• What’s New?• Results and Statistical Analysis• Using Results• Summary and Internet Reports• Data CDs• Individual Student Reports• Teacher Reports• Early Assessment Program

HO 1


What’s New in 2009What’s New in 2009

• CMA reports– Scale score, performance levels for grades 3–

5 – Percent correct for grades 6–8– Writing scores for grades 4 and 7

• CAPA new cut scores for all including scale scores for science

• STS reports– Scale score, performance levels for grades 2–

4 – Percent correct for grades 5–11

• Data CD: two files only

HO 2–3


Results: Results: Purposes of STAR ReportsPurposes of STAR Reports

• Report progress of students 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

HO 4


Results: Results: Performance Levels Performance Levels

• State Goal: All students score at proficient or higher

• CAPA Proficient: 35 or higher scale score

• 350 or higher scale score– All CST– STS, grades 2–4– CMA, grades 3–5

HO 4


Results: Results: Other Performance LevelsOther Performance Levels

• Advanced• Basic Cut Score

– CAPA: 30– CST: 300 – CMA, grades 3–5: 300– STS, grades 2–4: 300

• Below basic• Far below basic• Cut points vary for

advanced and below basic by – Subject– Grade

HO 4


Results: Scale ScoresResults: Scale Scores

• Scale scores allow same score to mean same thing across test versions within grade and content area

• Scale score ranges by program:– CST, CMA (grades 3–5), STS (grades 2–4):

150–600 for each grade and subject– CAPA: 15–60 for each level and subject

HO 5


Results: Equating Results: Equating

• Psychometric procedure

• Adjusts for test difficulty

• Additional information in the CST Technical Report on the CDE Web site

HO 5


Results: Reporting ClustersResults: Reporting Clusters(Content Areas)(Content Areas)

• 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

HO 6–7


Results: Cluster Percent Correct Results: Cluster Percent Correct Available for 2009Available for 2009

• CST: all• CMA:

– Grades 3–5– Grade 7: Writing only

• STS– Grades 2–4– Grades 5–7, but no comparison with

proficient students statewide


Results: Reporting ClusterResults: Reporting ClusterCautionsCautions

• 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

Using ResultsUsing Results

• For instructional decisions with other data• Used in Academic Performance Index (API)

calculations: CSTs, CAPA, CMA (grades 3–5 only)

• Used in adequate yearly progress (AYP) calculations, ELA and mathematics: – Grades 2–8 CSTs– Grades 3–5 CMA– Grades 2–8 and 10 CAPA


Year-to-Year ComparisonsYear-to-Year ComparisonsDoDo Compare CSTs: Compare CSTs:

Same Grade and Same Content AreaSame 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., 2008 ELA grade 10 with 2009 ELA grade 10

HO 9


Year-to-Year ComparisonsYear-to-Year ComparisonsDoDo Compare CSTs: Compare CSTs:

Percent Proficient and AdvancedPercent 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 2008 and 2009

– For a given subject and aggregated grades, e.g., Percent proficient and above for grades 2– 6 mathematics in 2008 and 2009

– Across grades and a subject, e.g., Percent proficient and above in all courses and all grades

HO 9


Year-to-Year ComparisonsYear-to-Year ComparisonsDON’TDON’T Compare 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• CAPA, CMA, STS to previous years

divided by the number of students tested.– Not included:

Incomplete tests Modified tests Non-English learners who took the STS Unknown EOC mathematics (except grade 7 math) or science

tests Inconsistent grades

score x 600score x 600

• Reporting Clusters not comparable– Different difficulty

– Varying number of questions

– Average % correct of clusters % correct of total scale score

• Scale scores– Use conversion tables and other statistical

techniques

– Equating allows scores to have similar meaning (e.g., 350 = lowest score for CSTs proficient)


Other Student ReportsOther Student Reports• CMA

– Performance levels grades 3–5 – Percent correct grades 6–8– Back, “About the CMA,” – Back, cluster reporting grades 3–5 and grade 7 writing

California Reports for TeachersCalifornia Reports for Teachers

• Summary of results for previous year’s class(es)• Two types of summary reports:

– By grade level (e.g., grade 11 ELA) or course (e.g., Algebra I) for all schools

– By teacher name or group name (e.g., GATE) if on Pre-ID or SGID (latter takes precedence)

• Separate reports for:– CST ELA– CST Mathematics

• Not available for:– CST science or history–social science– CMA – CAPA– STS


California Reports for TeachersCalifornia Reports for Teachers

• Individualized reports (teacher name or group name)– if name on SGID or Pre-ID– SGID takes priority over Pre-ID

• Group reports (grade level or course): all ELA and mathematics teachers should receive

• EOC Math– Grades 7–11 by subject only– Not grade-specific:

e.g., All Algebra I in a school
