement and do not reflect what the student is capable of learning with targeted, effective instruction. Table A. Levels of Performance Percentile Rank Ranges 98th percentile and above 91st to 97th percentile 76th to 90th percentile 25th to 75th percentile 9th to 24th percentile 3rd to 8th percentile 2nd percentile and below Performance Descriptors: Compared to other students in the DIBELSnet sample, the student s performance is: Upper Extreme Well-Above Average Above Average Average Below Average Well-Below Average Lower Extreme Even when interpreting scores at the percentile level, the DIBELS measures should be viewed as screening and progress monitoring tools that help identify students who may need additional instructional support and monitor their progress toward meaningful goals. A student s future ability in mathematics is unknown and not fixed at the time of the initial screening. Instead, outcomes in mathematics are the result of both the student s initial skills and the targeted, differentiated instruction and intervention that are provided as a direct result of the screening information. If the initial screening predicts a less-than-adequate performance, then the instructional goal is to change the prediction for the better. For example, if a student's scores reflect Well-Below Average performance on the beginning-of-year second grade assessment, then he or she is likely to need additional instructional support to be successful. The goal is for the student to achieve improved outcomes, (i.e., Above Average scores in first third grade), as a result of providing targeted, differentiated instruction and early intervention. 3

Description of the Sample The percentile ranks for DIBELS Math are based on a large national sample of school-age children across the United States. This sample was collected and entered into DIBELSnet by school personnel at three benchmark assessment time points (fall or beginning-of-year, winter or middle-of-year, and spring or end-of-year) during the 2014-2015 school year. Data were exported from DIBELSnet in July 2015. Students with recorded data from all three benchmark assessments were retained. The final sample included approximately 71,805 students in kindergarten through sixth grade from 387 schools within 181 school districts. Summaries of each measure's percentile score rankings for DIBELS Math are reported by grade in Tables 1 7 (pages 7-13). Exact percentile ranks for each score on each DIBELS Math measure are reported by measure in Tables 8 11 (pages 14-50). System-wide Percentile Rank Interpretation The percentile rank that corresponds to each score represents the system-wide skill level of the DIBELSnet population, and can be used to compare the performance of individual students to a nation-wide sample population. For example, if a third grade student scored 28 on DIBELS Math Computation at the middleof-year benchmark assessment, then, according to the summary Table 3 on page 9 and the exact percentile rank in Table 9 on page 17, her score falls at the 65 th percentile rank of the system-wide sample. This means that, in addition to scoring above benchmark on the measure, the student performed as well as or better than approximately 65% of other students within the DIBELS Math system-wide percentile ranks and was in the average range based on the performance descriptors in Table A. Alternatively, if the student scored 20 on DIBELS Math Computation, then her score falls in the average range. From Table 3, a score of 20 falls between the 30 th and the 35 th percentile. Table 9 provides the exact rank of the 34 th percentile. This means that 34% of other students within the DIBELS Math system-wide percentile ranks population scored as well as or lower than the student. 4
