October 2017

2. Test Administration
State requires assessments for grades 3-8 & 11. Cedar Falls assesses ALL students in grades 3-11.
Tests administered in Reading, Mathematics, and Science
Schools administer assessment in the Spring.
Iowa Assessments revised in – impacted proficiency levels
New assessment anticipated for administration in

3. Analyzing the Results
Cross Sectional Cohorts - Grade level – year to year
Example: Comparing 5th grade over time
Compares different students
Simple Cohorts – Same group of students over time
Compares the same group of students as they progress through system – May not be the same students
Focus is on GROWTH
Simple Cohort Growth – compares percent of students in 3 proficiency levels (non/prof/adv)
Expected Growth (new in 2015)
Growth Bands – compares average individual growth within 5 growth levels (bands)

16. Focus on GROWTH
Analyzing Cohorts

17. Simple Cohort Growth
Compares test results of group/class of students (cohort) as they progress through the system – grades 3-11
Average NSS score growth from year to year
Percent of students in each proficiency level (non, prof, adv prof) each year
Proficiency, Advanced Proficiency determined by NSS Scores provided by state

18. Cohort Growth By Grade Levelto

21. Science Cohort Growth
Not provided

22. Cohort Growth by Proficiency
Following one cohort (class) as it progresses through the system

23. These graphs are in Bev’s Working Docs > Iowa Assessments > (Form F) > Data & Graphs > Simple Cohort data graphs

26. Analyzing Expected Growth
Students are categorized into one of 5 performance levels (bands) based on NSS Score and NPR (National Percentile Rank)
Average growth for students within each band is compared with expected growth of students within that band (as determined by the state)
The expected growth is the “realistic” growth that is expected for students within that growth band

31. NSS Growth – All Students Combined
Regardless of beginning proficiency level (band) in

32. NSS Growth (Met/Not Met) as Compared to Expected NSS Growth

33. Final Summary
Cedar Falls students continue to outperform students in AEA/State
Overall, the percent of non-proficient students continues to decrease in Reading, Math, and Science
While there continues to be gaps in proficiency between subgroups, the gap is shrinking
The focus on growth (simple cohort and expected growth) allows staff to sort the data and “drill deeper” into the data in analyzing student by student, skill by skill, as well as by class and building
