  • Hidden:Doctors use blood pressure to predict general healthBlood tests Future:Colleges use SAT & GPA to predict college successInsurance companies use credit scores to predict the risk a driver will get into an accidentWe want to use the alignment results to identify which students are at risk for not meeting proficiency on the state test.
  • With regard to Washington State Proficiency – like other states, we have a moving target from grade to grade. A student who is proficient one year may not be proficient the next only because the state’s performance expectation is different.10th grade is at the 26th percentile!Hypothetical 41st percentile student…
  • Other half served by EvergreenUsing MAP for about 5 years
  • NWEA provides the value at which a student has 50/50 odds of passing the MSP. Also, odds for each of our 4 levels… but all WE really care about is passing. Values for Spring RIT are interesting – but there’s no predictive power there…
  • Fortunately there are values for Fall, but not Winter.
  • The values from the prior two tables can be plotted – similar to the Highline modelNote – there’s a similar chart for Reading too.
  • NWEA also provides the probability of passing for RIT scores in 5 RIT bands. This is more useful – but can be overwhelming…. And what do you do with a score of 202?
  • Questions in the back of my mind…Which gives better results?Worked with friends in other districts… can’t be that hard, can it? Data sharing agreements Defining dates – what does Fall 2011 mean? Data errors – grade level reported for THIS year, not year the data reflectsI know regression methodologies and I’m suspicious of Equipercentile.Highline appeared to have better ideas for applying the informationPooled 2 years of data from 7 districts
  • I tested all kinds of variables…
  • I tested all kinds of variables and all provided very good correlation values.I selected Winter HIMAP because…
  • Need lead time, so everything “Spring” was outMissing data was a problem. Especially if we want to use results for prediction and for many reasons, HIMAP provided the largest NI liked the logic of HIMAP – easy to not care and get an under-report. Hard to cheat to a high score.And Winter is an optional test window for most grades in Vancouver
  • The Cut Scores were almost identical across the 3 methods in Reading
  • … and in Math
  • Then I applied Highline’s plus/minus 4 RIT to create 3 bands – same idea, but I used different names for the 3 resulting categories.Explain chart – “Of the kids that Multi-Dist analysis predicted to likely not be proficient in Reading, only 15% surprised us. Of those in the 50/50 range, 55% were proficient. Of those that we predicted to be proficient, 92% met expectations.
  • So, taking this chart we looked at earlier………..
  • And taking the values from this chart, we can create a teacher report….
  • This is a sample teacher report I plan to distribute after the Fall window closes.

    • 3. About the MAP Assessments• Computerized• Adaptive assessment – increases in difficulty when answers are correct and decreases in difficulty when answers are incorrect.• Rasch Units (RIT) Scale • Equal Interval • Vertical scaling • Has the same meaning regardless of grade or age of the student.• For the purposes of this presentation, we will be looking at Reading & Math only.
    • 4. Value of Alignment StudiesResearchers align scales for one of two purposes:• Use results from measure “X” to predict the value of a harder-to-observe measure or outcome “Y”.• Use results from measure “X” to predict the value of a future measure or outcome “Y”.In our case, faculty and administration are interested inidentifying students who are likely to struggle on futurestate performance measures. By intervening early, wecan target resources to students who may not meet“proficiency”.

    • 6. About Vancouver Public Schools• About 22,000 enrolled students• 6 High Schools (4 comprehensive, 1 magnet, 1 alternative)• 18% of students speak a language other than English at home• 53% eligible for free or reduced price lunch• The district serves half of the city of Vancouver, WA (across the river from Portland)
    • 7. About Highline Public Schools• About 18,000 enrolled students• 15 High Schools (2 comprehensive, 6 small learning community, 1 magnet, 5 alternative, 1 skills center)• 43% of students speak a language other than English at home - 21% ELL.• 68% eligible for free or reduced price lunch• The district serves neighborhoods of White Center, Burien, Des Moines, SeaTac and Normandy Park just south of Seattle.
    • 8. Highline’s Regression Study• In 2007, School and District Administration had been requesting ways to interpret student MAP scores in context of (then) WASL testing. One concern in particular was that students had been above average on the national norms, but yet were not meeting standard on the state assessment.• School staff also requested a way to quickly identify if a student was on track or not.
    • 9. Highline’s Regression Study• Decided to do a regression analysis to predict WASL performance.• Ran correlations on multiple variables, and found that “HiMap” (max of last 3 test administrations) had a higher correlation with WASL than a single MAP score. • Weeds out test “bombs” and missing data
    • 10. “HIMAP” Variable Defined Fall Winter SPRING HIMAP HIMAP HIMAP 5th Grade 5th Grade 5th Grade
    • 11. Highline’s Regression Study• Rather than make a straight out prediction of whether a student will meet/not meet standard, we wanted to emphasize the possible predictive error.• Decided to find a cut on the MAP assessment to predict 400 on WASL, and then generate an error band around that where students would be considered “too close to call”• Used 4 points as a generous estimate of the standard error of the assessment (usually between 3-3.5)
    • 12. Intervention Categories: 3 “Bands”• “Above Benchmark” students were those who performed more than 4 RIT points above the cut score. These students are considered on track to meet standard.• “Strategic” students were those who performed within 4 RIT points of the cut. These students are “too close to call” and should receive strategic intervention to meet standard.• “Intensive” students were those who performed more than 4 RIT points below the cut score. These students are unlikely to meet standard without intensive intervention.
    • 13. Cuts for Fall, Winter and Spring• When the study was first done in 2008, regression analyses were performed using Spring MAP scores and WASL.• Growth norms were utilized to back track to get cuts for Fall and Winter• Cut scores and ranges were disseminated to teachers and administrators, along with an explanation of the scores.• Excel files for schools began including MAP scores, along with each students’ “BSI Indicator”, color coded in Red, Yellow and Green.
    • 14. Predictive Validity• When a student’s indicator is compared to their actual performance: • Approximately 90% of students identified as “Above Benchmark” actually met standard. • Approximately 50% of students identified as “Strategic” actually met standard. • Approximately 10% of students identified as “Intensive” actually met standard.• These were generally true within about 10 percentage points
    • 15. 2010 MSP• The analysis was re-run in 2010 following the first year of transition from WASL to MSP.• During the second analysis, regressions were run on each test window individually in each grade level, finding individual cuts, rather than using growth norms.• District budget cuts made high school MAP testing optional, and therefore High School was excluded.
    • 16. 2012 MSP• Due to online testing for MSP along with other district initiatives requiring lab time, our Spring window was moved from May to March beginning in Spring 2012. Also, Winter testing became an optional window.• Therefore, cuts were created one more time in 2012 for Highline. Again, regressions were done between Fall MAP and MSP, and Spring MAP and MSP. Because Winter was optional, the cuts for Winter were determined using the 2/3 point between the Fall and Spring cuts.
    • 17. NWEA’s Linking Study • Most recently updated in Feb, 2011 • Based on a sample of 271 schools in the Spring of 2010 • NWEA uses an Equi-percentile method to equate test results
    • 18. Equipercentile Method ofAlignment • NWEA used a sample of students from 271 schools taking the 2010 spring assessment in WA. • For each grade and subject, identify the percentage of students in the study sample that met standard. • For each grade and subject, identify the RIT associated with the equivalent percentile from within the study sample.“If 40% of the study population in grade 3 mathperformed below the proficient level on the statetest, we would find the RIT score that would beequivalent to the 40th percentile for the studypopulation”
    • 19. Multi-District Regression Study• Included 7 districts including Seattle, Bellingham, Vancouver, Highline, Sumn er, Auburn, and Clover Park• Data covered the 2009-10 and 2010-11 academic years• The “cut score” for proficiency was consistent across both years at each grade level, so data from both years was pooled• Overall N of approximately 80,000
    • 20. Independent Variables Created• Math Spring RIT (Winter and Fall as well)• Math Spring HIMAP (Winter and Fall as well)• Combined Spring HIMAP (sum of Read & Math) (Winter and Fall as well)• Math Winter HIMAP + Math MSP• Math Fall HIMAP + Math MSP(Comparable variables were also created for Reading)
    • 21. Quality of CorrelationBest: (Corr: 0.78) • Spring RIT (but no predictive value, so Spring indicators will be ignored)Next Best: (Corr: 0.73-0.75) • Winter RIT • Winter HIMAP + MSP scale score (275-500) • Winter HIMAPThird Best: (Corr: 0.70) • Read Winter HIMAP + Math Winter HIMAP
    • 22. Rationale for Selecting Winter HIMAP• Spring MAP test window overlaps MSP/HSPE test window.• Prior Year MSP scores not available for grades 3 and 10.• New students in district are missing MSP scores.• Not all students perform to their best ability on every test.• Many students do not take the Winter MAP.
    • 23. Rationale for Selecting Winter HIMAPWinter HIMAP …• Is not very different in the quality of the correlation as compared to other options,• Maximizes the number of students for whom it can be applied, and• Is relatively easy to explain
    • 24.

    • 25. Pro and Con of Do-It-YourselfPro: • Data are based on “our kids” (this is an emotional argument, not a statistical one). • Winter and prior spring estimates can be computed rather than estimated.Con:• It is a lot of work.• Controlling for test windows is complex.• NWEA results are very similar to DIY results.• Teachers who encounter the NWEA linking study will be confused about why our cut points are different.• … and did I say it was a lot of work?
