  1. 2013 STARInterpreting and Using Results August 7, 2013 Webcast Webcast starts at 9 a.m.

  2. Objectives Workshop participants will be able to: • Describe the purposes of STAR reports • Interpret STAR results • Explain key statistics • Compare and contrast types of reports • Identify proper uses of reports Post-Test Workshop

  3. Agenda • What’s New? • Results and Statistical Analysis • Using Results • Summary and Internet Reports • Data CDs • Individual Student Reports • Early Assessment Program Post-Test Workshop

  4. Standards-based Tests in Spanish (STS) performance levels are now also reported for students in grades 8–11who took the grade-level STS for RLA, STS for Algebra I, and STS for Geometry. The score for the California Standards Test (CST) for Writing is no longer doubled; possible scores are 1, 2, 3, and 4. What’s New in 2013 Manual (M) 2 – 3 Post-Test Workshop

  5. What’s New in 2013 • ELA scale scores for the grades 4 and 7 CSTs and California Modified Assessment (CMA) will be provided based on the multiple-choice items only and the reporting cluster “Writing Applications” is no longer part of the CST and CMA ELA cluster groups; instead, the writing score is provided as a standalone score called “Writing Response Score.” M 2 – 3 Post-Test Workshop

  6. What’s New in 2013 • Enrollment and exit code data to determine which students are counted as “continuously enrolled” for accountability purposes, previously collected for (CBEDS), were not collected on STAR answer documents or in Pre-ID. Instead, these data were extracted from the California Longitudinal Pupil Achievement Data System (CALPADS). • Please refer to pages 2 and 3 in the 2013 Post Test Guide for a list of all changes. M 2 – 3 Post-Test Workshop

  7. Quiz Question 1 Which of these tests had scale scores reported for the first time in 2013? • CST for World History • STS for Science • CMA for Algebra I • STS for Algebra I Post-Test Workshop

  8. Quiz Question 1 Which of these tests had scale scores reported for the first time in 2013? CST for World History CAPA for Science CMA for Algebra I STS for Algebra I Post-Test Workshop

  9. Results: Purposes of STAR Reports • Report progress toward proficiency on the state’s academic content standards • Notify where improvement needed • To help students’ achievement • To improve educational programs • Provide data for state and federal accountability programs M 4 Post-Test Workshop

  10. Results: Performance Levels • State goal: All students score at proficient or above • 350 or higher scale score • CST • CMA • STS • CAPA proficient: 35 or higher scale score M 8 – 11 Post-Test Workshop

  11. Results: Other Performance Levels • Advanced • Basic cut score • CST: 300 • CMA: 300 • STS: 300 • CAPA: 30 • Below basic • Far below basic • For each testing program, cut pointsvary for advanced and below basic by • Subject • Grade M 8 – 11; Appendix B Post-Test Workshop

  12. Results: Scale Scores • Scale scores allow the same score to mean the same thing across test versions within grade and content area. • Scale scores account for differences in difficulty. • Scale score ranges by program are: • CST, CMA, STS: 150–600 for each grade and subject • CAPA: 15–60 for each level and subject M 8 – 11 Post-Test Workshop

  13. Results: Equating • Psychometric procedure • Adjusts for test difficulty • Additional information in the technical report on the CDE Web site M 8 Post-Test Workshop

  14. Results: Reporting Clusters (Content Area) • Three to six clusters for each subject • May be useful as indicators of individual or group strengths and weaknesses • But. . . reporting clusters should be interpreted with caution M 9 – 11; Appendix A Post-Test Workshop

  15. Results: Reporting Clusters Cautions • Cluster percent correct available for CSTs, CMA, STS • Based on small numbers of items; therefore, may not be reliable or generalized • NOT equated from year to year • Should not compare reporting cluster percent correct from year to year M 9 – 11; Appendix A Post-Test Workshop

  16. Interpreting Reporting Clusters or Content Areas in the Same Year • Compare to percent-correct range of proficient students statewide M 9 – 11; Appendix A Post-Test Workshop

  17. 2013 CST Reporting Clusters: Number of Questions and Average Percent Correct 2013 Post-Test Guide, Appendixes A and C as posted on startest.org, will be finalized with complete data on August 15. M Appendix A Post-Test Workshop

  18. Examples—Interpreting Reporting Clusters for the CST for Geometry M 10 Post-Test Workshop

  19. Quiz Question 2 What is a scale score? • Percent correct of all questions • Mean percent correct of all questions • An adjustment of this year’s and last year’s raw scores to show changes • An adjustment of the raw score to account for differences in difficulty Post-Test Workshop

  20. Quiz Question 2 What is a scale score? • Percent correct of all questions • Mean percent correct of all questions • An adjustment of this year’s and last year’s raw scores to show changes • An adjustment of the raw score to account for differences in difficulty Post-Test Workshop

  21. Using Results • For instructional decisions in conjunction with other data • Used in Academic Performance Index (API) calculations, all grades and subjects: CST, CMA, CAPA • Used in adequate yearly progress (AYP) calculations, ELA and mathematics: • CST — grades 2–8 • CMA — grades 3–8 • CAPA — grades 2–8, 10 M 4 Post-Test Workshop

  22. Year-to-Year Comparisons Do Compare CSTs: Same Grade and Same Content Area • Mean scale score • Same content and grade, varying years • Percent in each performance level • Same content by grade across years • e.g., 2012 grade 10 ELA with 2013 grade 10 ELA M 12 – 15 Post-Test Workshop

  23. Year-to-Year Comparisons Do Compare CSTs: Percent Proficient and Advanced • Percentage of students scoring at PROFICIENT and above • For a given grade and subject, e.g., Percent proficient and above for grade 3 math in 2012 and 2013 • For a given subject and aggregated grades, e.g., Percent proficient and above for grades 2–6 mathematics in 2012 and 2013 • Across grades and a subject, e.g., Percent proficient and above in all courses and all grades M 12 – 15 Post-Test Workshop

  24. Year-to-Year Comparisons Don’t Compare • Individual scale scores or statistics based on scale scores for different grades or content areas • Subjects by grade are independently scaled • Different content standards are measured in different grades • Cohorts across grades • Across tests • Scale scores to percent correct scores • CAPA to years prior to 2009, due to new standard setting then M 12 – 15 Post-Test Workshop

  25. Example—Using CST Results to Compare Grade Results from Year to Year M 14 Post-Test Workshop
