    1. 2008 STARInterpreting and Using Results August/September 2008

    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 • Quiz • Post Test Guide • What’s New? • Results and Statistical Analysis • Using Results • Summary and Internet Reports • Individual Student Reports • Teacher Reports Post-Test Workshop

    4. Part I: General Info New in 2008 Interpreting Reports Comparing Results Part II: Report Descriptions Summary Individual Teacher Internet Part III: Appendices Reporting clusters Scale score ranges Statistical tables Test Score Verification procedures Demographic Data Correction procedures California reading list Glossary Post-Test Guide Layout Post-Test Guide Pages (Pp) i–iii Post-Test Workshop

    5. CMA reports Percent correct Grades 3–5 STS reports Percent correct Grades 5–7 added CAPA Science percent correct Ethnicity for Economic Status subgroup summary (CSTs only) STAR Student Reports sorted for district All without addresses All with addresses What’s New in 2008 Post-Test Guide P 2 Post-Test Workshop

    6. Results: Purposes of STAR Reports Post-Test Guide P 3 • Report progress of students toward proficiency on the state’s academic content standards • Inform where improvement needed • To help students’ achievement • To improve educational programs • Provide data for state and federal accountability programs Post-Test Workshop

    7. Results: Performance Levels Post-Test Guide P 7 • State goal: PROFICIENT or higher • Scale score of 350 or higher for CSTs • Scale score of 35 or higher for CAPA • Other performance levels: • Advanced • Basic (300 CSTs, 30 CAPA) • Below Basic • Far Below Basic • CST and CAPA cut points vary for Advanced, Below Basic, and Far Below Basic by • Subject • Grade Post-Test Workshop

    8. Results: Scale Scores Post-Test Guide P 7–8 • Scale scores allow same score to mean same thing across test forms within grade and content area and across time • Scale score ranges by program: • CSTs: 150–600 for each grade and subject • CAT/6 Survey: 1–999 for each grade and subject • CAPA: 15–60 for each grade and subject • CMA, STS, CAPA Science: Not available until 2009 Post-Test Workshop

    9. Results: Equating Post-Test Guide Page 7 • Psychometric procedure • Adjusts for test difficulty • Additional information in CST Technical Report on CDE Web site • For 2008 • CSTs and CAPA (except science) are equated • CMA (3–5),CAPA (science), and STS (2–4) and will be equated starting in 2009 • CAT/6 nationally norm-referenced; not equated for STAR Post-Test Workshop

    10. Results: Reporting Clusters(Content Areas) Post-Test Guide P 36 Appendices A & B • Four to six clusters for each content area (subject) • May be useful as indicators of individual or group strengths and weaknesses • But… Reporting clusters should be interpreted with caution Post-Test Workshop

    11. Results: Reporting ClusterCautions Post-Test Guide P 8–10 Appendices A & B • Based on small numbers of items; therefore may not be reliable or generalizable • NOT equated from year to year • Should not compare reporting cluster percent correct from year to year Post-Test Workshop

    12. Interpreting Reporting Clusters or Content Areas in the Same Year Post-Test Guide P 8–10; 84 Appendices A & B • CSTs—Performance on the clusters for students statewide scoring from • Lowest score for proficient to • Lowest score for advanced Post-Test Workshop

    13. CSTs 2008 Reporting Clusters — Number of Questions and Average Percent Correct Post-Test Guide Page 138(Appendix A) Post-Test Workshop

    14. Examples—Interpreting Reporting Clusters for CST for Geometry Post-Test Guide P 9 Post-Test Workshop

    15. Using Results Post-Test Guide P 3 • For instructional decisions withother data: CSTs, CMA, CAPA, STS • Used in Academic Performance Index (API) calculations: CSTs, CAT/6 Survey,CAPA • Used in adequate yearly progress (AYP) calculations for grades 2–8 in ELA and math for CSTs and 2–8 and 10 in ELA and math for CAPA Post-Test Workshop

    16. Year-to-Year ComparisonsDo Compare Same Grade and Same Content Area Post-Test Guide Pp 11–14 • Mean scale score • Same content and grade, varying years • Percent in each performance level • Same content by grade across years • e.g., 2007 ELA grade 10 with 2008 ELA grade 10 Post-Test Workshop

    17. Year-to-Year ComparisonsDo Compare Same Grade or Same Content Area Post-Test Guide Pp 11–14 • 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 2007 & 2008 • For a given subject and aggregated grades, e.g., % proficient and above for grades 2 to 6 math in 2007 & 2008 • Across grades and a subject, e.g., % proficient and above in all courses and all grades Post-Test Workshop

    18. Year-to-Year ComparisonsDON’T Compare Post-Test Guide Pp 11–14 • 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 • CMA, STS scores because notscaled Post-Test Workshop
