Results: Purposes of STAR Reports M 3 • 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 Post-Test Workshop
Results: Performance Levels M 8−9 • State goal: All students score at proficient or higher • 350 or higher scale score • All CST • CMA for ELA in grades 3–9, math in grades 3–7 and Algebra I, and science in grades 5, 8, and 10 • STS for RLA and math in grades 2–7, excluding Algebra I • CAPA proficient: 35 or higher scale score Post-Test Workshop
Results: Other Performance Levels M 8−9;Appendix B • Advanced • Basic cut score • CST: 300 • CMA: 300 for ELA in grades 3–9, math in grades 3–7, Algebra I, science in grades 5, 8, and 10 • STS: 300 for RLA and math in grades 2–7 (excluding Algebra I) • CAPA: 30 • Below basic • Far below basic • For each testing program, cut pointsvary for advanced and below basic by • Subject • Grade Post-Test Workshop
Results: Scale Scores M 7−11 • Scale scores allow the same score to mean the same thing across test versions within grade and content area • Accounts for differences in difficulty • Scale score ranges by program: • CST, CMA (ELA grades 3–9, mathematics 3–7, Algebra I, science in grades 5, 8, and 10), STS (grades 2–7, excluding Algebra I): 150–600 for each grade and subject • CAPA: 15–60 for each level and subject Post-Test Workshop
Results: Equating M 7 • Psychometric procedure • Adjusts for test difficulty • Additional information in the technical report on the CDE Web site Post-Test Workshop
Results: Reporting Clusters(Content Areas) M 9−11;Appendix A • 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 Post-Test Workshop
Results: Cluster Percent Correct Available for 2011 M 9−11;Appendix A • CST: all • CMA: • Grades 3–9 ELA, grades 3–7 math, Algebra I, grades 5, 8, and 10 science • STS: all Post-Test Workshop
Results: Reporting ClusterCautions M 9−11;Appendix A • 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
Interpreting Reporting Clusters or Content Areas in the Same Year M 8−12;Appendix A • Compare to percent-correct range of proficient students statewide Post-Test Workshop
2011 CST Reporting Clusters: Number of Questions and Average Percent Correct M Appendix A 2011 Post-Test Guide, Appendices A and C as posted on startest.org will be finalized with complete data on August 15. Post-Test Workshop

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
Quiz Question 2 What is a scale score? D. An adjustment of the raw score to account for differences in difficulty Post-Test Workshop
Using Results M 3 • For instructional decisions with other data • Used in Academic Performance Index (API) calculations: CSTs, CAPA, CMA (only grades 3–9, Algebra I, Life Science) • Used in adequate yearly progress (AYP) calculations, ELA and mathematics: • Grades 2–8, CSTs • Grades 3–8 and Algebra I, CMA • Grades 2–8 and 10, CAPA Post-Test Workshop
Year-to-Year ComparisonsDo Compare CSTs:Same Grade and Same Content Area M 12−15 • Mean scale score • Same content and grade, varying years • Percent in each performance level • Same content by grade across years • e.g., 2010 grade 10 ELA with 2011 grade 10 ELA Post-Test Workshop
Year-to-Year ComparisonsDo Compare CSTs:Percent Proficient and Advanced M 12−15 • 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 2010 and 2011 • For a given subject and aggregated grades, e.g., Percent proficient and above for grades 2– 6 mathematics in 2010 and 2011 • Across grades and a subject, e.g., Percent proficient and above in all courses and all grades Post-Test Workshop
Year-to-Year ComparisonsDON’T Compare M 12−15 • 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 • CMA grades 9−11, STS grades 8−11 to previous years • CMA grades 6−8, STS grades 5−7, only compare 2011 to 2010 • CAPA, CMA grades 3−5, STS grades 2−4, DON’T compare to years before 2009 Post-Test Workshop
